Abstract

For the first time, the authors present data on the gold content of metasomatite from the Enganepe Ridge, the Polar Urals. Pyrite-sericite-quartz, pyrite-sericite and sericite metasomatites occur after rhyolite and basalt. The relationship between gold grade and post-magmatic processes of near-fissure low-temperature metasomatism is shown. Native gold in the metasomatite is moderately fine (800–900 ‰); typomorphic impurities are represented by silver and mercury. Similar gold was previously found in placers. Potential of the area for native gold and possible genetic type of gold deposits is discussed.
