The Nuwaifa bauxite Formation is divided into two major groups of lithofacies according to lithology. The first group is the allochthonous lithofacies (Table 1), formed mainly from clastic sediments transported during several sedimentary cycles; three lithofacies have been identified as sandstone (Chanel fill), sandy or silty claystone (flood plain), and claystone (basin of karst) lithofacies.
