| 摘 要： | 以黔西峨嵋玄武岩和辉长岩为测试对象，在矿物鉴定基础上，建立了Pt、Pd在硫化物、金属互化物、吸附态和硅酸盐类质同象不同赋存状态查定的流程，查明了峨嵋玄武岩中Pt、Pd是以硫化物态和金属互化物态为主，少量呈吸附态和硅酸盐类质同象态存在，讨论了峨嵋玄武岩铂钯状态丰度与铂族元素可能成矿的关系。

| Abstract: | The occurrence states of platinum and palladium in Emei basalt and gabbro are described in this paper. Based on the information from mineral identification, a new procedure for analysis of the phases and occurrence states of platinum and palladium as sulfide state, PGE alloy state, adsorbed state and silicate isomorphism state in geological samples has been established. The results show that the sulfide state and PGE alloy state are the major states of platinum and palladium in the occurrence and adsorbed state and silicate isomorphism state also existed in Emei basalt. On the basis of these facts, the relationship between the abundance of Pt and Pd states and the mineralization of platinum and palladium was discussed. |
