Description and itinerary
Aim of the field trip is to discuss the south Apennines Quaternary foredeep evolution showing stratigraphic and sedimentologic features of undeformed to tectonized successions cropping out in some selected areas of Puglia and Basilicata (southern Italy).

The first day (6 September 2024), moving from Bari to Minervino, we will cross from E to W the Apulian Foreland looking out the Bradanic Trough (the Quaternary south Apennines foreland-basin). We will observe the response of temperate carbonate systems unable to match with the subsidence in the outer margin of the foreland basin. Then, we will move to Genzano di Lucania to observe coarse-grained siliciclastic coastal deposits representing the oldest undeformed deposits of the top of the Bradanic Trough (end of shortening [?], and response of coastal systems to the first stage of definitive filling of the foreland basin). The last stop is in Acerenza, where we will discuss about sedimentology and stratigraphy of Quaternary tide-influenced shallow-marine systems developed on moving thrusts (wedge-top area). In the late afternoon we will transfer to Potenza.
The second day (7 September 2024), we will observe in the surrounding of Potenza some coarse-grained deltas and their stacking patterns reflecting various morpho-tectonic conditions proper of a satellite basin of the wider wedge-top system. Then, we will first visit Tricarico, to observe mixed deposits representing tide-influenced  systems coeval to in Acerenza, second Calciano, to see the big fan delta developed at the front of the chain when the Genzano succession aggraded in the north of the foreland basin and, finally, Grassano, where the village was built "inside" and on a very small Gilbert type delta ("I Cinti" locality). A panoramic view from the chain front to the Ionian Sea will lead us to discuss about the middle-late Quaternary uplift-related staircase of terraced marine deposits developed in the hinterland of the Taranto Gulf. In the afternoon we will return to Bari.
