Potential Map Ping and Regional Geochemical Exploration of Uranium by Using Tracers in Esfordi 1:100,000 Sheet

According to Atomic Energy Organization of Iran (AEOI) Uranium exploration program in Central Iran, Esfordi 1:100,000 sheet which is located in Yazd province, between Bafq & Behabad cities was prospected. The analysis result of the stream sediment samples which were collected by the Geography Society of Iran (GSI) have been used for radioactive resources of this area. Due to lacking of uranium, thorium and Rare Earth Elements (REE) analysis data, the uranium tracers have been used. The data processing, i.e. normalization, univariate and multivariate analysis were studied and ultimately, anomalies maps were prepared. Three uranium potential areas were introduced. These areas include marl and conglomerate sequence in North-west of region, south of Zarigan granite and sandstone sequence with aplites between Esfordi mine and Kooshk mine. Thus, Esfordi sheet is important as a sediment hosted uranium deposit.
