摘要
碧口群黄铁矿型铜金矿床产于前震旦纪古蛇绿岩套中.矿体受一定层位控制,分段集中,成群分布;赋存于基性火山岩及其凝灰岩向沉积碎屑岩过渡的部位,与透镜状含碧玉的磁(赤)铁矿石英岩密切相关,与围岩整合.矿体倾向延深大于走向长度.矿石以铜金为主,含一定量的钴、银和微量锌.
The pyrite type Cu-Au-deposit is located in the ophiolite suite of the Precambrian Bikou Group.Ore bodies, being controlled by a stratigraphic horizon, concentrated in segmentation and distributedin crowds, occur in a position of transition from basic volcanic rocks and their tuff towards the sedimentary clastic rocks. They are closely related with the lenticular jasper-bearing magnetite (hematite)quartzlte and lie in comformity with host rocks, with their depth extents along the dip larger thantheir strikewise lengths respectively. The ores chiefly contain copper and gold as well as cobalt andsilver (in small quantities), also associated with a trace amount of zinc.
