Repeated Tethyan influences in the Early Campanian to Middle Late Maastrichtian successions of Folx-Les-Caves and Orp-Le-Petit

A preliminary study of the macrofossils (belemnites in particular), benthic forams and ostracodes in the Late Cretaceous chalk deposits at Folx-les-Caves and Orp-le-Petit (eastern Brabant Massif, Belgium) suggests that the sequence at Folx-les-Caves is of early Campanian (post lingua/quadrata Zone) age. The «craie blanche» and the «tuffeau jaunâtre» at Orp-le-Petit were deposited during the late Campanian and middle late Maastrichtian, respectively.The sedimentation of these chalks under shallow to very shallow subtidal conditions was temporarily interrupted by periods of emergence (conglomera...
