Quaternary Evolution of Coastal Plain in Response to Sea-Level Changes: Example from South-East Sicily (Southern Italy)

During a cycle of sea-level variation, coastal environments develop in different position the continental shelf following seaward and landward shift coastline. They vary widely character, reflecting wide range process-regimes that are brought about during stages variations. Within this scenario, morphology shelves, mainly resulting from combined effect tectonic activity eustatism, plays an important role controlling features preservation environments. Coastal deposits formed along shelves past, changes, consist discontinuous thin depositional bodies, thus their reconstruction can be best carried out through interpretation high-resolution seismic data. Such research approach is adopted present study to investigate portion southernmost sector SE Sicily, offshore Marzamemi village (Syracuse). The “Sparker” profiles allowed us reconstruct evolution alluvial lagoonal environments, established on substratum Pliocene or more ancient marine deposits, with detection several units unconformity surfaces, which have been related alternating sedimentation erosional processes, depicting change framework glacial-interglacial phases, late Pleistocene onward.
