石人嶂钨矿床云英岩型矿化及其研究意义
|
摘要
石人嶂石英脉型钨矿脉旁侧的云英岩有很强的多金属矿化。通过电子探针和扫描电镜能谱分析发现,云英岩中银平均含量为309.22×10-6,达到了综合利用的伴生银品位要求,Mo、Cu、Sn等元素含量也很高;云英岩中放射性元素含量[U(24.14×10-6),Th(46.30×10-6)]远大于花岗岩和石英脉中放射性元素的含量,呈现出了放射性元素富集的现象;云英岩的刻槽取样分析,进一步说明了云英岩化对矿化的重要作用。
In recent years,strongly polymetallic mineralization is found in greisen beside the quartz vein type tungsten in Shirenzhang.By means of energy dispersive spectrum analysis with electron probe and scanning electron microscop,it's found that silver content in greisen is an average of 309.22×10-6,which achieves the tenor requirements of associated silver for comprehensive utilization.Mo,Cu,Sn and other elements contents are also very high.Radioactive elements contents(U(24.14×10-6),Th(46.30×10-6))in greisen are far greater than that in granite and quartz vein,showing the phenomenon of radioactive elements enrichment.The channel sampling analysis of greisen further illustrates that greisenization plays a significant role in mineralization.
