The Liangyuan Nb-Ta-Rb-W polymetallic deposit in Shixing county, Guangdong Province, a deposit with a prospect of large scale, was found during the new-round investigation of tungsten polymetallic ores in the eastern Nanling mineralization zones deployed by China Geological Survey(CGS)in recent years. The study indicates that the Nb-Ta-Rb-W-polymetallic ore bodies might be originated from the differentiation of deep-seated ore-bearing magma. The Liangyuan Nb-Ta-Rb-W-polymetallic deposit is characteristic of stable-grade, large scale and complex ore-forming elements with a Nb-Ta-Rb-W-Mo-Sn-Bi assemblage, enriched in Be、REE、Ag. The discovery of Liangyuan deposit is not only a breakthrough of prospecting in the eastern Nanling region, but also an important guide in Nb-Ta-Rb-W-polymetallic ore prospecting work in the whole Nanling and even South China.
