Geochemical and Sr-Nd-Hf isotopic compositions of granodiorite from the Wushan copper deposit, Jiangxi Province and their implications for petrogenesis
|
Abstract:
Wushan deposit is a large copper deposit located in the Jiu-Rui mineralization concentrated area in the Middle and Lower Yangtze Reaches,south China.In this study,we report mineral chemistry,major,trace elements,and Sr-Nd-Hf isotopic compositions of the ore-related granodiorite at Wushan.The biotites are Mg-riched and belong to phlogopite,which Fe~(3 +)/Fe~(2 +) ratios indicating a high oxygen fugacity (f_(02)) for the magma.The amphiboles show high Mg/(Mg + Fe) and low Si,and belong to actinolite and magne...
