| 摘 要： | 竹子沟金矿位于中秦岭礼县-柞水褶皱带西段,岷(县)礼(县)金及多金属成矿带内,矿体主要分布于F1断裂带西南侧的次级北西向断裂中.赋矿层位为中泥盆统何家店组,围岩蚀变主要有硅化、黄铁矿、绢云母化.区内地化异常元素组合为Au、As、Ag、Sb、Pb.通过综合研究初步总结了适合本区地质-地球化学找矿模型.通过与邻区对比、分析,认为该区找金潜力较大,并指出了温家沟等数处有进一步工作价值的找矿靶区.

| Abstract: | The Zhuzigou gold deposit is located in the western part of the Lixian-Zhashui folding belt and in the Minxian-Lixian gold-polymetallic mineralization zone of the middle Qinling Mountains. Gold orebodies are distributed in the secondary NW-striking faults at the SW side of the main fault F1. Gold mineralization occurred in the Middle Devonian Hejiadian Formation. Silicification, pyritization and sericitization are the main alteration in the wallrocks, with Au, As, Ag Sb and Pb geochemical anomalies. An exploration model based on the geology and geochemistry studies is proposed. By comparison and analysis with nearby district, it is concluded that there is a great gold exploration potential in the area. Exploration targets such as Wenjiagou have been recommended for further work. |
