Gold mineralization prospects of lower Ordovician gabbroids of lekvojsky complex (Niyayu-Niyakhoy gold-bearing region, the Polar Urals)

Gold-bearing features of sulfide mineralization in Enganepe-Manitanyrd region are supposed to be related with shearing zones and Ordovician magmatic intrusions. The paper gives characteristics of ore mineralization from endocontact zone of gabbro-dolerites referring to Upper Ordovician Lekvojsky complex within one of potentially perspective areas of Manitanyrd ore region. Morphological and geochemical features, studied with SEM Tescan Vega-3 EMF X-Max in polished sections, allow detailing magmatic, hydrothermal (high-temperature and relatively low-temperature) and metamorphic ore associations, and also determining their formation conditions. Ore mineralization doesn’t exhibit gold-bearing features.
