An oligotypical non-marine mollusc assemblage, indicating arid and likely cold climate conditions, has been found in the sea cliff-section of Baratti Gulf (southern Tuscany). The succession is constituted by an alternation of marine, coastal and continental deposits comprised between marine isotope substage (MIS) Sc and MIS l. Eleven lithostratigraphic units have been recognised. According to previous dating work, the non-marine mollusc assemblage has been correlated to MIS 4. The global sea-level curves compared to the stratigraphic reconstruction at Baratti, suggest a first phase of subsidence followed by a very recent uplift. These data are in conflict with other neotectonic reconstruction based on MIS Se markers for this area.

Abstract

An oligotypical non-marine mollusc assemblage, indicating arid and likely cold climate conditions, has been found in the sea cliff-section of Baratti Gulf (southern Tuscany). The succession is constituted by an alternation of marine, coastal and continental deposits comprised between marine isotope substage (MIS) Sc and MIS l. Eleven lithostratigraphic units have been recognised. According to previous dating work, the non-marine mollusc assemblage has been correlated to MIS 4. The global sea-level curves compared to the stratigraphic reconstruction at Baratti, suggest a first phase of subsidence followed by a very recent uplift. These data are in conflict with other neotectonic reconstruction based on MIS Se markers for this area.
