The Djebel Melah (Salt Mountain) of El Outaya, north of Biskra on the Tertiary plain in the Saharian Atlas, has outcrops of evaporite-bearing clays. Halite forms the main mass of the mountain; intercalations of pink marl, which include crystals of anhydrite, aragonite, dolomite, bipyramidal quartz, and hematite, are present near the northern border. The Triassic saline clay contains blocks of black Hettangian limestone and ophites. A diapiric injection of gypsum and halite into the Senonian limestone is apparently related to a Pliocene northwest-trending flexure.
