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。
Laowanggou gold deposit is located in the western part of the eastern section of the Xikian-Zhashui Hercynian fold belt in the fold belt of Qinling, between the Tangzang-Danfeng-Shangnan Great Fault Zone and the Liuxian-Fengzhen-Sanyang Great Fault Zone. Too many metallogenic belt. Based on the study of the regional geological characteristics and the geological characteristics of the gold deposits in Laowangou area, such as the strata, structure, lithology and wall rock alteration, combined with the past work and understanding in the area, it is considered that the ore body in this area is fractured and broken Belt control, gold mineralization disseminated in the tectonic belt in sulfide quartz veins, reticulate veins, is the structure of altered rock type gold. On the basis of summarizing the geological characteristics of the deposit, the ore-controlling factors of Laowanggou gold deposit are further analyzed.
