Abstract

Lower Jurassic shallow water carbonate successions from the Tonezza area (Vicenza, northeastern area) were analysed in terms of lithology, biotic components, facies. In these successions black shales horizon occur. These are characterised by high organic contetn and by a unique bivalve and ostracod fauna. The facies analysis and the palaeoecological analysis suggest a oligohaline, non-marine laggonal settings for these benthic communities.
