ارزیابی ناحیه ای و بررسی مقدماتی زمین شناختی، ساختاری و فلززایی حوضه دشت کویر و احتمال تشکیل کانه زایی اورانیوم نوع رسوبی سطحی در آن

Great Kavir basin is the largest inner basin in Iran  that extended about ۹۰۰۰۰ km۲. 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 margent Great Kavir basin, are Arosan, Irekan and Mohammad Abad. Similar geological – structural conditions for uranium mineralization is possible in the margent of Great Kavir basin.
