| 摘 要： | 太白金矿的矿化共经历了４个成矿阶段，其中黄铁矿－含铁白云石阶段是最的金矿化阶段。黄铁矿为主要载金矿物。黄铁矿中铂的含量与Ａｕ＋Ａｇ含量呈负相关，金矿物主要以微米级的自然金产于Ⅱ，Ⅳ阶段的黄铁矿中，成色８７９－９６５，金的成色总体上向深部呈升高的趋势。自然金中铂含量与金的成色呈负相关。黄铁矿中有高的Ｐｔ含量和Ｔｅ含量。黄铁矿具有混合导型特点，δ＾３４Ｓ值为６．５×１０＾－３－１１．６×１０＾－３。

| Abstract: | According to electron probe analysis of 12 sampIes, As, Se, Ni, Au, Pt were detected as trace element in pyrite. Pt content is negahve correlated with Au+Ag content The native gold is closely associated with pyrite from stage 2 and stage 4. It occurs is the, fissure filling or on the crystal boundary of pyrite.The finess of gold is falling from 1290 level to 1350 level, which indicated that the ore-forming temperature is from high (downside) to low (upside). Pt content is negahve cormlated with the finess of gold. High Pt and Te content indicated that the ore forming of this deposit is related with abyssal magmatism. Pt content of pyrite is not only genesis significance but also of significance of explorahon. |
