摘　　要：通过对矿石光片进行系统的鉴定和研究,可确认此矿床为铁铜矿床,主要矿物为磁铁矿及黄铜矿。按矿石的成分、结构、构造特征划分出了矿物的生成顺序,进而区分出三个成矿阶段:即夕卡岩期、石英-硫化物期和表生期。According to the systematical study and identification of polished section of ore, we have deter- mined that it is a Fe-Cu deposit. The main minerals are magnetite and chalcopyrite. The mineral formation se- quence has been determined by the composition, texture and structure characteristics of ore and divided into 3 met- alloeenesis periods, ie. skarn. Quartz-sulfide and epigenetic period.
