辽北十八家子铅锌矿区位于中朝准地台胶辽台隆与内蒙地轴的接壤部位，地壳运动比较频繁，火成岩、变质岩广泛发育。铅锌矿体赋存于角岩中；角岩之主体属钙硅酸盐角岩型，呈扁豆状赋存于混合岩中；矿床成因类型属混合岩化中温热液角岩型多金属矿床。%Shibajiazi lead-zinc mining area of northern Liaoning province is located in the boundary of Jiaoliao platform uprise and Inner Mongolian axis of China and North Korea's paraplatform. The diastrophism there is frequent, and the igneous rocks and metamorphic rocks are widely developed. Lead-zinc ore body is in hornstone. The main part of hornstone is calcium silicate, and it is lenticular in the migmatite. The genetic type of ore deposit is polymetallic deposit with migmatization medium temperature hydrothermal hornfels.
