中文摘要:
      陇孔沟金矿床位于北祁连托莱山成矿带上,是近年来在北祁连多金属成矿带上发现的规模最大的小型矿床。经1∶5 万水系沉积物测量和多种找矿方法手段,矿区内划分出3个矿群(Au1-3),圈出金矿体36条,其三矿群(Au3)为区内的主要矿带,带长1.1km,宽20~50 m,带内共有22条金矿体,长60~287 m,厚0.8~6.2 m,品位0.82~73.6g/t,且在地下2个120 m的中段深部控制,发现两条工业矿体和两条盲矿体。金矿体主要赋存于下奥陶统阴沟群上岩组火山碎屑岩段中,主要以脉状、板状、透镜状产出,受断裂破碎带控制,属构造蚀变岩型金矿。
英文摘要:
      The Longkonggou gold deposit is located in the Tuolaishan metallogenic belt of the northern qilian mountains,which is the largest small gold deposit in this metallogenic belt at present. After 1/50000 Stream Sediment survey and Through a variety of prospecting methods we have circled 36 gold orebodies and divided into three group (Au1-3), the third ore group (Au3) as the main metallogenic belt in the area, with a length of 1.1 km, 20 to 50m wide, and a total of 22 gold orebodies, 60-28m long, 0.8-6.2 m thick, 0.82-73.6 g/t value. Two industrial ore bodies and two blind ore bodies were found in two 120m underground interrupted deep control.The gold ore bodies occur mainly in the cataclastic andesite of the upper pyroclastic member of the Lower Ordovician Yingou Group, and are mainly produced in the form of veins, plates and lenses, controlled by the fracture zone.
