鄂东南地区铜铁金等多金属矿床原生地球化学分带特征及分带模式的找矿意义

本文在前人研究的成果基础之上,初步总结和归纳了鄂东南地区铜铁金等多金属矿床原生地球化学分带特征,同时建立了本区主要矿床类型组合及地球化学分带综合模式,讨论了区内典型矿床单、多层矿体元素分带特征及轴向分带模式在进行深部盲矿预测中的实际意义;提出了矿床中特征指示元素的指示意义及寻找盲矿的标志。

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.
