摘要
孟营子矿区出露地层有侏罗系和二叠系,区内的燕山早期花岗斑岩体呈岩枝状产出,局部有Cu、Pb、Zn、Ag矿化显示;花岗斑岩体与围岩接触带部位绢云母化和硅化蚀变很发育,规模较大,是有利的成矿空间;经钻探初步揭露,在接触带上发现具有工业意义的岩浆期后热液脉型矿体。通过分析,认为孟营子矿区成矿地质条件优越,具有中-大型规模的银铅锌矿找矿潜力。
Jurassic and Permian stratum widely occur in Mengyingzi. It is found that there are locally Cu, Pb, Zn and Ag mineralization showings in the granite-porphyry bodies in Early Yanshan period.The contact belts between granite-porphyry bodies and wall rocks are developed for formation of ore deposits. And by preliminary drilling Sericitize and silicification, which can provide room test, Postmagmatic hydrothermal vein type ore deposits which have economical value mainly have been found. The result shows that the study area is potential for Ag, Pb, Sn deposit in middle to large scale. All these are indicate that this region has benign prospecting potential.
