以前对亚美尼亚铜钼矿床的矿石中钯和铂的分布曾作过研究。很有意义的是在该矿石中发现有稀少的铂族元素——锇。锇在这里是由于长寿命同位素 Re~(187)放射性衰变而形成的:Re_(75)~(187)→Os_(75)~(187)+β粒子,半衰期为4.3×10~(10)年。因此可以设想,锇能在主要富铼的矿物——辉钼矿中富集。作者曾研究了赞格祖尔铜钼矿床中含铼 The distribution of palladium and platinum in the ore from the Armenian copper-molybdenum deposit was previously studied. It is significant that there is a rare platinum group element found in this ore - osmium. Osmium is formed here due to the radioactive decay of Re ~ (187), a long-lived isotope. Re 75- 187 → Os 75- 187 + β particles have a half-life of 4.3 × 10-10 years . It is therefore conceivable that osmium can be enriched in the major rhenium-rich mineral, molybdenite. The authors have studied rhenium in the Zanzur copper-molybdenum deposit
