The Plio-Pleistocene successions exposed along the opposite edges of the southern Apennines foredeep basin record marginal-marine settings where waves and weak tidal currents interplayed with different degrees. Along the chain-edge of the basin, these conditions were governed by local geomorphological elements, such as coastal sheltering, promontories, presence of tectonic highs and local inlets.
Mixed, terrigenous-bioclastic deposits accumulated in a variety of shallow-marine environments, reproducing scales of mixing between the antithetic clastic components and a wide spectrum of degrees of segregation. These elements are used to reconstruct the interplay between the primary hydrodynamic controls in such settings and indicate how sensitive shallow-water mixed systems are in recording environmental conditions impacting on the sedimentation. Along the foreland-edge of the basin, wave dominated mixed carbonate system (terrigenous-bioclastic) developed along rocky gentle slopes of a tectonic high, leading to seismic-scale back-stepping clinoforms. The main goals of this field trip are: (i) to familiarize with the basic elements observable in mixed sediments and referable to wave- vs. tide-influenced structures; (ii) to detect large-scale (seismic- to sub-seismic) features of infralittoral prograding wedges.
The trip will start from and return to Matera during both the days of excursion. All the places are located 1-2 h driving, in easily accessible places with no relevant difficulty.
