In the Kerman — Ravar area and its northern extension to Nabibandan and Tabas areas, there are a number of evaporitic strata and salt diapirs, belonging to Cambrian, Silurian, Devonian, late Jurassic and early Cretaceous. But their exact stratigraphic position, in tectonically disturbed areas and along main fault-lines is often unclear.
The aim of the present study is to determine the exact stratographic position of the middle and upper Jurassic sedimentary sequences and evaporitic strata in the Ravar and Kerman areas. Based on previous studies and personal observations and in accordance with Huckriede et a!. (1962), it is proposed to apply “Ravar Formation”, to the late Jurassic evaporitic strata lying upon the “Pectinid Limestone” and below a thick clastic and pink sequence at the base of the Barremian-Aptian Rudist-Orbitolina limestones. For the older (early Cambrian) evaporitic strata, analogous to the “Hormoz Formation” of Southwest Iran, the name “Desu Formation” is proposed. The name “Bidou Formation” should be applied only to the red and clastic sequence lying upon the Hojedk Formation and Cretaceous clastic sequences.
