Integrated biostratigraphy across the Aalenian/Bajocian boundary of the Central High Atlas, Morocco

Driss SADKI

Abstract


This work presents an integrated biostratigraphic study across the Aalenian/Bajocian boundary of the Central High Atlas of Morocco. The data that are the basis for this study were obtained from the region of Rich that is located in the center of the basin of the Moroccan High Atlas. This region presents a thick Aalenian–Bajocian succession with continuous marine sedimentation, which offers a rich and varied fauna whose analysis enables the compilation of an integrated biostratigraphy based on the different paleontological groups: ammonites, belemnites, brachiopods, bivalves, gastropods, calcareous nannofossils, foraminifera and ostracods.
