“…The Zhongdian arc, which is the southern part of the Yidun arc, contains many Late Triassic intermediate-felsic porphyritic intrusions and associated andesites. The porphyries host porphyry Cu deposits, including the Pulang, Xuejiping, Chundu, and Lannitang deposits (Hou et al, 2004b(Hou et al, , 2007Li et al, 2011;Ren, 2011;Wang et al, 2011;Leng et al, 2012;Chen et al, 2014). In addition, several Late Cretaceous Mo-Cu polymetallic deposits related to the granitic plutons are found in this region, such as in the Xiuwacu, Relin, Hongshan, and Tongchanggou areas Li et al, 2007Li et al, , 2013Meng et al, 2013;H.…”

“…The most prevalent strata are Triassic volcanic rocks intercalated with flysch deposits (BGMRSP, 1991). The Zhongza Massif is commonly thought to have rifted from the western Yangtze block during the opening of the Ganzi-Litang ocean, triggered by the late Permian Emeishan mantle plume (Song et al, 2004;Xiao et al, 2004;Leng et al, 2012;Wang et al, 2013a;T. P. Peng et al, 2014).…”

“…Wang et al (2011) proposed that these adakitic rocks are closely related to interactions between melts of the subducting basaltic oceanic crust and the overlying mantle wedge. However, Leng et al (2012) considered that these rocks originated from a metasomatized mantle with 5-10% crustal contamination. Furthermore, (2014a,b), and this study.…”

Geochronology, mineralogy, and geochemistry of the Late Triassic Xiuwacu biotite granite in the southern Yidun Terrane, southwest China: Insights into the petrogenesis and magmatic fertility

The southern Yidun Terrane formed in response to the westward subduction of the Garzê-Litang oceanic lithosphere. The Xiuwacu pluton, consisting of the Late Triassic biotite granite and Late Cretaceous monzogranite porphyry, is located in the northern portion of the southern Yidun Terrane. It hosts the Late Cretaceous quartz-vein-type Mo-W deposit genetically related to the intraplate monzogranite porphyry. However, the petrogenesis and magmatic fertility of the biotite granite remain unclear. Sixteen zircons from the biotite granite yield a weighted mean 206 Pb/ 238 U age of 217 ± 1.2 Ma, indicating that the biotite granite emplaced synchronously with the arc-related andesites and porphyries in the southern Yidun Terrane. Unlike these slab melt-derived adakitic rocks, the Xiuwacu biotite granites show typical I-type granite affinities, with relatively high SiO 2 contents, low Sr/Y ratios, and high Y contents. These granites display depleted zircon Hf isotopic signatures (ƐHf(t) = 0.6-3.8) but enriched whole-rock Sr-Nd and zircon O isotopic signatures, suggesting that the mixing between juvenile materials and external enriched melts might have contributed to the generation of biotite granite. Moreover, they show relatively high Al 2 O 3 / (FeO T + MgO + TiO 2 ), Th/Yb, and Th/Nb ratios, which are collectively indicative of the input of sediment melts extracted from subducting slab into the melt source of biotite granite. The high MgO, TiO 2 , F, and Cl contents of biotite and the excess Al of plagioclase suggest that the Xiuwacu biotite granites formed under high oxygen fugacities, magmatic water contents, and volatiles components and they might have Cu prospecting potentials.
