| 摘 要： | 东矿带东部段是老柞山金矿区内最大的金矿床。矿体受NW向断裂破碎带控制，压性及压扭性脆一韧性脆性断裂控制金矿体。矿体赋存在构造角砾岩和矽卡岩内，呈平行脉状、似层状、透镜状陡倾斜平行排列，延深大于延长。矿石类型以浸染状为主，金与毒砂、磁黄铁矿密切共生。成矿深度超过11km，属典型中深成造山型金矿，除去成矿后期剥蚀等因素，深部应有很大的找矿潜力。目前激电测深深度在300m以内，钻探深度达500／11，主矿体呈尖灭再现，控矿断裂带、矽卡岩带仍有下延的趋势，深部可能出现第二成矿空间。

| Abstract: | The eastern section of the east ore belt is the largest gold deposit in Laozuoshan gold deposit region. The ore body is controlled by the NW-trending fractured faults belt. The gold ore body is controlled by the compression and compression-torsion shear brittle and brittle-ductile fault. The ore body exists in tectonic breccia and skarn. It arranges as steep tilt parallel vein, layer and lens shaped. The extension is greater than the extension. The types of orebodies are mainly disseminated. Gold ore bodies exist closely together with arsenopyrite and pyrrhotite. The depth of the ore body is more than 11 km. It is a typical middle or deep orogenic gold deposit. There should be a lot of deep exploration potential without considering the late-forming factors such as erosion. At p resent, the depth of IP sounding is less than 300 m, and drilling depth reaches 500 m. The main ore body doesn’t appear continuously. The ore body controlling faults and skarn zone still tend to descend. The lower part may be the second orebody forming space. |
