Metallogenesis of stratiform Cu mineralization in the Dabaoshan polymetallic deposit, Northern Guangdong Province, South China

Geochronological, geochemical, and Nd–Hf isotopic constraints on the origin of magmatism in the Dabaoshan ore district of South China

“…210 Ma), and Yanshanian (147–168 Ma) periods. Previously published Re–Os ages for molybdenite (163.2 ± 2.3 to 166.6 ± 0.8 Ma; C. Y. Li et al, ; J. W. Mao, Xie, Li, Zhang, & Mei, ; Qu et al, ; L. Wang et al, ) and 40 Ar/ 39 Ar ages for sericite from the porphyry‐ and skarn‐type Mo–W orebodies, as well as the stratiform Cu–Pb–Zn orebodies in this deposit (161.7 ± 1.7 to 167.0 ± 2.0 Ma; Qu et al, ), are consistent with the timing of Yanshanian magmatic activity. Thus, some researchers have suggested that the Mo–W and Cu–Pb–Zn mineralization in the Dabaoshan ore district are the products of just one mineralization event.…”

“…It is a large‐sized polymetallic deposit consisting of stratiform Cu–Pb–Zn, porphyry‐type Mo (W), skarn‐type Mo–W and stratiform siderite orebodies, as well as gossan formed by weathering processes (X. S. Liu & Zhou, ). Previous studies have focused mainly on its geological characteristics, geochronology, ore‐forming conditions, ore‐forming mechanisms and metallogenic models (e.g., Cai & Liu, ; Ge & Han, ; C. Y. Li et al, ; G. Q. Liu, Yang, Zhang, & Cheng, ; W. Mao, Li, & Yang, ; W. Mao, Rusk, Yang, & Zhang, ; Qu et al, ; L. Wang et al, ; Wu et al, ; Yang, ; Ye et al, ; Ying et al, ). The porphyry‐ and skarn‐type Mo–W mineralization was most likely associated with the Jurassic granodiorites/porphyries (e.g., Cai & Liu, ; G. Q. Liu et al, ; L. Wang et al, ).…”
