摘要
勉县白云寺铅锌矿床位于秦岭复合造山带勉略古岛弧隆起带之勉略蛇绿构造混杂岩带东段,由2条铅锌矿体组成,矿体呈规则脉状赋存于层内韧脆性断裂中,含矿地层为泥盆—石炭系金家河岩组。矿床类型为变质热液型。
Tectonically, the Baiyunsi lead-zinc deposit is situated in the east part of the Mianlue structurally ophiolitic melange zone of the Mianlue old island-arc upheave zone within the Qinling combined orogenic belt. The deposit is composed of two lead-zinc orebodies, hosted in the ductile-brittle fault at vein-type. The host of mineralization is in the Jinjiahe Formation of the Devonian-Carboniferous system. The type of the deposit is attributed to hydrothermal metamorphism.
