Abstract

The results of the study of the platinum group minerals of the Baimka gold placer cluster, Western Chukotka, Russia, are presented. Platinum group minerals belong to the iridium–platinum and platinum mineralogical-geochemical types with the Late Jurassic cumulative pyroxenite-gabbro complexes as a probable source. Platinum group minerals came to alluvial gold placers primarily from intermediate reservoirs, which is the Volgian volcanic-sedimentary sequence J₃v_2–3. Rounded silicate glass inclusions are a specific feature of platinum minerals from the Baimka placer cluster.

楚科奇西部拜姆卡金矿床群的铂族矿物：新数据

摘要介绍了对俄罗斯西楚科奇Baimka金块群中铂族矿物的研究结果。铂族矿物属于铱-铂和铂矿物地球化学类型，可能的来源是晚侏罗世累积辉长岩-辉长岩复合体。铂族矿物主要来自中间储层，即伏尔加火山沉积序列 J3v2-3。圆形硅酸盐玻璃包裹体是拜姆卡砂金矿群铂矿物的一个特殊特征。
