MINERAL COMPOSITION OF HEAVY CONCENTRATES OF THE KAMENNAYA SANARKA GOLD PLACER (SOUTH URALS)
The paper presents the results of study of heavy concentrates from the Kamennaya Sanarka gold placer in the South Urals. The +1 mm fraction contains kyanite, garnet and staurolite, which are characteristic of host shists, whereas the –0.5 mm fraction contains accessory minerals of granite plutons; t...

| description | The paper presents the results of study of heavy concentrates from the Kamennaya Sanarka gold placer in the South Urals. The +1 mm fraction contains kyanite, garnet and staurolite, which are characteristic of host shists, whereas the –0.5 mm fraction contains accessory minerals of granite plutons; the –1 + 0.5 mm fraction is transitional in composition. Native gold in heavy concentrates is rounded and angular. It mostly contains Ag and Cu (in single grains). Mercury in the composition of gold occurs as a result of previous gold amalgamation. On the basis of morphological and chemical features, native gold could probably be sourced from gold-(sulfide)-quartz veins in schists and gneisses, which compose the bedrock, as well as from quartz veins of the Kamennaya Sanarka granite pluton. |
