摘要
Shixing,Guangdong Province,is one of important tungsten polymetallic ore concentrated area in Eastern Nanling mineralizationzone.Two large deposits,ie.Liangyuan Nb-Ta-W-Sn and Nanshankeng W-Sn polymetallic deposit,were found by Nanjing Center,CGS during the investigation of tungsten polymetallic ore in this area.The W and Mo polymetallic deposits occurred in granite complex of Yanshan period,Nb,Ta,W and Sn polymetallic deposit in greisen and highly evolved muscovite albite granite,and stratabound skarn type W and Sn polymetallic deposits in the upper Devonian strata.This article further defines the characteristics of W and Mo polymetallic deposit in the granite,Nb-Ta-W-Sn polymetallic deposit in the greisen and albite graniter,and skarn type W-Sn polymetallic deposit in Shixing and summarizes prospecting procedure and method and as well metallogenic model for the W-Sn polymetallic ore in eastern Nanling.
