4). Basinal marls pass south into skeletal shoal sands. These separated the open sea from a lagoon, that passed landwards, via tidal flats, into an alluvial coastal plain which supported a rich fauna indicative of savannah conditions (Selley, 1969; EI-Hawat, 1980). The Sirte basin is extensively dissected by a complex of Late Miocene deep steep-sided sandfilled channels that drained northwards into the Gulf of Sirte. This feature, termed the Sahabi Channel, provided early impressive evidence to support the argument for the Messinian salinity crisis of the Mediterranean (Barr and Walker, 1972).
