河南省南召县银洞山铅锌矿床地质特征

Geological characteristics of the Yindongshan Pb-Zn deposit in Nanzhao County,Henan Province

银洞山铅锌矿区位于华北地台南缘以南的活动带,属阿森特—加里东地槽型陆缘海沉积变质相,区内岩浆活动频繁,构造广泛发育,是成矿的有利地带。通过对该区矿床地质特征的总结,指出本区金属矿床具有多成因叠加特点,属与一定的地层岩性组合有关的热液矿床,对指导该矿区下一步地质勘查及找矿,扩大资源具有积极的作用。

The Yindongshan Pb-Zn deposit is located at the active belt northwards to southern edge of North China Platform,which belong to Asente-Caledonian continental sources marine sedimentary metamorphic phase of geosyncline type.With active magmatic movements and broad development of structure,the studying area is a favorable area for mineralization.According to the conclusion of the geological characteristics of the deposit in this area,the study has pointed out that the metallic deposits in this mining area are...
