Abstract

The Burano Formation, consisting of evaporitic-dolomitic horizons, has been encountered partly in boreholes and partly as scattered outcrops in Boccheggiano and southern Tuscany areas. In the boreholes, this unit overlies the Filladi di Boccheggiano Formation and is overlain by the Calcare Cavernoso or the Ligurian Nappe. In outcrops, this evaporitic-dolomitic sequence, following sulphate dissolution, is represented by the brecciated unit known as Calcare Cavernoso. Sedimentological, micropaleontological and stratigraphical analyses have a1lowed to assign a Carnian-Norian age to the Burano Formation in southern Tuscany. The depositional paleoenvironment corresponds to a sabkha complex bordering a more or less restricted marine water body. The paleogeographic setting of the Triassic southern Tuscany is located between the La Spezia and Umbria domains. Following a detailed study, the contact between the Filladi di Boccheggiano and the Burano Formation is shown to be stratigraphic and gradual.
