| Abstract: | This paper analysed geochemical habit of the gold in superficial oxidation zone,concretely studied conditions of oxidation leaching and enrichment and preservation of the gold in superficial oxidized zone of the typecal super micrograined impregnationtype gold deposits, which consist of: the characters of the orebody and ores, climate condition, elevation and denudation depth and emergence circumstances of the orebody, conditions of landform and geo-morphology and hydrogeology, develoment degree of the oxidation zone and type of oxidation shell, change factors on the shape and occurrence and thickness and gold tenor of the orebod-ies, and preservation of it. And 10 favourable conditions forming oxidition ores were summedup. Lastly, on the basis of these, it probed into prospecting for the oxidition ores of the gold deposits in this region. |
