Abstract

The paper presenis a detailed stratigraphical analysis coupled with the compositional study of two mixed carbonate-siliciclastictu rbidite successionso f Paleocene-Eocenea se in the northern Apennines: the Monte Soornoand Marne rosate di Tizzano formations. The bed by bed measure of more than 1000m of the M. Sporno succession and of significant portions of the basal (Bersatico) and upper (Castelmozzano) members of the Màrne rosate Fm has allowed the recognition of the different types of turbidite beds and hemipelagites which alternate in the successionsand an estimate of their frequency and cumulative thickness. Turbidites vary from thin-bedded arenitic siliciclasticbeds to carbonate and mixed megabeds, and show a remarkable internal variability. The M. Sporno Fm consists of a monotonous successiono iturbidites and hemipelagites,without evident verrical trend except for a slight increase of pelitic lithologies up section. Otherwise, the lower and upper members of the Marne rosate Fm are characterized by a distinct stratigraphic framework. The lower Bersatico Member is dominated by carbonate and mixedbeds and megabedsa nd showsa broad similarity with the M. Sporno succession The upper Castelmozzano memberis made chiefly of thin-bedded arenitic siliciclastic beds, and carbonate beds are subordinate. The sediment is suppliedto the basin by a number of sources, primarily inmabasinal pelagic and shelfal areas which produced the abundantbiogenic carbonate detritus
