| 摘 要： | 在岩浆及高温热液中，拍族元素以纳米液态铂族元素单质、铂族元素与其它金属元素的纳米液态合金、纳米液态铂族元素的硫、砷化物迁移。在中、低温热液及表生条件下，除呈上述固态纳米铂族矿物随流体迁移外，还呈配合物形式迁移。然后它们在合适的条件下沉淀富集形成矿床。此外，还讨论了铂族元素与金地球化学条件的异同。

| Abstract: | PGE migrate as nm-sized particles of simple substance,intermetallic compounds,sulfides and arsenides in magmatic and high-temperature hydrothermal solution and,in addition,as complex in meso and hypothermal solution and localize to form ore deposits of PGE under favourable conditions. Similarity and difference between PGE and gold in geochemistry are discussed. |
