吉林省白山市二岔铁矿位于中朝准地台、辽东台隆、铁岭-靖宇台拱、龙岗断块中南部边缘，太古宙早期区域内发生幅度较大的拗陷，接受广泛巨厚的一套粘土质、砂质碎屑岩类沉积，其间夹有硅铁质沉积并伴有火山（基性）岩浆喷溢活动，太古宙末期强烈造山运动使这些沉积岩层发生强烈挤压，形成褶皱构造及区域性断裂。伴随强烈造山运动致使太古宙地体发生中、深度区域变质作用与混合岩化作用。区域变质作用和混合岩化作用，对本区火山沉积变质铁矿的形成具有重要意义。二岔铁矿已探明基础储量（122b）30.26万吨、资源量(333)11.44万吨。

Jilin Baishan Ercha iron ore is located in Sino-Korean paraplatform, Liaodong anticlise, Tieling Jingyu platform arch, central south edge of Longgang block, the larger depression occurred early Archaean in the region widely ,it deposited a thick clay, sandy clastic, In which deposited silicon iron deposition and accompanied by the volcanic (basic) magma eruption, the strong orogeny made these sedimentary rocks strong extrusion, formed folds and regional fault at the end of the Archaean. The medium high degree regional metamorphism and hybridization occurred in Archaean terrain with strong orogeny. The regional metamorphism and hybridization had important signiifcance on the formation of the volcano-diagenetic metamorphism iron. They estimate basic reserve (122b) 302 600 tons and resource extent (333) 114 400 tons of Ercha iron ore.
