始于1994年的极地乌拉尔地区原生金矿点,(科日姆河盆地,巴尔巴尼尤河左支流河上游)的矿化研究表明,该矿化是发育在流纹岩中的新类型Au-Pd-TR热液矿化。矿点位于背斜南坡,产在呈岩礁式的流纹岩中。现已揭露出4条含矿的片理化带,带内见有大量石英-钠长石脉和铬云母细脉。在中间的2条带上有15个露头发现了明金。2个探槽样品分析的金品位为42×10~(-6)和84×10~(-6)。周围流纹岩蚀变的矿物组合为:钠长石-绢云母(+铬云母)-石英。矿石中则鉴定出下列矿物:石英、钠长石、铬云母、褐帘石、重晶石、锆石、独居
Mineralization studies of primary gold deposits in the Urals in the Polar Regions of the Polar Region (upstream of the Kozim Basin, the Upper Tributary of the Barbarnyou River) since 1994 indicate that this mineralization is a new type of Au -Pd-TR hydrothermal mineralization. Located on the southern slope of the anticline, the ore deposit is produced in rock-reef-type rhyolite. Has now revealed four ore-bearing strip with the band, see a large number of quartz-albite vein and chrome mica vein. There are 15 outcrops in the middle of the 2 found Ming Ming. The gold samples of the two trenches were 42 × 10 -6 and 84 × 10 -6. The rhyolite mineral assemblage around the rhyolite is albite-sericite (+ chrome mica) -quartz. The minerals are identified in the following minerals: quartz, albite, chrome mica, brown curtain stone, barite, zircon, solitary
