Abstract
The Sirte basin was tectonically developed in the late Miocene time as a southerly extension of the Tethys geosyncline. By the advent of the Miocene period the embayment was largely infilled by carbonate and siliciclastic deposits through marine transgression (Selley, 1971, 1985). The Miocene deposits situated in Al Khums area, North Western Sirte basin, are represented basically by transgressive – regressive marine carbonate – siliciclastic deposits this variation is controlled mainly by the degree of erosion and topography conditions of the preexisted underlying Upper Cretaceous rocks.The study area is located in North Western Libya at Al Khums between Lat. 32o – 33o N and Long. 13o 13’ – 15o 00’ E. The Miocene sediments cover a total area of 3000 Km2 (Figs.1&1.2). Al Khums City precisely located on the coastal strip of Libya on the Mediterranean sea and far west of the city of Misurata, 100 Km east of the capital Tripoli.120 Km.
