庙沟金矿床位于柞水县大西沟―银洞子多金属成矿带上。矿带内发现两处大型(大西沟菱铁矿、银洞子银铅矿)、多处中小型(韭菜沟金矿、穆家庄铜矿、黑沟菱铁矿等)热(卤)水喷流沉积型矿床。矿区成矿条件优越，含矿地层为泥盆系大西沟组 D2 d 1-23上段的中部层位，含矿岩性为蚀变铁白云石石英脉、方解石石英脉，矿体在空间上受控于沿层间发育的 NW—SE 走向的铁白云石石英脉以及一些小规模的层间挤压构造破碎带，蚀变类型为铁白云石化、硅化、绢云母化、黄铁矿化等。本文总结其成矿地质特征，找矿标志，探讨了矿床成因，结合物化探成果及与热液成因矿床类比，认为本矿区深部具有良好的找矿前景。

Miaogou Au deposit was located in the Daxigou-Yindongzi polymetallic metallogenic belt of Zhashui county.Two large-scale (Daxigou siderite deposit,Yindongzi Ag-Pb deposit),and several small-scale (Jiu caigou Au deposit,Mujiazhuang Cu deposit,Heigou siderite deposit and so on)hydrothermal sedimentary exhalative deposits were also found inside the metallogenic belt.The metallogenic conditions of this mining area were favorable:the ore-bearing strata was the middle horizon of upper D2 d 1-23 of Devonian Daxigou For-mation,and ore-bearing rocks were altered ankerite quartz veins and calcite quartz veins,and in spatial terms orebodies were controlled by NW-SE trending interbeddedly developed ankerite quartz veins and several small-scale interbedded compression structural fracture belts,and the alteration types included ankeritiza-tion,silicification,sericitization,pyritization and so on.This paper summarized metallogenic characteristics and clues for prospecting and discussed on genesis of the deposit.Based on results of geophysical and geo-chemical prospecting and comparison with hydrothermal deposits,the author believed that the deep part of this mining area had a favorable prospecting potential.
