A contribution to the geology of the Bahariya Oasis,Western Desert,Egypt

Size and mineral analysis of the Upper Cretaceous clastics of the Bahariya Oasis indicate moderately well sorted, coarse skeewed and mesokurtic sediments. These sediments were most probably derived from mixed igneous, metamorphic and sedimentary sources, under conditions of low rainfall and poor drainage interfered by high rainfall periods.The shape of quartz grains and occurrence of stable and less stable minerals prove a short distance, saltation to graded suspension transportation of these sediments.Probably coastal plain, interfered by fresh water conditions had prevailed during the accumulation of these sediments, i.e. fluviomarine environment.
