1成矿地质背景黑龙江省牡丹江石英脉型岩金矿床位于佳木斯隆起西南部八面通隆起西端、牡丹江深断裂东侧,张广才岭幔坳区牡丹江隆起带的北东端(王文明,2005)。区域内出露的地层有中生界下白垩统穆棱组、猴石沟组、新生界第三系古新统虎林组,第四系全新统河床、漫滩、阶地堆积层。区域内的构造形迹以断裂构造为主,其中断裂构造主要为北东向构造,南北向构造次之,东
1 METALLOGENIC GEOLOGICAL BACKGROUND The Mudanjiang quartz vein type gold deposit in Heilongjiang Province is located at the western end of the Bamei uplift in the southwest of Jiamusi uplift, east of the deep Mudanjiang fault in the south of Jiamusi uplift, and at the north east end of the Mudanjiang uplift in the Zhangguangcai ridge-mantle depression area (Wang, 2005). The strata exposed in the area are Mesozoic Lower Cretaceous Muling Formation, Houshigou Formation, Cenozoic Eocene Holocene Hulin Group, Quaternary Holocene fluvial beds, floodplains and terrace layers. The structural features in the area are mainly fault structures, with the faults mainly consisting of the NE structure, the NE structure to the north and the east
