Abstract

The fieldtrip corresponds to a transect across the northeastern to the western Calabria. The two-days fieldtripillustrates the Miocene to Quaternary tectono-stratigraphic features of the two distinctive Calabria margins.Sedimentary architecture and tectonic activity are testified in the infill of basins. Some structural features ofthe Calabrian Neogene basins cropping out in the northern sector of Calabria are exposed. The first dayconcerns the Neogene structural and stratigraphic evolution of the eastern Calabria margin in the peri-Ionianpiedmont. The fieldtrip focus on the effects of the tectonic deformation during Neogene sedimentation in theRossano and Crotone basins. Typical foreland-basins characterized by clastic sediments were derived fromuplifted fold-thrust belts exposing sedimentary, metasedimentary and plutonic source rocks. The entirestratigraphic, structural and compositional data set are interpreted using new general models of sequentialevolution of foreland basin systems. The asymmetric fold growths, are also responsible of the progressiveunconformities observed in the Rossano and Crotone basins. Facies associations record strong erosion andcannibalization processes of the lower stratigraphic unit, whereas a marine clastic sedimentation persisted inthe Cirò basin. The exposed stratigraphic and structural architecture are related to the offshore borehole andseismic stratigraphy, suggesting the presence of structural highs, interpreted as thrust and folds and havingthe main onshore evidence in the “Cariati Nappe”. During the fieldtrip, some outcrops of the margin flexureand related progressive unconformities in the succession and major backthrust can be looked. Pliocene-Quaternary sedimentary architecture and tectonic activity will be observed in the Crotone basin. In the secondday, the fieldtrip is mainly concentrated on the western margin of Coastal Chain along the Amantea basin. Inthis day other stops in the Crati basin on temporal and spatial distribution of transtensional and transpressionalfaulting involving the metamorphic units of the Coastal Chain and the Pliocene-Pleistocene deposits can beobserved. To the north of the Amantea village, the marginal facies of the infill outcrop and the basin marginhas been offset along the major fault zone. To the south of the Amantea village, tectono-stratigraphicassemblage of the second sequence and Tortonian growth faults can be observed. Panoramic view of thewestern Coastal Range piedmont zone will be shown during the Stop in the Fiumefreddo Bruzio village.
