Summary: The deposits of the Otjomongwa pan, southwestern Kalahari, Namibia, contain halite, thernadite and minor amounts of calcium-bearing sulfate minerals. The deposits show vertical variations in salt content, evaporite mineralogy were formed by evaporation of groundwater, within a groundmass of lacustrine deposits that did not contain synsedimentary evaporites. Lateral variations in total salt content are related to the direction of groundwater flow during a period with high groundwater levels following the end of lacustrine sedimentation in the pan basin. This was followed by a period without groundwater influence that continues to the present. During this stage, leaching by rainwater occured, resulting in changes in evapotite mineralogy, morphology and distribution
