This guidebook to Pleistocene sediments exposed in eastern central Italy has been prepared for the PRE-3 geological field trip accompanying the XXI INQUA Congress held in Rome, Italy, in July 2023.

The Central Periadriatic Basin stretches along the Marche and Abruzzo regions and is an excellent example of an evolving mountain chain and associated deep-marine to fluvial-alluvial foredeep and wedge-top basin system. By integrating surface and subsurface datasets, this field trip affords a fine west to east transect through the Pleistocene basin-fill in southern Marche, where exposures allow a close examination of sedimentary facies and architecture of depositional systems. The basin fill succession includes coarse-grained submarine canyon-fills encased in slope mudstones, mixed beachface-shoreface conglomerates and sandstones, and alternating conglomerate and mudstone bodies interpreted as fluvial-channel and floodplain deposits, respectively. The analysis of facies architecture and discontinuity surfaces will allow the attendees to understand the relative role of sea-level changes, sediment supply, and thrust front propagation inside the foreland basins system as several factors controlling the stratigraphic record.

Abstract

This guidebook to Pleistocene sediments exposed in eastern central Italy has been prepared for the PRE-3 geological field trip accompanying the XXI INQUA Congress held in Rome, Italy, in July 2023. It is designed to provide an overview of the sedimentological features, stratigraphic architecture and basin evolutionary steps during the Pleistocene of the central portion of the Periadriatic basin (Central Periadriatic Basin), a N-S oriented foreland basin system associated to the Central Apennine Outer Orogenic Wedge. The Central Periadriatic Basin stretches along the Marche and Abruzzo regions and is an excellent example of an evolving mountain chain and associated deep-marine to fluvial-alluvial foredeep and wedge-top basin system. By integrating surface and subsurface datasets, this field trip affords a fine west to east transect through the Pleistocene basin-fill in southern Marche, where exposures allow a close examination of sedimentary facies and architecture of depositional systems. The basin fill succession includes coarse-grained submarine canyon-fills encased in slope mudstones, mixed beachface-shoreface conglomerates and sandstones, and alternating conglomerate and mudstone bodies interpreted as fluvial-channel and floodplain deposits, respectively. The analysis of facies architecture and discontinuity surfaces will allow the attendees to understand the relative role of sea-level changes, sediment supply, and thrust front propagation inside the foreland basins system as several factors controlling the stratigraphic record.
