Abstract

The mixed siliciclastic-carbonate successions of Early Mesozoic age exposed in the Pseudoverrucano tectonic units, along the coast of southern Tuscany (Montebrandoli and Punta delle Rocchette, Early Liassic) and in the Monti dell’Uccellina (Porticciolo di Cala di Forno and Salto del Cervo, Late Triassic) are characterized by fossil assemblages suggesting a close relationship with the coeval, mainly carbonate successions of the "Tuscan Series" while the depositional features are completely different. The peculiar vertical evolution of the Pseudoverrucano facies suggests that the episodic input of siliciclastic materials was connected with storm events most probably triggered by tectonic pulses. The depositional features and fossil content of the mixed siliciclastic-carbonate Pseudoverrucano successions argues for a coastal sedimentation on narrow shelves delimited by active, fault-bounded highs, representing the landward extension of the epicontinental/pericontinental pelagic basins that from late Triassic in a regime of continental rifting, developed on the east-facing shelf of central Pangea. - (NF)
