摘要
本文在总结驾鹿金矿田有关石英脉主要金属矿物地质产状、物性特征的基础上 ,系统对比性研究了蚀变岩和石英脉两类金矿床中产状、粒级、晶形、破碎程度不同的各世代黄铁矿中微量元素的含量、组合、比值特征及演化和不同世代的方铅矿、地表褐铁矿、软锰矿的含金性。建立了两类金矿的找矿矿物学标志。
On the basis of summarizing the occurrence and features of physical properties about quartz veins and main ore minerals concerned by predecessors in Jialu gold orefield,characteristics of distribtution,association and ratios of trace elements of each epochs of pyrites in different modes of occurrences,sizes and fractions,crystal forms,cataclastic degree,as well as Au distribution in galena of two epochs and in limonite and pyrolusite on the surface,have been systematically studied by comparison of altered rock type with gold bearing quartz vein type gold deposits.Mineral indicators of two types of gold deposits for prospecting have been discussed in this paper.
