摘要
九龙庙金矿位于钦杭成矿带南段,成矿物质来源于冷家溪群小木坪组(Pt2x)岩层中,矿脉发育严格受断裂带的产状、形态制约。硅化、黄铁矿化及毒砂化与成矿关系密切,也是直接的找矿标志。尤以充填交代作用形成的石英脉发育地段金品位特富。综合该矿区域地质、矿床地质特征,可知岩性和构造是该区主要的控矿因素,多期次热液蚀变是成矿的关键。该矿为沉积变质再造中低温热液型金矿床。
Jiulongmiao gold deposit is located in the southern section of Qin-hang metallogenic belt, the ore-forming material comes from the Lengjiaxi xiaomuping group （Phx）. Vein strictly controlled by fault occurrence, form. Silicide, pyrite and arsenopyrite closely related to mineralization, and direct ore-prospecting criteria. Especially in the filling metasomatism form of quartz vein gold grade development location rich. Integrated geology, ore deposit geological characteristics of the mine area, lithology and structure is the main ore-controlling factors. Multiple stage hydrothermal alteration is the key to the mineralization. The mine for sedimentary metamorphic fluid （medium to low temperature type gold deposit.
