摘要
松山—石山断隆位于山海关—北镇隆起带中部,具有花岗岩—绿岩的构造体制,即在低变质区中分布有金矿床。该断隆上的金矿床产于太古界建平群老变质杂岩系中,金矿床严格受断裂构造控制,矿化类型为含金石英脉型,矿体规模小,埋藏浅、品位高。
Songshan-shishan anteclise located in the middle parts of the Shanhaiguan-beizhen umbones was characterized by the granite-greenstone structure system i.e. the low-grade metamorphic zones have hosted the gold ore deposits occurring in the old metamorphic complex rocks in the Archean Erathem Jianping group,and the gold-bearing quartz veins type ore deposits strictly controlled by the fractures have specific characteristic of the shallow-buried and smallscale but high-grade orebodies.
