Abstract

The Qasr Al Haj Formation, comprised of alluvial fan gravels and sands with calcrete horizons, is subdivided into five members separated one from the other by surfaces of discontinuity. These surfaces, defined primarily by erosion and soil formation, can be followed northwards into the Jifarah Formation thus allowing detailed correlation of the fan-gravel deposits with the finer fluvio-aeolian sands and silts of the floodplain. Thick deposits of cemented and uncemented gravels at Wadi Ghan contain at least two horizons of basaltic lava flows. Previously reported finds of artifacts from this gravel sequence together with the possibility of radiometric dating of the lavas, may provide a much-needed chronostratigraphic framework for the Quaternary deposits of the north-west Tripolitanian region.
