TL;DR: The Vazzio Oligocene Formation as mentioned in this paper is composed of a continental sedimentary sequence, mainly conglomerate, with a thickness of 250 to 300 m. Pollinic association and mammal data have been used to date the formation.
Abstract: Evidence of Oligocene deposits was for the first time described in Corsica (near Ajaccio) within the Vazzio Formation. The succession is composed of a continental sedimentary sequence, mainly conglomerate, with a thickness of 250 to 300 m. Such conglomerates were deposited in torrential and lacustrine environments. Pollinic association and mammal data date the formation from Late Oligocene age (MP 29). The Vazzio Oligocene formation was deposited in a half-graben upon Hercynian granites. Within the Corsica-Sardinia block, the Vazzio Formation can be considered as an equivalent of the Ussana Formation of Sardinia. A Late-Oligocene palaeogeographic reconstruction is attempted, prior to the rotation of the Corsica-Sardinia block.
