“Dolomites and dolomites” in Mesozoic platform carbonates of the Southern Apennines: Geometric distribution, petrography and geochemistry

Abstract

A multidisciplinary study of the dolomitized bodies present among the Late Triassic to Late Cretaceous carbonate deposits of the Monti Lattari belt (Southern Apennines of Italy) compares the different dolomitization styles present within this succession of these Mesozoic platform carbonates and furnishes an overview of their formative genetic models. The revealing traces of the diverse modes of diagenesis in this region include both surface and subsurface mechanisms, utilizing: a geometric reconstruction of the dolomitized bodies, an integrated facies and petrographic analysis of the components, and a geochemical characterization of the sediments including detailed mineralogy and associated stable isotope values
