摘要
宝兴沟地区位于额尔古纳地块,北部位于漠河前陆盆地,南部位于塔河—翠岗岩浆弧。中生代以来经历了燕山期-喜山期滨太平洋大陆边缘活动和陆内块断升降演化大阶段,古亚洲洋陆缘增生演化大阶段。火山岩内发现1条铅矿体、1条金矿化体、4条铅锌矿化体。火山岩浆为成矿提供了物质来源和热源。
Baoxinggou area is located in the land of ergona, in the north of the mohe foreland basin, and the south is located in the tower river-cuioka magmatic arc. The Mesozoic era has experienced the evolution of the continental margin of the yanshan period and the continental margin of the Pacific Ocean, and the great stage of the evolution of the continental shelf. A lead ore body, 1 gold mineralization and 4 lead zinc mineralization were found in volcanic rocks. Volcanic magma provides a source of material and heat source for the mineralization.
