Popis: With the aim to evaluate the hydrocarbon potential of the Messinian Tripoli Formation widely outcropping in the Sicily structural evaporitic basins, nineteen field sections sited mostly in Central Southern Sicily have been investigated in a cooperation program with ENI. Many of these basins are part of the Gela accretionary wedge, the highest and more recent tectonic element of the Sicily Fold and Thrust Belt. The study evidentiates the tectonic involvement of the several Tripoli-Evaporites sections, originally deposited in an area now occupied by the Tyrrhenian Sea. A restoration of the surface and subsurface setting images the Tripoli as deformed in large, buried asymmetrical synclines and surface tight anticlines with limbs eroded in outcrop. With reference to the well-known Tripoli chronology (nine bioevents constrained by cyclostratigraphy), each section has been assigned (referred) to a well defined biostratigraphic and chronologic interval. On the ground of the micropaleontological associations the palaeoenvironmental evolution has been restored in order to recognize the occurrence of openly marine to restricted domains. Finally geochemical analyses helped to recognize and evaluate an unexpected hydrocarbon potential for the exploration of the Tripoli Formation in Sicily.
