Abstract
Publisher Summary This chapter describes the stratigraphy and tectonic evolution of Sirte basin of Libya. The Sirte basin is a major sedimentary basin that extends southward from the Gulf of Sirte in central Libya. It is found that, unlike the basins of southern Libya and Algeria, there is little surface expression of the Sirte basin. It lies beneath vast sarir gravel plains with occasional sand seas and escarpments. The existence of the Sirte basin was unknown until gravity and magnetic surveys were carried out in the late nineteen-fifties, as a part of the quest for petroleum. The oldest rocks encountered above the Sirte basin unconformity are of Cenomanian age. This is, thus, taken as the date for the collapse of the Tibesti-Sirte arch. It is found that these dates come from the wells drilled on the crest of structural highs. The Sirte basin is extensively dissected by the complex of Late Miocene deep steep-sided sand-filled channels that drained northward into the Gulf of Sirte.
