The gypsiferous carbonate sequence occurs as a tectonic slice with no observed stratigraphic contacts. It is structurally overlain by a Mesozoic-Early Tertiary turbiditic-olistostromal unit, Late Triassic–Liassic dolomitic limestone and Cretaceous ophiolite. The gypsiferous sequence is characterized by intercalation of white–grey massive gypsum and black dolomitic limestone. The gypsum at the outcrops seems to be secondary formed by the hydration of precursor anhydrite, and shows typical porphyroblastic and alabastrine textures with corroded anhydrite relics.
The deformation affecting the Late Triassic gypsum-bearing sequence has been grouped under two major phases. First, thrusting with intense folding and imbrication showing compressional deformation with top-to-the-NE sense of shear. This deformation is widespread in the Kalebox11f;azı formation and the structurally overlying dolomitic Gereme formation. Second, the formation of E-W trending high-angle normal faults and N-trending strike-slip faults, which control the present day structural frame of the region.
