摘要
李家沟金矿床位于"勉略宁三角地区"东南部鸡公石向斜南翼,矿体产于下震旦统雪花太坪组硅化白云岩中,在圈出的四十几个金矿(化)体中主要有细脉浸染碳酸盐岩型金矿体和石英脉型金矿体,其分别受北东东向断裂F2和X型的北东、北西向断裂控制。
Lijiagou gold deposits is located in the Mianxian-Lueyang-Yangpingguan copper , gold polymetallic mineralization clusters of the Jigongshi syncline south wing .Ore bodies are found in Lower Sinian system Xuehuataiping group silicide dol-omite.In forty several gold circle have disseminated veinlets carbonate rock type gold deposit and quartz vein type gold ore . Its are respectively controlled by the NEE trending faults F 2 and X NE, NW faults ,It belongs to sedimentary metamorphic complex hydrothermal type gold deposit .The formation of ore deposits mainly integrated control by stratigraphic lithology , structure, magmatic rocks.
