No.207 uranium deposit is located in the west of Longshoushan metallogenic belt,The district has undergone multi-period geological structure events and strong magmatic activities.The major outcrops are downer Proterozoic metamorphic rocks named Longshoushan group and Zhongtiaoian granite.Regional structrual line in this area is north west—south east.Uranium mineralization in this ore deposit is mainly controlled by granite body and fracture structures.Uranium mineralization possesses obvious poly-stage characters.Uranium mineralization age is 1750Ma,indicating a rather little time difference between the ore and the rock.The ore deposit possesses the common characteristics of the granite type uranium deposits.The author studied the regional geological setting and metallogenic characteristics of No.207 uranium deposit and analyzed the sources of ore substances and ore fluids and channels for transport of ore substances,and on that basis,a uranium metallogenic model for No.207 uranium deposit was constructed.Uranium metallogenesis of the ore deposit took place in a specific temporal－spatial domain controlled by the regional geological setting ; regional uranium－rich strata provided substances for metallogenesis and ore fluids derived from magmatic water,magma and postmagmatic hydrothermal fluids were carriers of uranium transport.The uranium metallogenic model emphasizes that the formation process of granite was a process of ore substance concentration.
