Genesis of the giant Caixiashan Zn-Pb deposit in Eastern Tianshan, NW China: Constraints from geology, geochronology and S-Pb isotopic geochemistry

Petrogenesis of the Carboniferous Intrusive Rock in the Xiaobaishitou District of East Tianshan, Northwest China: Magma Evolution and Tectonic Significance

“…7). The results of this study and previously published zircon U-Pb data in the CTT demonstrate that a major episode of magmatism occurred in Carboniferous time (Table 1), such as the Caixiashan monzonitic granite (330.0 Ma; Gao et al, 2020), Dayanchi granodiorite (323.1 Ma; Wang D G et al, 2006b), Shaquanzi gabbro (307.2 Ma;Lu et al, 2017), Dayanchi diorite (303.0 Ma; Wang D G et al, 2006a), and Hongyuan granodiorite (301.2 Ma; Lu et al, 2017). In addition, the granodiorite along S301 Road from Baluntai Town to Tuokexun County (353.9 Ma and 353.6 Ma; Yin et al, 2011) and the granitoids along the Qiongkushitai River (325 Ma and 322 Ma; Long et al, 2011) are distributed in the western section of the CTT.…”

Petrogenesis of the granitoids related to skarn-type mineralization in the Nyainqentanglha Metallogenic Belt, Tibet

“…In the paper, we tested four samples of granite porphyry from the Narusongduo skarn deposit for whole-rock geochemistry. We supplemented the data published in the literature to make the data statistically significant (see Table S1 ; [ 12 , 13 , 32 ].…”

“…The Central Lhasa Subterrane consists of extensive Carboniferous-Permian metamorphic strata, Lower Cretaceous volcanic-sedimentary strata, Upper Jurassic-Lower Cretaceous sedimentary strata interbedded with abundant volcanic rocks, and widespread Mesozoic felsic magmatism and Paleocene-Eocene felsic magmatism as described by Ref. [ 12 ]. The northern Lhasa Subterrane is dominated by a juvenile crust composed of Jurassic-Cretaceous sedimentary rocks, Early Cretaceous volcanic rocks and associated granitoids.…”

“…The petrographic descriptions provided in this study are based on previous research conducted by Refs. [ 12 , 13 , 32 ]. Among these deposits, the Narusongduo deposit mainly includes two types of mineralization: cryptoexplosive-breccia and skarn.…”

“…The NMB mainly consists of skarn-type deposits formed at the contact zone between the Paleocene-Eocene intrusive and carbonate/volcanic-sedimentary strata [ [11] , [12] , [13] ]. In recent years, crypto-explosive breccia-hydrothermal vein deposits have been discovered in the Paleocene-Eocene Linzizong volcanic rocks [ 9 , 14 , 15 ]; Qin et al, 2022) ( Fig.…”
