ABSTRACTThe Ganzi–Litang fault zone, an outstanding tectonic element in the eastern Tibetan Plateau has been intensively debated as an in-situ suture zone marking relict of a subducted Palaeo-Tethyan oceanic crust or a failed intracontinental rift. This paper reports the garnet amphibolites discovered along the Ganzi–Litang fault zone, eastern Tibetan Plateau. These garnet amphibolites are characterized by the garnet–hornblende–rutile–sphene–plagioclase–quartz assemblage. Conventional geothermob...

Abstract The Gongcai and Qinganlin plutonic complexes in the Danba Domal Terrane, eastern Songpan-Ganze Fold Belt, consists of ca. 860 Ma adakitic tonalities and ca. 830 Ma high-K granites, respectively. Samples from the Gongcai complex have variable SiO 2 (66.7–72.1 wt%), high Al 2 O 3 (14.3–17.7 wt%), low alkalis (5.71–7.07 wt%), and high Sr (576–1309 ppm) and low Y (2.2–10.4 ppm) contents, similar to typical adakites. The Qinganlin complex possesses higher SiO 2 (70.9–73.3 wt%) and lower Al 2...

Abstract Studies on zircon ages, petrology, major and trace element geochemistry, and Sr–Nd–Hf–Pb isotopic geochemistry of intermediate volcanic rocks from the Southern Yidun arc, Sanjiang-Tethyan Orogenic Belt, SW China have been undertaken in this paper. They are used to discuss the petrogenesis of these rocks and to constrain the tectonic setting and evolution of the Yidun arc. These intermediate volcanic rocks were erupted at ca. 220 Ma (U–Pb zircon ages). Trachyandesite is the dominant lith...

Abstract Zircon U–Pb ages and Hf isotopic composition of Mesozoic intrusive rocks from the Yidun terrane were systematically investigated in order to decipher the geodynamic setting of magmatism and their relationship with Cu-polymetallic mineralization in the Eastern Tibetan Plateau. Zircon U–Pb dating results on seven granitoid rocks and four diorite samples indicate that the Mesozoic plutons from the Yidun terrane were emplaced in the period of 224–214 Ma with a peak at ∼216 Ma. Zircon Hf iso...

We conducted in situ U–Pb and Lu–Hf isotope analyses of 401 detrital zircons collected from the Songpan–Ganzi Triassic turbidite complex in an attempt to understand the provenance variations of the siliciclastic rocks and the crustal growth history of central China. These detrital zircons exhibit a wide age spectrum with three major peaks at 1.7–2.0 Ga, 750–1050 Ma, and 210–500 Ma. They are dominated by negative ϵHf(t) values with a large range. Synthesis of the zircon U–Pb and Lu–Hf isotopic da...

Abstract The Yidun Group extends from the Shangri-La region to the south and the Changtai region to the north, and is an important component of the Triassic Yidun arc in the eastern Tibetan plateau. It is composed of the Lieyi, Qugasi, Tumugou and Lanashan Formations from the base upward. Both the Lieyi and Lanashan Formations consist dominantly of black or gray slate and sandstone, whereas the Qugasi and Tumugou Formations have variable amounts of mafic to felsic volcanic rocks and tuffs accomp...

Abstract Triassic Paleo-Tethyan subduction-related volcanic rocks are extensively distributed in the Xiangcheng and Changtai regions, northern Yidun Terrane, eastern Tibet. The ~ 228 Ma volcanic rocks in the Xiangcheng region have intermediate-felsic composition (60.1 to 64.7 wt.% SiO 2 ) with relatively low Y (14–18 ppm) and high Sr (630–1830 ppm) yielding high Sr/Y ratios (43–94). They have LREE-enriched and HREE-depleted REE patterns (La/Yb = 19–26), typical of adakites. Sr–Nd isotopic compos...

Abstract The Garze–Litang suture zone, located in the eastern part of the Tethyan tectonic domain, is notable for widespread Late Triassic granitic plutons, which are genetically associated with the evolution of the Paleo–Tethys Ocean. The Daocheng granitic pluton in the eastern Yidun Arc, SW China, is located in the middle of the Garze–Litang suture zone and has an outcrop area of ∼2800 km 2 . In the present study, we report zircon U–Pb ages and elemental and Sr–Nd–Hf isotopic data for the Daoc...

Abstract The Xuejiping porphyry copper deposit is located in northwestern Yunnan Province, China. Tectonically, it lies in the southern part of the Triassic Yidun island arc. The copper mineralization is mainly hosted in quartz-dioritic and quartz-monzonitic porphyries which intruded into clastic-volcanic rocks of the Late Triassic Tumugou Formation. There are several alteration zones including potassic, strong silicific and phyllic, argillic, and propylitic alteration zones from inner to outer ...
