摘要
In this paper,the authors present U-Pb age,geochemical,and Sr-Nd-Hf isotopic data to provide, constraints on the age and petrogenesis of the Ruanjiawan and Xiuniushan intrusions and discuss their potential forming porphyry Cu deposits.The high oxygen fugacity,high contents of volatile component,and the occurrence of porphyry Cu spots in the Xiniushan granodiorite porphyry suggest great potential finding porphyry-type deposits in the intrusion.
