Аннотация: In the Yenisei province the gold and sulphidic formation can be subdivided into two types (subformation) objectively reflecting large classes veshchestvenno similar, but geologically polytypic fields: 1) the olimpiadinsky type is developed in carbonaceous and terrigenous and carbonate and terrigenous thicknesses in association fromПоказать полностьюbatolita of granitoids (olimpiadinsky type) and 2) the poputninsky type is localized in a volcanogenic and terrigenous substratum in association with belts of ultrabazit and bazit. The Poputninsky type of a gold and sulphidic formation is most fully studied in Razdolinsky ore knot where fields of this perspective типас by the large reconnoitered potential of ore gold (a field Poputninsky, Snake, Light, Antoninovsky) and considerable prospects of identification of new fields of this type are localized. The Poputninsky gold field is reference object for this type. The field is localized in the periklinalny short circuit of the Rybinsk anticline put (from the South to the north) by intrusive breeds of poputninsky (metapiroksenita) and Isakovsky (metabazita) of the complexes which are breaking through thickness of breeds of kordinsky suite lower. The subconcordant the ore-bearing mineralized zone (OBMZ) has the North - northeast-east direction, to it the saddle form is characteristic. It is localized in the field of contact the fillitovidnykh of slates and the spreading pack blocking packs talc - chlorite-carbonate the apoultrabazitovykh of slates. Rudovmeshchayushchy thickness is subjected to intensive tectonic study (a multi ordinal skladchatost, a rasslantsevaniye) with imposing of the intensive gidrotermalno-metasomatic processes shown in the form of an okvartsevaniye, a karbonatization, hloritization, an otalkovaniye, sulfidization which led to formation of ore bodies of a field of a gold and sulphidic formation. The ore-bearing mineralized zone has an appearance of a horseshoe krutopadayushchy deposit with bends, an overclamping, razduva and splittings, with power from 20-30 m to 100-200 m and more. The zone is complicated by two cross pectineal blind ledges of metaultrabazit with a vertical amplitude of 200-600 m which metasomatitam clothe from all directions and with the accruing steepness plunge into the North - the North western direction. All known ore bodies of a field are concluded in this mineralized zone, and intensity of an orudeneniye has direct positive correlation with the level of manifestation of the imposed gidrotermalno-metasomatic processes (a berezita, a listvenita) which most significant indicators, are a carbonate - quartz vein прожилковые and the sulphidic prozhilkovo-interspersed mineralization zones. The main ore-bearing metasomatita are quartz-fuksit-carbonate (listvenita) and carbonate carbo-naceous quartz-seritsitovye of education (berezita). Geochemical specialization of an ore field of the Poputninsky field is reflected by secondary and primary auras of dispersion of gold, arsenic and antimony, complex auras of nickel, cobalt, chrome, copper. By results of works within poorly studied territory of Razdolinsky ore knot sites, perspective on a gold orudeneniye are revealed: 1) Miner, 2) Light, 3) Snake Western, 4) Sorochinsky, 5) Guselnikovsky, 6) Antoninovsky, 7) Poputninsky, 8) Moiseevsky, 9) Bogolyubovsky Severny. The expected potential of expected resources of ore gold of these sites is estimated about 200 t.
