摘　　要：磁黄铁矿是辽宁五龙金矿含金石英脉矿体中主要金属矿物之一,它形成于早期硫化物结晶阶段,主要以六方晶系形式出现.不同特征的磁黄铁矿含金性不同,其中细粒的、深色的、硬度较小的、与多金属硫化物共生的磁黄铁矿含金量高.磁黄铁矿的标型特征可以作为寻找和评价金矿床的指示标志.pyrrhotite is one of the main metallic mineral in the orebody of the auriferous quartz vein of Wu-Long Gold Deposit, which occurred in early sulphide crystalline stage. Most pyrrhotites are present in the form of hexagonal system.The gold-bearing property of pyrrhotites in different characteristics are quite different, however, the gold content of fine-grained, dark-colored and less hard pyrrhotite and those pyrrhotites intergrown with other complex sulphide minerals are high. The typomorphic characteristics of pyrrhotite can be regarded as indicator of prospecting and evaluating for gold deposit.
