槽子沟铜铅锌矿床是一个小而富的多金属矿床,锌储量大于铅大于铜,尚伴生有银.该矿床在地质特征、控制因素和形成条件上都别具一格,是我国少见的一种多金属矿床类型. 区域地质概况矿床位于川北龙门山断褶带北段次级构造——李家沟背斜南端倾伏部分.龙门山断褶带,北以汉江深断裂为界,与昆仑-秦岭地槽南加里东褶皱带之基底——元古界碧口群海相变质火山岩系毗邻.李家沟背斜为一轴向北北东-南南西的短轴背斜,元古界刘家坪组构成核部,两翼及倾伏端依次为震旦系及下古生界地层(图1).
The Zouzigou copper-zinc-lead deposit is a small and rich polymetallic deposit with a zinc reserve greater than that of lead and greater than that of copper, and is associated with silver. The deposit is distinctive in geological features, controlling factors and formation conditions and is rare in our country Metallic deposit type Regional geological overview The deposit is located in the northern part of the northern Longmen Shan fault fold belt in northern Sichuan - the southern part of the Lijiagou anticline. The Longmen Shan fault fold belt is bordered by the deep Hanjiang fault in the north and connects with the Kunlun-Qinling Mountains The basement-Proterozoic Bikou Group marine metamorphic volcanic rocks are adjacent to the basement of the southern Caledonian fold belt in the Trough.Lijiagou anticline is an axially north-east-south-south-west short axis anticline, and the Proterozoic Liujiaping Formation The core, wings and dip are followed by Sinian and Lower Paleozoic strata (Figure 1).
