Taoshan uranium orefield is located in the central Jiangxi province, where the fractures, both metallotectonic also oreconservative, had developed extensively, of which Taoshan fault, with NEstriking, SEdipping at 65°~70° , rightlateral slip, developed in neotectonism period, is an oreconservative one, not only their southeast block downgliding, but Jiaolian fault characteristics. Taoshan fault causes the Umineralization shell in NW and NEdipping, so resulting in weak erosion in the end dumping, especially in its northeast part. For this reason, there are good oreprotecting conditions and more prospecting potential in those region and an important significance for uranium ore exploring.
