abstract

Factors associated with SARS-CoV-2 infection risk are still debated. This case-control study aims to investigate the possible relationship between SARS-CoV-2 infection, evaluated through antibody response, and the main sociodemographic, occupational, clinical-anamnestic, and biochemical factors in a population of Modena province (Northern Italy), mainly workers. Both workers who voluntarily joined the screening campaign proposed by companies and self-referred individuals who underwent serological testing were enrolled. Subjects with antibody positivity were recruited as cases (n = 166) and subjects tested negative (n = 239) as controls. A questionnaire on sociodemographic, occupational, and clinical data was administered through telephone interviews. Serum zinc/iron/copper/chromium/nickel, vitamins D/B12, folates, triglycerides, and LDL/HDL/total cholesterol were measured. Cases lived more often in urban areas (61.8% vs. 57%). Cases and controls did not differ significantly by working macrocategories, but the percentage of workers in the ceramic sector was higher among cases. Low adherence to preventive measures in the workplace was more frequent among seropositives. Folate concentration was significantly lower among cases. Therefore, adequate folate levels, living in rural areas, and good adherence to preventive strategies seem protective against infection. Workers in the ceramic sector seem to be at greater risk; specific factors involved are not defined, but preventive interventions are needed.

2018 - Sand Liquefaction Phenomena During the Seismic Crisis of May 2012 in Emilia, Northern Italy [Articolo su rivista]
Lugli, Stefano; Fontana, Daniela; Marchetti, Dori Simona; Fioroni, Chiara; Bertolini, Giovanni
abstract

In May 2012, the Emilia region of the Po Valley was struck by a seismic crisis with two major events of magnitude Mw6.1 and Mw5.9. The first event induced widespread sand blows formed along buried channels and old crevasse splay deposits. In the days immediately following the events, the detailed mapping and sampling of the erupted sand was fundamental to record all the seismically-induced phenomena. The study of a trench dug across large fractures at San Carlo (Ferrara) provided also valuable information on the sand blows mechanism and regome. The sedimentological and compositional characteristics of the fracture-filling materials indicate that the sands were erupted from a layer located between 6.8 and 7.5 m depth. Older and deeper Holocene and Pleistocene sand layers were not apparently involved in the liquefaction phenomena.

2017 - Source layer identification of liquefied sands ejected during the blast-induced liquefaction test at Mirabello (Ferrara, Italy) through a quantitative compositional study. [Abstract in Atti di Convegno]
Fontana, Daniela; Sara, Amoroso; Luca, Minarelli; MARCHETTI DORI, Simona; Marco, Stefani
abstract

It is well known that the occurrence of sand liquefaction phenomena may cause significant modifications of soil geotechnical properties and reduction of load-bearing capacity. Recent experiences (New Zealand, United States) have shown that liquefaction can be induced and monitored with field scale blast tests in order to study the related effects on soil chacacteristics. In this context the composition of sand blows represents an important tool to identify the liquefied layers. This study reports the composition of sands ejected during the blast-induced liquefaction test carried out in May 2016 at Mirabello (Ferrara, Italy). In 2012, the same area was largely affected by liquefaction phenomena during the Mw 6.1 Emilia earthquake. Sand samples analyzed in thin section (34 samples, 300 points for each sample, fraction 0125-0.250 mm) include blast-induced sand blows, sands from 2 cores at different depths in the subsurface (from 2 to 20 m) and sands from 2 trenches in the blast site representative of 2012 liquefied sands. The sands from the cores show a clear trend from lithoarenitic to quartz-feldspar-rich compositions. The sands at shallow depth (up to 7 m) are the most lithoarenitic, with sedimentary fine-grained rock fragments (shales and siltstones) as the dominant lithic type. Lithic fragments derive mostly from the erosion of sedimentary terrigenous and carbonate successions of Apenninic affinity. These shallow sands are well distinguishable from the deeper sands (at depth > 7 m) that show compositions slightly enriched in quartz and feldspars and impoverished in lithic fragments that suggest affinity with the Po river sands. The composition of ejected sands largely overlap that of the shallow Apenninic sands at depth from 6 to 7 m. Similarly the sands from the 2012 dikes show a composition of Apenninic affinity compatible with that of the shallow sands. Results from the blast test fit well with data obtained from the study of the sands ejected in the nearby area of San Carlo during the Mw 6.1 earthquake (Fontana et al., 2015). Also in this case, sand composition and fabric indicate that liquefaction processes affected mainly sand layers at relatively shallow depth ( 6.8-7.5 m). The study shows that composition of sands is crucial for a better understanding of earthquake-induced liquefaction mechanisms, in particular to identify the source layer of the sand blows and, more generally, for the recognition of critical levels prone to hazardous sand liquefaction phenomena.

2017 - Una formazione multidisciplinare e continua: l’esperienza del corso EMTASK [Capitolo/Saggio]
Lauriola, Paolo; Giovannetti, Enrico; MARCHETTI DORI, Simona; Soldati, Mauro
abstract

Uno degli assi prioritari del Sendai Framework riguarda la diffusione di conoscenze – attraverso la prevenzione e la preparazione degli individui, delle comunità e delle organizzazioni – che possono mitigare gli effetti dei disastri naturali e ridurre, dove possibile, il rischio che si verifichino. In Italia una simile formazione non è ancora disponibile in modo adeguato per rispondere a una domanda crescente, già attiva da parte delle amministrazioni pubbliche e del volontariato. A Modena, in seguito agli eventi calamitosi degli ultimi anni, l’Università, insieme al Comune, all’Esercito italiano e all’Agenzia regionale di prevenzione ambientale, ha organizzato un corso sulle emergenze territoriali, ambientali e sanitarie (emtask). Questa esperienza formativa fornisce spunti in merito a contenuti e metodi, all’organizzazione delle attività didattiche e al partenariato che si è mobilitato per definire obiettivi e modalità di realizzazione del corso: elementi rilevanti per avviare una progettazione modulare e “scalabile”.

2016 - Building materials and degradation phenomena of the Finale Emilia Town Hall (Modena): An archaeometric study for the restoration project after the 2012 earthquake [Articolo su rivista]
Lugli, Stefano; Caroselli, Marta; Marchetti Dori, Simona; Vandelli, Vincenzo; Marzani, Gaetano; Segattini, Roberto; Bianchi, Clara; Weber, Johannes
abstract

The Town Hall of Finale Emilia (18th century; Modena) is one of the 1600 historical buildings seriously damaged by the seismic crisis that affected the Emilia region of Northern Italy in May 2012 (ML 5.9). FAI, Fondo Ambiente Italiano (Italian National Trust) selected this important building for a complex restoration and structural strengthening project. A nationwide fundraising campaign was immediately launched to bring back to life the symbol of the community so badly struck by the earthquake. The restoration project is now in its executive phase under the scientific supervision of Direzione Regionale per i Beni Culturali e Paesaggistici. Among many other diagnostic tools that have been applied to elaborate the restoration project, detailed surveys and petrographic analyses were performed to characterize the ornamental stones, mortars and plasters and their alteration phenomena. In particular, the study of more than 40 samples provided fundamental information to distinguish different building phases. In the first construction phases all the raw materials (lime rock and sand) were taken from the Panaro River, the closest source to the palace. The more recent renovations saw the use of industrial materials coming from the Veneto area and the Po River.

2016 - Progress in mineralogical quantitative analysis of rock samples: Application to quartzites from Denali National Park, Alaska Range (USA) [Articolo su rivista]
Nistor, M. M.; Har, N.; Marchetti Dori, S.; Bigi, S.; Gualtieri, A. F.
abstract

This work deals with the determination of the mineralogical composition of three quartzite samples, selected as case study to verify the viability and accuracy of various experimental techniques commonly used in geometallurgy and petrography for the determination of the mineralogical composition of rock samples. The investigated samples are from the North-Eastern side of the Denali National Park (Alaska Range, USA). The mineralogical phase abundance of the samples was determined by digitally assisted optical modal point counting, scanning electron microscopy (SEM) + energy dispersive spectroscopy (EDS) modal and digital image analysis, normative calculation from bulk chemistry calculation, and modal Rietveld X-ray powder diffraction. The results of our study indicate that the results provided by modal optical and SEM digitalized counting seem less accurate than the others. The determination with EDS mapping was found to be inaccurate only for one sample. Agreement was found between the X-ray diffraction estimates and bulk chemistry calculation. For both modal optical and SEM digitalized counting, the statistics was probably insufficient to provide accurate results. The estimates obtained from the various methods are compared with each other in the attempt to attain general indications on the precision, accuracy, advantages/disadvantages of each method.

2015 - AMS radiocarbon dating of mortar: The case study of the medieval UNESCO site of Modena [Articolo su rivista]
Carmine, Lubritto; Caroselli, Marta; Lugli, Stefano; Marzaioli, Fabio; Nonni, Sara; MARCHETTI DORI, Simona; Terrasi, Filippo
abstract

The carbon dioxide contributing to binder formation during the set of a lime mortar reflects the atmospheric 14C content at the time of construction of a building. For this reason, the 14C dating of mortars is used with increasing frequencies in archaeological and architectural research. Mortars, however, may also contain carbonaceous contaminants potentially affecting radiocarbon dating. The Centre for Isotopic Research on Cultural and Environmental heritage (CIRCE) of the Second University of Naples (SUN) has recently obtained some promising results in mortar radiocarbon dating thanks to the development of a procedure (i.e. CryoSoniC/Cryo2SoniC) aiming to eliminate exogenous C contamination that may occur in a mortar. The construction history of the UNESCO World Heritage Site of Modena (Italy) is still controversial and represents a challenging case study for the application of absolute dating methodologies for different reasons. From the point of view of 14C dating, for example, given the high percentage of carbonate aggregates composing these samples, Modena mortars represent an experimental test particularly indicative of exogenous carbon sources suppression ensuring methodology accuracy. In this paper several AMS Radiocarbon dates were carried out on lime lumps with the aim to: (i) verify procedure accuracy by a comparison of the results obtainable from lime lumps dated after different treatments (i.e. bulk lime lumps vs. CryoSoniC purified lime lumps); (ii) compare different building phases absolute chronology for the medieval UNESCO site of Modena, with that assumed by historical sources in order to assess preliminary the 14C dating feasibility for of the site. Historical temporal constraints and mortar clustering, based on petrography, have been applied to define a temporal framework of the analyzed structure. Moreover, a detailed petrographic characterization of mortars was used both as a preliminary tool for the choice of samples and to infer about the lack of accuracy (when verified) of the applied mortar 14C dating procedure.

2015 - Evoluzione sedimentaria del centro storico di Modena nel tardo Quaternario [Articolo su rivista]
Argentino, Claudio; Lugli, Stefano; MARCHETTI DORI, Simona
abstract

sondaggi eseguiti nella zona del centro storico di Modena, l’evoluzione sedimentaria del primo sottosuolo che interessa direttamente la Torre Ghirlandina e l’adiacente Duomo. Il tema centrale si sviluppa attorno al carotaggio eseguito nella primavera 2012 in prossimità dell’angolo sud-ovest della torre civica. Esso ha raggiunto la profondità di 21,30 m toccando il tetto ghiaioso appartenente all’acquifero più superficiale. È stata condotta una completa analisi dal punto di vista stratigrafico e sedimentologico, ponendo attenzione allo studio delle facies deposizionali; sono stati inoltre individuati e caratterizzati i livelli archeologici relativi al periodo romano e a quello medievale, fornendo un contributo di tipo cronologico. Elaborando una sezione stratigrafica sulla base di alcuni sondaggi che attraversano in direzione NE-SO la zona del centro storico, è stata proposta una ricostruzione paleoambientale per gli ultimi 30 m di terreno che corrispondono all’ultimo periodo deposizionale tardo quaternario. A 21 m di profondità è stato rinvenuto il tetto dell’Unità di Vignola costituita dai sedimenti grossolani che si sono deposti durante l’ultimo periodo glaciale würmiano, quando lungo tutta la fascia pedeappenninica si estendeva una piana a canali braided. Su di essa poggiano sedimenti fini di piana inondabile relativi al periodo postglaciale che caratterizza la porzione inferiore del Subsintema di Ravenna. Gli orizzonti torbosi che si rinvengono all’interno di questi depositi testimoniano uno scarso drenaggio dell’area e frequenti episodi d’impaludamento. I livelli organici cedono il posto, nell’intervallo tra -7 e -10 m, a corpi limo-sabbiosi di ventaglio di rotta. L’analisi di facies ha inoltre portato al riconoscimento di alcuni depositi riferibili ad argini naturali che indicano la presenza di canali nelle immediate vicinanze. L’insediamento romano nell’area di Modena occupa l’intervallo stratigrafico compreso tra -4 e -7 m, nel quale si registra la concentrazione di frammenti di laterizi e un livello di blocchi lapidei incontrato a 6 m di profondità in alcuni dei sondaggi studiati. La città fu sconvolta nel IV-VI secolo da ripetute alluvioni che ne causarono l’abbandono; a testimonianza di ciò rimane una spessa coltre di depositi di rotta fluviale che ricopre lo strato romano lungo tutta la sezione.

2015 - Sedimentology and composition of sands injected during the seismic crisis of May 2012 (Emilia, Italy): clues for source layer identification and liquefaction regime [Articolo su rivista]
Fontana, Daniela; Lugli, Stefano; MARCHETTI DORI, Simona; Caputo, R.; Stefani, M.
abstract

InMay 2012widespread sand blows formed along buried channels in the eastern sector of the Po Plain (Northern Italy) as a consequence of a series of seismic eventswith main shocks ofMw6.1 and 5.9. At San Carlo (Ferrara) a trench dug a few week after the earthquakes exposed sand dikes cutting through an old Reno River channel– levee system that was diverted in the 18th century and was deposited starting from the 14th century (unit A). This sequence overlies a Holocene muddy floodplain deposits and contains scattered sandy channel deposits (unit B) and a Pleistocene channel sand unit (unit C). Sands with inverse and normal grading, concave layering and vertical lamination coexisting along the dikes suggest multiple rhythmic opening and closing of the fractures that were injected and filled by a slurry of sand during the compression pulses, and emptied during the extension phase. The pulse mechanism may have lasted for several minutes and formed well stratified sand volcanoes structures that formed at the top of the fractures. Sands fromdikes and fromthe various units showwell defined compositional fields from lithoarenitic to quartz-feldspar-rich compositions. Sands from the old Reno levee and channel fill (unit A) have abundant lithic fragments derived fromthe erosion of Apennine sedimentary carbonate and terrigenous successions. Composition of the sand filling the dikes showclear affinities with sand layers of the old Reno River channel (Unit A) and clearly differ from any sand from deeper Holocene and Pleistocene layers (Unit B and C),which are richer in quartz and feldspar and poorer in sedimentary lithic fragments. Sorting related to sediment flux variations did not apparently affect the sand composition across the sedimentary structures. Textural and compositional data indicate that the liquefaction processes originated from a relatively shallow source consisting of channel sands located within Unit A at 6.8.to 7.5 m depth.

2014 - Studio dei materiali da costruzione come contributo alla storia della fabbrica [Capitolo/Saggio]
Lugli, Stefano; MARCHETTI DORI, Simona; Caroselli, Marta; Zannini, Paolo; Pallante, Paolo; Selmo, Enrico Maria
abstract

La Chiesa Parrocchiale ed il Monastero Abbaziale di San Pietro a Modena, nella sua originaria configurazione comprendente anche l’ex caserma Garibaldi, rappresentano esempi emblematici della complessa evoluzione dell’edilizia storica modenese, sia in termini di approvvigionamento delle materie prime che di evoluzione delle fasi costruttive. Tale complessità emerge dal confronto, non solo con gli illustri esempi del sito UNESCO modenese, il Duomo e la torre Ghirlandina [Lugli et al. 2009 e 2010], ma anche con il panorama edilizio dell’intera provincia modenese: il Palazzo Ducale di Sassuolo [Lugli, 1996; 2000], la Rocca di Formigine [Lugli 1997, Marchetti Dori 2005], il palazzo Comunale di Modena [Lugli, 2010] e la Rocca di Vignola [Lugli e Marchetti Dori 2006; Lugli et al. 2013]. Tra i fattori più significativi e peculiari annoveriamo il reimpiego di materiale lapideo romano mai segnalato fino ad oggi, come il marmo tasio dalla Grecia [Lugli et al. 2010] e l’utilizzo di materie prime non appartenenti alla tradizione modenese, come la pozzolana.

2013 - Composition of sands injected during the seismic crisis of May 2012 at San Carlo, Ferrara (Italy) [Relazione in Atti di Convegno]
Fontana, Daniela; Lugli, Stefano; MARCHETTI DORI, Simona; Caputo, R.; Stefani, M.
abstract

We analyzed the petrographic composition of sands injected through fractures during the seismic crisis of May 2012 along the paleo-Reno River and sands from subsurface deposits at San Carlo (Ferrara) to define their provenance and provide a contribution to the understanding of the liquefaction mechanism. The sampling of sand has been done in a trench dug immediately after the seismic event, which allowed the detailed observations of the fluvial sedimentary sequence and of sand dikes down to the depth of about 6 m (Caputo et al., 2012). We sampled also two sand horizons in the subsurface that were crossed by drillings up to the depth of 50 m. A total of 20 sand samples were analyzed: 9 from the sand dikes, 6 from the cores crossing the upper sand horizon (8-10 m depth) and the lower sand layer dating back to the uppermost Pleistocene, 1 from the paleo-channel fill of the Reno River (diverted at the end of 18th century) and 4 from the modern sands of the present-day Reno River. The sand samples were analyzed for their grain size distribution and by point-counting under transmitted light microscopy on the 0.125–0.250 mm fraction, according to the Gazzi-Dickinson method (Zuffa, 1985). At least 300 grains were point counted for each section to achieve modal composition. On the basis of the classification diagram Q+F, L, C, the sands show a defined trend from lithoarenitic to quartz-feldspar-rich composition. In particular, the sands from the modern Reno River are the most lithoarenitic. The lithoarenitic fragments derive mostly from the erosion of sedimentary rocks such as siltstone, shale and limestone. The sands filling the dikes show compositions similar to that of the modern Reno River with a slight enrichment in quartz and feldspar grains. The single sand dikes at different depths show minor, non-systematic, composition variations, in one case due to carbonate content change in another due to quartz and lithic fragments variability. The sand sample from the paleo-Reno channel fill shows a composition similar to those of the dikes and is slightly impoverished in lithic fragments compared to the modern Reno River sands. The core samples are enriched in quartz and feldspar and in some cases show a distinct content of metamorphic rock fragments, that may indicate a possible provenance from the Po River or maturation as consequence of climatic weathering that occurred during the last glacial stage (Lugli et al., 2007). The sand from the dikes fill appear clearly different from the deep sand sampled from the cores at depth, suggesting a relatively shallow source for the blowouts. Modal analyses of sands from the Modena Plain streams indicate that their provenance signal can be clearly distinguished and that the sand composition of major rivers has not varied during the last ~7 kyr (Lugli et al., 2007). It follows that provenance of older sediments buried in the floodplain can be determined by a simple comparison with modern sand composition. This indicates that we have a powerful tool to reconstruct the evolution of the drainage system that is pivotal for the recognition of potential areas prone to hazardous sand liquefaction phenomena.

2010 - I materiali da costruzione nell'interno della torre: le pietre, i mattoni, le malte, gli intonaci [Capitolo/Saggio]
Lugli, Stefano; MARCHETTI DORI, Simona; Zolli, K.; Melloni, C.; Pedrazzi, S.; Maiorano, C.
abstract

Il rilievo del paramento esterno delle torre ha permesso di individuare le fonti di approvvigionamento dei materiali lapidei e di fornire indicazioni sulle fasi costruttive (Lugli et al., 2009). Un contributo fondamentale alla lettura del monumento viene dallo studio integrato della struttura interna e dei materiali che la compongono: le pietre naturali, i mattoni le malte e gli intonaci. Il rilievo dei parametri dimensionali dei mattoni permette di individuare l’entità del reimpiego di laterizi provenienti da antichi edifici e le caratteristiche dei prodotti di nuova preparazione. L’analisi composizionale delle malte e degli intonaci permette di ottenere informazioni sulle tecniche di preparazione e la loro evoluzione nel tempo per effettuare un tentativo di datazione indiretta delle fasi costruttive. Vengono inoltre individuate le fonti di approvvigionamento delle materie prime (calce e sabbia) fornendo indicazioni indispensabili sulla preparazione di malte e intonaci da impiegare nelle operazioni di restauro.

Archeometrical analyses of Bronze Age pottery from Modena area

2008 - Pottery production in the Po valley during the Bronze age: an archaeometrical approach to the terramare society [Abstract in Atti di Convegno]
Levi, SARA TIZIANA; Cannavo', Valentina; Lugli, Stefano; MARCHETTI DORI, Simona; Vezzalini, Maria Giovanna
abstract

During the Bronze Age the Po valley was occupied by fortified villages (1650-1170 BC) which were linked by a common culture (Terramare). Their society had a complex structure and was among the most advanced in Europe. The pottery analysis project is oriented to investigate the specialization of the manufacturing process in the frame of the social organization in the Terramare. 180 pots from several sites near Modena (Pontenuovo, Gorzano, Cà dei Monesi, Montebarello and Montale), dated between Middle and Recent Bronze Age, have been analysed. 30 clays and other sediments have been sampled from different local geological units (Cardarelli et al. 2007). Ceramic and sediment samples have been investigated by: granulometry, petrography with digital image process, chemical analysis of major, minor and trace elements (WDS-XRF), X-ray powder diffraction. Some XRPD experiments were performed on raw and physico-chemical treated sediment samples (air dried, glycolated, heated at 375 and 550 °C oriented mounts) to obtain the clay minerals composition. The ceramic paste is coarse, with abundant temper (mainly calcite and grog). The common mineral composition is: quartz, albite, k-feldspar, illite (muscovite). Amphiboles, pyroxene, calcite, rutile, forsterite, hematite are present only in some samples. Chemical compositions of the pottery are quite homogenous. For the sediments the concentration of CaO is an important marker to distinguish the raw materials used for the pottery. The pots are mainly locally made, using different locals raw materials, with some differences in each site and in the selection of temper according to the functions of the pots. In the frame of this research an experimental archaeological activity has been performed in the archaeological park of Montale. Bronze Age pottery was reproduced with compatible raw materials and ancient manufacturing techniques (coils and moulds). Time and difficulty for the reproduction of each pot has been recorded and 6 different groups of pots, corresponding to increasing degrees of specialization, have been identified (Brodà et al. in press).

2007 - Alluvial sand composition as a tool to unravel the Late Quaternary sedimentation of the Modena Plain, northern Italy [Capitolo/Saggio]
Lugli, Stefano; Marchetti Dori, Simona; Fontana, Daniela
abstract

The Modena alluvial plain is located on the northern side of the northern Apenninesfold-and-thrust belt, where streams draining the chain flow toward the northeastinto the Po River. The alluvial plain is characterized by a spectacular abundanceof archaeological sites of various ages and can be considered a natural laboratory forthe reconstruction of the recent sedimentary evolution of the Po Plain. Detailed modalanalyses of modern sands of the Modena Plain streams indicate that the provenancesignal can be distinguished on the basis of key components, such as quartz, feldspar,carbonate, and lithic fragments. The compositional fields of the streams depend onthe extent of the watershed, the recycling of older fluvial sediments, and the sedimentinput from tributary streams.The modal analyses demonstrate that sand composition of the major rivers (Panaroand Secchia) has not changed during the Holocene, when sediment production,storage, and dispersal were probably dominated by colluvial aggradation in an environmentcharacterized by dense vegetation cover.In the late Pleistocene, fluvial sands were characterized by higher feldspar contentscompared with modern and Holocene sands. This feldspar abundance couldreflect a high-frequency signal in sediment supply rates linked to secular variationsof weathering processes, and it reveals the strong denudation and sediment removalconditions of the last glacial stage (15–18 ka).The implication of this study is that provenance of Holocene sediments now buriedin the floodplain can be determined by a simple comparison with modern sandcomposition. Sand composition studies may represent a useful tool to reconstruct thePleistocene-Holocene fluvial sediment supply and the evolution of human settlementsas function of climate and drainage system changes.

abstract

The Modena alluvial plain has been geologically investigated in great detail and is characterized by a spectacular abundance of archaeological sites of various age. For this reasons the area may be considered a natural laboratory for the reconstruction of the recent sedimentary evolution of the Po Plain. The alluvial plain area examined for this study has an approximate extent of 150 km2 and is located at the northern side of the Northern Apennines thrust- and fold-belt, where streams draining the chain flow toward the north-east into the Po river. Detailed modal analyses by point-counting of thin sections show that modern stream sands in the Modena plain show similar overall compositional fields, but can be discriminated on the base of key-components, such as quartz, feldspar, carbonate and lithic fragments. The study of sand sediments indicates that the compositional fields have not varied significantly since the Neolithic. The only major diagenetic process is the formation of carbonate concretions (caliche), which can be easily recognized as secondary particles during point counting of thin sections. These results indicate that the reconstruction of the recent evolution of the local drainage system is possible by comparing ancient with modern fluvial sand compositions.The drilling of numerous wells along the new high speed train tract (TAV) provided us with new insight on the sedimentary evolution of the plain through time. The samples recovered from 6 wells reaching depths up to -50 m show that the sand sediments older than 10-12 kyr, have a significant shift in composition from the modern ones. This compositional change consists in a marked overall increase of quartz and feldspar components. The compositional variations can be explained by the combination of various factors: a) significant change in the bedrock lithology through time induced by tectonics and/or change in the local drainage pattern, and b) recycling of older fluvial sediments enriched in feldspar. Because the sands older than 10-12 kyr compared to the overlaying olocenic and modern sediments are enriched in feldspar, which is considered a particularly alterable component, the compositional differentiation can not be related to effects induced to glacial-interglacial climate changes and post-depositional diagenetic processes.The considerable change in sand composition and the stratigraphy of the deposits suggest dramatic geographical, environmental and depositional variations supporting the observation that a regional unconformity separates the Late Pleistocene from the Olocene sediments.

2004 - Reconstructing the sedimentation history of an alluvial plain by sand composition investigations: the Modena case study [Relazione in Atti di Convegno]

abstract

The Modena alluvial plain area examined for this study has an approximate extent of 150 km2 and is located at the northern side of the Northern Apennines thrust- and fold-belt, where streams draining the chain flow toward the north-east into the Po river. Detailed modal analyses by point-counting in thin sections show that modern stream sands in the Modena plain show similar overall compositional fields, but can be discriminated on the base of key-components, such as quartz, feldspar, carbonate and ophiolitic fragments.The spectacular abundance of archaeological sites of various age along the main rivers allowed us to reconstruct the variation through time of the sand composition. The study of sand sediments that buried Neolithic, Iron Age, Bronze Age, Roman and Longobardian sites indicates that the compositional fields have not varied significantly since the Neolithic. These results clearly indicate that the bedrock lithology of the source area has not changed in the considered time interval and that diagenesis has not obliterated the sediment provenance signature in such a relatively short time span. The only major diagenetic process is the formation of carbonate concretions (caliche), which can be easily recognized as secondary particles during point counting of thin sections.These results indicate that the reconstruction of the recent evolution of the local drainage system is possible simply by comparing ancient with modern fluvial sand compositions.On the other, the sand sediments older than the Neolithic, and approximately older than 10.000 years, show a significant shift in composition from the modern ones, with an overall increase of quartz and feldspar components. These compositional variations can be explained by the combination of various factors: a significant change in the bedrock lithology (neotectonic effect), climate changes related to glacial-interglacial phases which induced a variation in bedrock alteration, erosion and sand deposition rates (climate effect), and the post-depositional changes that may have varied the sand composition (diagenetic effect). Further studies, now in progress, will permit a better characterization of the sediment supply through space and time, possibly allowing the reconstruction of the sand composition in the older local drainage system as response and interplay among neotectonics, climate changes and diagenesis.
