摘　　要：平顶山金矿床的黄铁矿晶体形态研究表明，产于不同地质体的黄铁矿晶体表面微形貌有较大的差异，这种差异反映了黄铁矿结晶时的环境特点。不同时期形成的黄铁矿在晶体形态和粒度上是有差异的，并且含金性亦不同，晶形好粒度大的黄铁矿含金性差。With the research of the crystal shape of pyrite in the gold deposit of Pingding Mountain, the author found that the surface microtexture of pyrite orystal exist diversity in diflerent geological bodies. The diversity reflects the charateristics of the surroundings when pyrites crystallize. In the different mineralization stages, pyrites have different features about crystal shapes and grain gradsizeses. The crystal euhedron and coarse-grained pyrifes are charaeterized as gold-free, however, the non-orystal shape and fine-grained pyrites are gold-bearing.
