The Sarvak Formation, which hosts the Daresard deposit, represents an Upper Cretaceous (Cenomanian–Turonian) carbonate succession within the Zagros Fold–Thrust Belt (ZFTB) of southwestern Iran, deposited in a shallow-marine carbonate ramp environment along the Neo-Tethyan margin. The Late Cretaceous tectonic evolution of the Zagros Basin, driven by the incipient closure of the Neo-Tethys Ocean and the onset of the Zagros orogeny, induced profound paleogeographic modifications during the late Cenomanian to Santonian interval. These tectonic processes resulted in regional-scale uplift events and the development of significant stratigraphic hiatuses (erosional surfaces and non-depositional intervals). The bauxite deposits in the study area occur as 18–24 m thick, lens-shaped ores within karstic depressions of the Sarvak Formation (Cenomanian–Turonian), primarily along the limbs of NW–SE-trending anticlines parallel to the Zagros Fold–Thrust Belt, notably the Kuhe-Nil anticline (65 km long, 4 km wide), which hosts the Daresard deposit 30 km east of Dehdasht, SW Iran. The Daresard bauxite profile comprises: (I) a basal 1–3 m breccia bauxite with bauxitic cement and rounded fragments overlying argillaceous limestone; (II) an 11 m thick oolitic-pisolitic bauxite ore with yellow pods in a red matrix, sparse ooids, and 0.5–1 m spheroidal boulders from onion-skin weathering; and (III) a 5–7 m bleached horizon of light-colored boehmite oolites showing deferrification, abruptly capping the sequence.
