| 摘 要： | 采用电子探针分析（ＥＰＭＡ），对缅甸铂族金属砂矿中的矿物种类进行了研究。物质组成研究查明：主要组合矿物是Ｐｔ、Ｉｒ、Ｏｓ、Ｒｕ的自然元素和金属互化物。主要矿物是自然铂矿、铁铂合金、钌铱锇矿、等轴锇铱矿和铱锇矿。次要及稀有矿物是铂族金属的硫化物、砷化物、包括（Ｒｈ、Ｐｄ、Ｐｔ）２Ａｓ和（Ｒｈ、Ｐｄ、Ｐｔ、Ｎｉ）２Ａｓ两种陌生矿物、锑化物，以及含铂族元素的Ｆｅ、Ｎｉ、Ｃｕ硫化物。

| Abstract: | A mineralogical investigation of platinum-group metal placers from Burma was made by electron probe microanalysis (EPMA). The chemical composition has shown that the main composite minerals are native elements and intermetallic alloys of Pt, Ir, Os and Ru. The major minerals are native platinum, platinum-iron alloy, rutheniridosmine, osmiridium and iridosmine. The trace element Rh exists mainly in native platinum, platinum-iron alloy and Pt-containing osmiridium. The subordinate composite minerals are sulphides, arsenides, including the two unfamiliar minerals (Rh, Pd, Pt), As and (Rh, Pd, Pt, Ni), As, antimonides and sulphides of Fe, Ni, Cu , which contain platinum-group elements. |
