Jurassic foraminifers from the Mazagan Plateau, Deep Sea Drilling Project Site 547, Leg 79, off Morocco.

Abstract

The first marine incursion of the incipient North Atlantic Ocean is recorded in the uppermost Triassic to Lower Jurassic sequence. A lithologic change from continental red beds below to slope breccias and hemipelagic carbonates above indicates that a carbonate ramp was probably established by Sinemurian time along the Moroccan continental margin and that subsidence in the adjacent basin was rapid in the early phases of continental rift.-from Author
