Salt diapir outcropping in Crotone Basin
The Crotone-Rossano Basins are the onshore equivalents of the larger Neogene/Quaternay Ionian basin, developed in the frame of the estward migration of the Mesomediterranean microplate, which led to the subduction of the Ionian lithosphere and the spreading of the Tyrrhenian back-arc Basin (Central Mediterranean). The fieldtrip focuses on the main features of the Neogene basin-fill successions and their close relations with synsedimentary tectonics and salt tectonics. The basal transgression consists of a siliciclastic wedge passing from fluvial strata to deep-marine turbidites, followed by a thick evaporite sequence, including sulphate and halite salts(often forming diapirs) , recording the Messinian salinity crisis. Moreover, late Messinian compressional tectonics controls the basinal architecture leading to regional unconformities whereas post-Messinian sedimentation is mainly controlled by extensional tectonics and sea-level changes.
Lamezia – Policastro – Casabona – Cirò – Belvedere di Spinello – Roma
The fieldtrip consists of short walks along easy paths, for reaching outcrops. Expected weather conditions are: daily temperature between 25°-30°, generally sunny and dry, with possible short heavy showers.
