摘要
The Xinsheng tin-copper polymetallic deposit in Yongxin County,Hunan Province is one of the typical skarn deposits in the Nanling area.Its orebodies occur in the wall rock,skarn and granite bodies.Granite bodies are not exposed on the surface,but concealed bodies exist there,which may be connected with the Dayishan granite bodies at depth.Geochemical characteristics of granite bodies in the Xinsheng ore district indicate K/Rb value is less than 100,and strong magmatic differentiation may be favorable to ore formation.The deposit is controlled by structural features,and the intrusion of magma which contains such ore-forming elements as Cu and Sn,and volatile components F is the most significant ore-controlling factor.
