摘要
By the field geological survey of the rocks,silicate full analysis,trace elements analysis and LA-ICP-MS zircon U-Pb dating,the authors explore the dynamics environment of the granite from the Huanggoushan area in the south of Jilin Province of China. On the primitive mantle-normalized spider diagrams,the granites show positive K,Rb and Th anomalies and negative Ba,P,Ti,Nb,Ta anomalies,having the geochemical characteristics of an active continental margin magmatic arc,and their formation is related to the subduction of the ancient Pacific plate to North China plate.
