摘 要:在介绍石湖金矿地质概况的基础上,详述了围岩蚀变和成矿地球化学特征,从而总结出成矿演化规律和矿化空间富集规律及综合找矿标志,指出了进一步找矿的有望地段。
Abstract: Shihu gold deposit occurred in the Archean metamorphic rocks and lodes 101, 102,115,116 have been found.With the mineralization in the country rocks the alteration mineralspyrite,quartz, sericite,K-feldspar,chlorite and locally carbonate minerals and kaolinite,etc. developed.The mineralization could be divided into 4 stages, and most of the gold de-posited in Ⅱ,Ⅲ stages.Where the supercatoclasite devoloped,the different orientationalfaults crossed, and the occurrace changed in the same fault belt, the rich gold ores could befound. Therefore , based on the demonstration of the metallogenic evolutionary regularitiesin the temporal and the mineralizational enrichment pattern in spatial,as well as the explo-rationary marks,it has been point out that the hopeful districts for the future prospecting forgold are(1)the vein 90, northern end of the lode 101;(2)the deep on45 degree dip of thesouthern part of lode 101; (3)around the No, 11 exploration line of the lode 102.
