西藏玉龙铜钼矿床地质特征分析
|
摘要
西藏玉龙铜钼矿床是青藏高原特提斯—喜马拉雅成矿带的一个超大型铜钼矿床,是我国新生代最典型的富碱斑岩铜矿。文章对玉龙超大型铜钼矿床地质特征进行了分析,认为玉龙铜钼矿床主要受构造控制,岩体内部次级褶皱、裂隙发育为热液运移、沉淀提供了有利空间;强蚀变角砾岩和碎裂带、片理化带往往是近矿或含矿层,为赋矿岩体的有利部位。
The deposit of copper and molybdenum of Yulong are the deposit of metallogenic belt of tethys-Himalayawith copper and molybdenum which is a porphyry copper mine of Cenozoic alkali in China. The article analyzed that characteristics of the deposit of copper and molybdenum, and found that the deposit of copper and molybdenum is mainly manipulated by tectonic, internal subprime drape, and fracture of rock mass with hydrothermal migration and precipitation for space. Also breccia, cataclastic, schistose zones were altered to be favor of ore-bearing intrusive body.
