Abstract

The southern Apennines preserves deep-marine clastic wedges with contrasting and mixed petrofacies, that include distinctive sandstone suites, of dominantly turbidite systems accommodated within the southern Apennines foreland region: I quartzarenite suite of the Numidian Sandstone, Aquitanian-Burdigalian in age, II Quartzolithic sandstone suite of the Corleto Perticara Formation, Burdigalian in age, III quartzofeldspatholitic sandstone suite of the Cilento Group (San Mauro and Albidona Formations), Langhian-to-early Tortonian in age, IV quartzofeldspathic suite of the Gorgoglione Formation, Serravallian-to-Tortonian in age, and the V arkose sandstone suite of the Oriolo, Nocara, Castelvetere Formations, late Tortonian-early Messinian in age. Here, we investigate the post-depositional history, the main diagenetic events, and their influence on the evolution of the petrophysical features in a turbiditic foreland region system. The studied formations are characterized by porosity and permeability values that commonly follow the sandstone detrital modes, and the effect of compaction and cementation that reduce the intergranular volume during diagenesis. The correspondence analysis was applied to both petrographic and petrophysical datasets to explore the relationships between groups of variables, and the results are shown on biplots in a two-dimensional space, to refine a petrophysical model of potential reservoirs in foreland clastic wedges setting of the southern Apennines.
