西秦岭庙沟金矿地质特征及找矿模型

西秦岭庙沟金矿床位于庞家河金矿床东部,属于秦岭—大别成矿省西秦岭Pb-Zn-Cu-Au成矿带。通过1∶10 000地质填图、1∶2000实测地质剖面,并利用探矿工程资料,详细查明各类地质体特征,建立地层层序,分析研究各类地质体的含矿性;详细查明各类构造特征,分析构造序次,研究各类构造与成矿的关系;查明地层、构造与矿体展布的关系,分析研究各类找矿信息,总结找矿标志和矿化富集规律,建立成矿模式和找矿模型,为地质找矿、矿体圈连和探矿工程布置提供基础地质资料。

Geological characteristics and exploration model of Miaogou gold deposit in Fengxian County,Western Qinling

The Miaogou gold deposit in the West Qinling Mountains is located in the eastern part of the Pangjiahe gold deposit and belongs to the Pb-Zn-Cu-Au metallogenic belt in the western Qinling, Qinling-Dabie metallogenic province. Through 1:10000 geological mapping, 1:2000 geological sections, and exploration data, the geological characteristics of various geological bodies are identified in detail, the stratigraphic sequence is established, and the ore-bearing of various geological bodies isstudiedanalytically. It is surveyeddetailedlyintectonic features, structural order and the relationship between various types of tectonics and mineralization., the relationship among strata, structure and ore bodies distribution. This assay studied analytically various exploration information and summarized prospecting signs and enrichment laws of mineralization, and established metallogenic model and exploration model. This assay provided basic geological information for geological prospecting, orebody encirclement and exploration work arrangement.
