中文摘要:
      相山铀矿田是迄今为止国内最大的火山岩型铀矿田,其内铀矿化与断裂构造紧密相连。相山西部已探明12个矿床,在平面上多数分布于NE、NW向构造围成的菱形断块内,少数处于NE、NW向构造交汇部位及附近。菱形断块自西向东分别为:河元背、居隆庵、芙竹坪3个菱形断块。河元背菱形断块内发现4个矿床,有湖港、河元背和牛头山铀矿床以及近年来探明的河元背8号带矿床,断块内构造发育,主要有NE向、NNW向、近SN向构造共同控制着断块内铀矿化的产出。铀矿体赋存于断裂构造破碎带或裂隙带中。显然,构造对河元背菱形断块内铀矿化具控制作用。
英文摘要:
      Xiangshan uranium ore field is the largest volcanic uranium ore field in China, and its uranium mineralization is closely related to fracture structure. Twelve deposits have been discovered in the western region. They are mainly distributed in lozenge shaped block which is caused by the NE and NW board structure, some in the positions of NE and NW fracture’s inter junction and nearby. The lozenge shaped blocks are Heyuanbei, Julongan and Fuzuping respectively from west to east. Heyuanbei lozenge shaped block has developed uranium deposits of Hugang, Heyuanbei, Niutoushan and No. 8th belt deposit discovered in recent years. The structure development in the fault block mainly includes the NE, NNW and near SN structures to jointly control the output of uranium mineralization in the lozenge shaped blocks, and uranium ore bodies are found in fault fracture zone or fissure zone. T Obviously, The fracture structure control the uranium mineralization in Heyuanbei lozenge shaped block.
