摘要
贵州册亨县尾若金矿产于北东向F_2断裂破碎带内,含金地层为三叠系许满组,矿化围岩为泥灰岩、泥质粉砂岩,围岩蚀变有硅化、黄铁矿化、碳酸盐化、黏土化、毒砂化、脱钙;矿体呈扁豆状、透镜状、脉状产出,矿化体(带)长200m,矿化带(体)水平厚度1.00m^5.20m,平均品位Au为0.50×10^(-6)~6.37×10^(-6)。
The Weiruo gold ore in Ceting County of Guizhou Province is produced within NE trend F_2 faulted fracture zone,the gold-bearing beds belong to Xuman Group of Triassic System,the mineralized surrounding rocks are mud-limestone and argillaceous siltstone,and the alteration of surrounding rocks includes the siliconization,pyritization,carbonatization,argillization,arsenopyritization and decalcification;the ore body presents the lenticular,lenticular and vein output,the length of mineralized body（belt） is 200 m,the the level thickness of mineralized belt（body） is 1.00 m-5.20 m,and the average grade of Au is 0.50×10～（-6）-6.37×10～（-6）.
