The Dagh-e-Sorkh playa is a closed basin in central Iran. The sediments of this playa were studied for sedimentologic and geomorphologic characteristics, the interaction of sedimentation mode of a terminal ephemeral fluvial-fan system and adjacent lacustrine/aeolian sediments in the area. Evaporite minerals including calcite, gypsum and halite were the most dominant minerals. The two main types (pediment and playa type) and few sub-types facies were identified. Based on the surface and subsurface study, the area was zoned and sedimentary–stratigraphic column for each zone was interpreted and six zones were characterized. These data clearly show that different conditions are dominant for the deposition of sediment and vertical changes in sedimentary facies around the area.
