Abstract:Taoshan uranium orefield is located in the central Jiangxi province, where the fractures, both metallotectonic also oreconservative, had developed extensively, of which Taoshan fault, with NEstriking, SEdipping at 65°~70° , rightlateral slip, developed in neotectonism period, is an oreconservative one, not only their southeast block downgliding, but Jiaolian fault characteristics. Taoshan fault causes the Umineralization shell in NW and NEdipping, so resulting in weak erosion in the end dumping, especially in its northeast part. For this reason, there are good oreprotecting conditions and more prospecting potential in those region and an important significance for uranium ore exploring.
