| 摘 要： | 老湾沟金矿位于秦岭褶皱系礼县-柞水海西褶皱带东段西部，处于唐藏-丹凤-商南大断裂带和礼县-凤镇-山阳大断裂带之间，属凤太多金属成矿带。通过对区域地质特征和老湾沟地区金矿的地层、构造、岩性及围岩蚀变等矿床地质特征研究分析，结合以往在该地区的工作成果及认识，认为该地区矿体受断裂破碎带控制，金矿化在构造带中以浸染状分布于硫化物石英细脉、网脉中，是构造蚀变岩型金矿。在总结矿床地质特征的基础上，进一步对老湾沟金矿进行了控矿因素分析。

| Abstract: | Laowanggou gold deposit is located in the west of east Hercynian Lixian-Zhashui fold belt, which belongs to Qinling fold system between Tangzang-Danfeng-Shangnan fault and Lixian-Fengzhen-Shanyang fault. According to the analysis on regional geological features and ore deposit geological characteristics of Laowangou, such as the strata, tectonic, lithology, and wall rock alteration and so on, the orebody should be controlled by the fault fracture, the gold mineralization disseminated in sulfide quartz veinlet and nets of arteries of tectonic belt. It is the tectonic altered rock type gold deposit. |
