CHARACTERISTICS OF PRIMARY GEOCHEMICAL ZONINGIN COPPER-IRON-GOLD POLYMETALLIC DEPOSITS OFSOUTHEASTERN HUBEI AREA AND ORE-PROSPECTINGSIGNIFICANCE OF THE ZONALITY PATTERN
Based on the researches conducted by previous workers, this paper has tentativelysummarized and generalized characteristics of primary geochemical zoning in copper-iron-goldpolymetallic deposits of southeastern Hubei area and established ltthe assemblages of major oredeposit types in this area and an integrated pattern of geochemical zoning. A discussion is givenon the practical significance of ole-.uout zoning of single-layer and multilayer orebodiea withintypical ore deposits of the area and the axial zoaality pattern in the prognosis of deep blindorebodiea. The indication significance of characteristic indicator elements in the ore deposits ispointed out, and the criteria for finding blind deposits are presented.
