The lithostratigraphy and petrography of the Ras Malaab Group were investigated in order to define the physiography and structure of the depositional basin. The Ras Malaab Group consists, from the top, of the Zeit, South Gharib and Belayim Formations. The basal Belayim Formation consists of carbonate barrier (reefal, lagoonal and marine tidal‐flat carbonates, located from east to west respectively in the basin. Thus. reefal limestones and evaporites are associated within the succession of the Belayim Formation. The overlying South Gharib Formation is composed of thick evaporite sediments that were deposited in a restricted, subsiding salina basin. Intense subsidence in the western part of the basin is related to faulting. The Zeit Formation consists of evaporites and fine clastics derived from surrounding land‐masses. The Zeit sequence indicates relatively deeper, semi‐restricted, lagoonal conditions.
