摘要
建阳井后钼矿位于闽西北隆起带东缘,浦城—永泰南北向构造岩浆活动带中部。矿床形成于燕山晚期,主要受区域上南北向断裂构造带控制的隐伏斑岩体控制。矿体以线脉-细脉及石英大脉型为主,围岩为中-晚元古代马面山群大岭组变质岩与加里东期二长花岗岩。
The Jinghou molybdenum deposit in Jianyang City is situated at the east fringe of Northwestern Fujian mole track, in the middle of the Pucheng-Yongtai north-south-trend fault zone. It was formed in late Yenshanian, and controlled by blind porphyry body, Which was controlled by Pucheng-Yongtai north-south-trend fault zone. There are three typical types of ore： line-vein Type, veinlet type, quartz vein type. ; quartz vein type and structurally altered rock type. The wall-rock lithology was metamorphic of the Daling Formation of Mamianshan Group in Mid-Proterozoic and adamellite in Caledonian epoch.
