摘要
瑶岭钨矿由北矿区、东矿区和白基寨矿区3个矿区组成,其中北矿区是主要生产矿区,以石英脉型黑钨矿为主。在对北矿区大比例尺填图过程中,我们发现矿区地表地层单一,主要为寒武纪沉积的变质砂岩和板岩。针对这种情况,我们采用土壤地球化学测量、物探磁法测量、钻探等工程方法对寒武纪地层进行研究,综合分析了矿区地质特征、地球物理磁法特征及地球化学特征在对矿脉水平分布、矿脉垂直分布、蚀变矿物因素、构造因素、热接触因素和成矿因素的外在表现,从而建立起矿区寒武纪地层对矿化的指示体系表,并指出瑶岭钨矿北区深部和东南部有很大的找矿潜力,是值得继续找矿的有利目标地段。
The Yaoling tungsten deposit is composed of noah block, east block and Baijizhai block. The noah block is the main production mine and mineralization type is mainly quartz vein wolframite. Large - scale geological mapping covering the north block was undertaken and it is found that the strata on the surface is simple, metamorphosed sandstone and slate of Cambrian age. Soil geochemical sampling, ground magnetic survey and drilling were carried out to study the Cambrian strata. The horizontal and vertieal distribution of veins, alteration, struetnral controls and contact metamorphism were investigated, and mineralization identifying feature table in Cambrian strata in north YaoLing was set up. It is predicted that the deep and the southeast part in north block is highly prospective for searching for the new mineralization.
