| 摘 要： | 辽宁省岫岩县五道沟铁矿产于古元古界辽河群里尔峪组变质岩中,层位控矿的特点明显;铁矿体的围岩为黑云斜长变粒岩,矿体与围岩界线清晰;矿体的围岩蚀变不甚强烈,晚期构造和闪长玢岩脉穿切铁矿体,但对铁矿体无明显的破坏。该矿床与区域上杨林式铁矿可以对比,矿床成因属于火山沉积-变质铁矿,成矿时代为古元古代。

| Abstract: | Wudaogou Fe deposit in Xiuyuan county of Liaoning province occurs in metamorphic rocks of Li''eryu formation of Palaeo-proterozoic Liaohe group and is obviously stratobound. Ore bodies contact sharply with the enclosing rock of biotite-hornblende granulite and without strong alteration. Late structure and dioritic dyke cut the ore bodies without destruction. The Fe deposit can be correlated with Yanglin style Fe deposit regionally and genetically it is a Palaeo-proterozoic volcanic sedimentary-metamorphic Fe deposit. |

| Keywords: | Wudaogou Fe deposit biotite-hornblende granulite magnetite-actinolite rock Li''eryu formation of Palaeo-proterozoic Liaohe group Liaoning province |
