Abstract:In recent years, strongly polymetallic mineralization are found in greisen beside the quartz vein type tungsten in Shirenzhang. By means of electron probe and scanning electron microscop and energy dispersive spectrum analysis, silver content in greisen in an averge of 309.22×10-6, 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 illustrate that greisenization plays a significant role in mineralization.
