与冬瓜山铜(金)矿床成矿关系密切的岩体为青山脚岩体,主要由石英二长闪长岩组成。该岩体主要分布于冬瓜山铜(金)矿床34线~54线东南部,主要受北东向构造控制,岩体长轴方向与地表构造方向一致。岩体呈上窄下宽的岩墙状产出,地表出露宽度仅为50~100 m,至-400 m标高宽约150 m,-600 m标高宽度可达300 m以上。岩体总体呈北东走向,倾向南东,倾角大于75°。岩体两侧小岩枝发育,呈“枝
The rock mass closely related to the mineralization of the Dongguashan copper (gold) deposit is the Qingshan footed rock mass, which is mainly composed of quartz diorite. The rock mass is mainly distributed in the southeast of line 34 to line 54 of the Dongguashan copper-gold deposit, and is mainly controlled by the NE structure. The direction of the long axis of the rock mass is consistent with the surface structure. The rock mass is in the shape of rock wall with narrow width and width. The width of the surface exposed is only 50-100 m, the height and width of -400 m is about 150 m, and the elevation width of -600 m is more than 300 m. The rock mass is generally north-eastward with a tendency of more than 75 ° to the east. Small rock on both sides of rock development, was ”sticks
