| 摘 要： | 响溪金矿区周边出露黄茅园复式岩体、中华山岩体和其它隐伏岩体等,岩浆多期次活动。岩体与周边围岩金丰度值高,NE向张扭性断层贯穿岩体与围岩,围岩中发育NW向劈理化带是外接触带矿床的容矿构造。建议加强岩体及贯穿岩体的NE向断层的含矿性研究是寻找内接触带矿床的突破口,外接触带矿床主要需加强平行劈理化带的找矿,已知矿区要加强走向上的浅部控制。

| Abstract: | Huangmaoyuan complex massifs,Zhonghuashan rock bodies and other concealed rock bodies out-crop and signs of multiple phase activities of magma occur in the peripheral area of Xiangxi gold mining area. The gold abundance value is high in rock bodies and peripheral wall rocks,and NE-trending transtensional fault penetrates through rock bodies and wall rocks,and NW-trending cleavage belt developed in the wall rocks is the host structure of outer contact deposit.The author believed that enhancing the study on the ore bearing potential of rock bodies and NE-trending faults which penetrated through rock bodies were break-through of prospecting for inner contact deposits;outer contact deposits mainly required enhancing prospec-tion works in the area paralleled to cleavage belt,and known mining area should increase the control over shallow parts along the strike. |
