Searching criterions and indications of gold mineralization in potash alkaline massifs (on example deposits and displays ore Aldanskiy Shield)
The deposits and displays ore of gold in the Mezozoic potash alkaline massifs Aldanskiy shield was the research objects. There are Rybinovoe and Novoe gold deposit in the Rybinovskiy alkaline complex and displays of gold in the Yakokutskiy, Yllymakhskiy, Tommotskiy and Mrachniy alkaline massifs. It...

| description | The deposits and displays ore of gold in the Mezozoic potash alkaline massifs Aldanskiy shield was the research objects. There are Rybinovoe and Novoe gold deposit in the Rybinovskiy alkaline complex and displays of gold in the Yakokutskiy, Yllymakhskiy, Tommotskiy and Mrachniy alkaline massifs. It was developed a complex searching criterions (magmatic, structure and geomorphological), straight and indirect indications of streaky-dessiminated gold mineralization in potash alkaline massifs. As magmatic criterion display the close spatio-temporal connection gold mineralization in the sericite-microcline metasomatites in the stocks potash alkaline syenites. Structure criterion manifested in separation in limits potash alkaline complex the structure elements, which controlled gold mineralization in hydrothermal altered syenites. Geomorphological criterion intended for evaluation the level erosion cut of ores stockworks in the alkaline massifs by correlation areas of spread alkaline syenites and rocks of volcanic roof. The straight searching indications of gold mineralization in the potash alkaline massifs include indigenous outcrops and mechanical aureoles of dispersion ore-bearing sericite-microcline metasomatites, heavy mineral aureoles of gold in eluvial-talus deposits above ores stockworks, alluvial gold placer. The indirect criterions are near-ores sericite-microcline metasomatites, primary and second geochemical aureoles of gold, silver, copper, molibdenium, lead and zinc, as well as magnetic, gravitational and electric anomalys in the geophysical fields. For implementation searching works on this type mineralization are offered complex searching methods, which include searching route, lito-geochemical and heavy mineral search, geophysical, minig and boring works. The same complex of searching criterions and indications gold mineralization in sericite-microcline metasomatites of alkaline massifs, suggested for use for implementation searching works in other provinces potash alkaline rocks (Western Aldan, North Baikal, Ural, North Kazakhstan, Central Kazakhstan, Armenian), perspective on this type gold mineralization. The use suggested predication works allowed are divided potentially ore-bearing areas in potash alkaline massifs on degree their prospective and single out immediate sections for implementation searching works on the gold. |
