Zhaopingfang mining area is located in eastern part of Liaohe smooth plain, which belongs to marine –deposition plain. The deposit occurs in under the Quaternary sola, formed in hornblende magnetite quartzite of Cigou Formation, Anshan Group of the Archaeozoic erathem, which belongs to Anshan type iron deposit. The paper introduced in detail geological features of the ore deposit, genesis. The protolith shows marine tholeiite-fersilicite sedimentary structure, which belongs to volcanic sedimentary-metamorphic reformation deposit. Meanwhile, the paper proposed ore-prospecting criteria for further ore-prospecting in the study area.
