Abstract

In the Tarquinia basin, two Pliocene sedimentary cycles are developed on the substraum consisting of the Late Cretaceous-Eocene Tolfa Formation (outer Ligurid unit), and are separated by a 0,3-0,4 Ma hiatus along an unconformity surface. The first cycle has an Early Pliocene-Early Middle Pliocene age and consists of shelf mudstones ; the later has a Middle Pliocene age and consists of the Tarquinia Calcarenite and its heteropic sands. The comprehensive composition of biocalcarenites and hybrid arenites confirms that sedimentation of the Tarquinia Calcarenite succession was basically intrabasinal, whilst the extrabasinal supply was very scarce. - (NF)
