| 摘 要： | 桃山铀矿田位于江西省中部，断裂构造发育，既有成矿构造，也有保矿构造，其中斜贯桃山矿田的桃山断裂即是一保矿构造，它形成于车免近时期，走向北东，倾向南东，右行正断，并具铰链断层性质，上盘地块掀斜下落，致使上盘成矿壳层向NW和NE倾斜，由于倾末端的侵蚀深度较小，保矿条件较好，加强这些地带的铀矿勘查和评价具有重要意义。

| Abstract: | 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. |
