贵州赫章县青冈林铅锌矿地质特征及成因

Geological Features and Ore Genesis for the Qingganglin Pb-Zn Deposit in Hezhang, Guizhou

通过对赫章青冈林铅锌矿的成矿地质条件、矿体产出特征、铅锌矿石化学成分、矿床成因类型等的分析、总结,认为矿床与构造关系密切,属于后成层控矿床,初步认为该矿床矿质主要来自下古生界地层,主要受玄武岩浆喷发和燕山构造运动两阶段矿化作用成矿。

This paper believes that the Qingganglin Pb-Zn deposit in Hezhang, Guizhou is a subsequent stratabound one. Ore material was derived from the Lower Paleozoic. The Pb-Zn ore-formation was in close relationship with tectonism and might be divided into two stages such as basalt flow effusion stage and Yanshanian movement stage.
