Abstract Highly evolved granites are an important type of granitic rock given their close relationship with W–Sn–Nb–Ta and rare-metal mineralization and unusual geochemistry. Compared with typical granites, highly evolved granites experience a more complex magmatic evolution, which is difficult to investigate with whole-rock analyses. In this paper, we present a comprehensive major and trace element (including halogen) dataset for biotites from highly evolved granites in the Shimensi ore deposit...

Abstract In this study, we explore the chemistry of accessory apatite and zircon as tools to monitor the petrogenetic and metallogenetic processes involved in the formation of the Wushan Cu- and Zhuxiling W (Mo)-mineralization related granodiorite porphyry. The Wushan granitoids are metaluminous with A/CNK of 0.88–1.01, and the Zhuxiling intrusions are weakly peraluminous with higher A/CNK values (1.02–1.12). The Wushan granitoids have eNd(t) values of −4.6 to −4.7, which, combined with the rela...

Abstract Scheelite is the main ore mineral in skarn-type tungsten deposits, which can be used to track the ore-forming processes and sources. The Zhuxi W-Cu deposit (3.44 Mt WO3 at 0.54% and 0.10 Mt Cu at 0.57%), located in the northern part of the Jiangnan orogen, is one of the largest tungsten deposits in the world. Skarn and orebodies occur mainly within the contact zone between the Mesozoic highly fractionated intrusions and Carboniferous carbonate sediments (Huanglong and Chuanshan formatio...

Abstract Porphyry-type copper mineralization is generally considered to be related to ore-forming fluid exsolution from oxidized, magnetite-bearing intermediate- to felsic magmas. However, copper deposits associated with ilmenite-bearing per-aluminous evolved granites also exist and their origin remains obscure. The Shimensi W-Cu-Mo polymetallic deposit, located in the northern segment of the Jiangnan Orogen (South China) composed mainly of the Neoproterozoic Shuangqiaoshan Group meta-sediments/...
