杨坪金矿床赋存于下古生界丹凤群大草坝组变火山—沉积建造中,金矿化严格受层间挤压破碎(片理化)带控制,赋矿岩性为蚀变的二云石英片岩、绢云母石英片岩、绿泥石英片岩等变质岩及黄铁矿化石英脉,金矿化受变质、构造及次生氧化三重作用控制.对杨坪金矿床的地质特征及控矿特征进行了系统的研究,总结了找矿标志,并指出了找矿方向.
Yangping gold deposit occurs in the Lower Paleozoic Danfeng Group Caoba Unit volcano -sedimentary structure.The mineralization is strictly controlled by interlayer compressive rupture zone and the host rocks are meta -morphic rocks like altered two-mica-quartz schist,sericite schist and chlorite quartz schist ,and pyritization quartz vein.Gold mineralization is controlled by three factors,namely alteration,structure and secondary oxidation .The paper systematically studied the geological characteristics and ore -controlling features of Yangping gold deposit ,summarized the prospecting indicators,and pointed out the prospecting direction .
