| 中文摘要: |
| 古马岭—门坎哨区处于浑江陷褶断束与鸭绿江断裂所夹持的三角地带内,金矿体产于近东西向的构造带内。矿体具有厚度大、品位低、产状稳定之特点。矿体为破碎带蚀变岩型,含矿岩石主要为夕线黑云斜长片麻岩,矿石矿物为黄铁矿,蚀变有硅化、绢云母化、绿泥石化、碳酸盐化等。矿体与化探、物探异常吻合性较好。该区具备找寻低品位大厚度金矿体的条件,深部应有较大的成矿空间。 |
| 英文摘要: |
| The gold deposit is located in the triangle region constrained by the Hunjiang depressed fold and fault bunch and the Yalu River fault, the gold ore bodies occur within the near EW-trending tectonic belt. The gold ore body has characteristics of large thickness, low grade, and stable extension. The host rock is mainly fibrolite biotite plagioclase gneiss, and the main ore minerals is pyrite, main alteration types include silicification, sericitization, carbonation and chloritization. The gold deposit type belongs to the structure-controlled altered type deposit. The spatial distribution of gold ore body has good consistence with the geochemical and geophysical anomalies. There is favorable geological conditions for discovering the low grade and large tonnage gold deposit in this region, and the gold mineralization is still open along the dipping direction. |
