CARATTERI PETROGRAFICI E PROVENIENZA DELLE ARENARIE TORBIDITICHE MIOCENICHE DELL'APPENNINO CENTRALE

Abstract

A regional petrographic study of the Miocene turbidite sandstones of the centra! Apennines has been focused on the siliciclastic detritus utilizing three ratios: Q/Q + F and Mc/M, have been used and binary correlations of these parameters show that: 1) the sandstones of the Marnoso-Arenacea s.s. are charac­terized by a northern Alpine supply, mainly derived from metamorphic rocks and subordinately from granitic rocks; [...]
