Regional Evaluation and Primary Geological, Structural and Metallogenical Research of Great Kavir Basin as View of Possibility Formation of Sedimentary- Surficial Uranium Mineralization

Great Kavir basin is the largest inner basin in Iran that extended about 90000 km-2. This basin is situated in the centre of Iran , to the south from Alborz mountain range and elongated in the sub latitudinal trend and its construction is asymmetric. The basin cover consists generally of complicated sequence of continental - marine Oligocene - Miocene molasses. According to drainage systems conditions, molassoid cycles, alluvial, alluvial - deltaic and lacustrine sediments, climate, morphological conditions and metallogenic and structural features, Great Kavir depression generally is favorable for exogenic and surficial uranium deposits (vally - fill, flood plain, deltaic and playa). Uranium occurrences that are Known in the southern and north eastern part of the margcnt Great Kavir basin, arc Arosan, Irekan and Mohammad Abad. Similar geological - structural conditions for uranium mineralization is possible in the margcnt of Great Kavir basin.
