“…Early Paleozoic granitoids intruding into the Precambrian rocks mostly occur in the NYGB to the CTGB. For example, granitoids collected from the Wenquan area in the northern part of the NYGB yielded zircon ages of 447 Ma to 466 Ma Wang et al, 2012), whereas granitoids in the SYGB yielded ages between 426 Ma and 523 Ma (Li, 2011a;Long et al, 2007b;Qian et al, 2009;XBGMR, 1993;Xu et al, 2010;Yang and Zhou, 2009;Zhu et al, 2006). In the CTGB, granitoids yielded zircon ages of 416 Ma to 479 Ma (Gao et al, 2009b;Han et al, 2004;Li, 2011a;Long et al, 2007b;Shi et al, 2007;Xu et al, 2006bXu et al, , 2010Yang et al, 2006).…”

“…This is supported by recent studies elsewhere in the northwestern Chinese Tianshan. In the northern part of the NYGB, arcrelated early Paleozoic granitoids were described in the Wenquan area and yielded zircon U-Pb ages of 466-447 Ma Wang et al, 2012). Similar granitoids in the SYGB and CTGB provided zircon U-Pb ages of 523-424 Ma and 479-416 Ma, respectively (Gao et al, 2009b;Han et al, 2004;Li, 2011a;Long et al, 2007b;Qian et al, 2009;Shi et al, 2007;XBGMR, 1993;Xu et al, 2010;Yang and Zhou, 2009;Yang et al, 2006;Zhu et al, 2006).…”

“…This suggestion is supported by the following evidence: (1) The early Paleozoic accretionary complexes and magmatic rocks in our study area indicate that the Junggar Ocean was subducted beneath the Yili Block; (2) A magmatic belt developed in the Chinese northwestern Tianshan (Gao et al, 2009a;Long et al, 2011a;XBGMR, 1993); (3) Early Paleozoic basalt and andesite in the southern Tianshan formed in a back-arc tectonic setting (Lei et al, 2011;Wang et al, 2011a); (4) Top-to-north ductile shearing foliation preserved in rocks of the Yili Block implies a southward subduction polarity of the Junggar Ocean (Charvet et al, 2007;Gao et al, 2011;Wang et al, 2012); (5) The 418-460 Ma mylonites in the Northwestern Chinese Tianshan (Yao et al, 2008) possibly result from southward subduction of Junggar Ocean which gave rise to metamorphism and deformation of protoliths in a compressional and thermal condition. Depending on previous studies, north-west trending accretionary wedges occur from the southern West JunggarNorth Balksh to East Kazakhstan (Windley et al, 2007).…”

Some early Paleozoic ages (447)(448)(449)(450)(451)(452)(453)(454)(455)(456)(457)(458)(459)(460)(461)(462)(463)(464)(465)(466) were recently obtained for granitoids exposed in the Wenquan area Wang et al, 2012). These magmatic rocks are generally considered to have a close relationship to subduction of the Junggar Ocean, but their petrogenesis and tectonic setting are poorly studied.…”

Geochronological, geochemical, and Sr–Nd–Hf isotopic studies of the Aketas adakitic granites in Eastern Junggar: Petrogenesis and tectonic implications

et al. 2017

The Aketas adakitic granites are located in the Dulate Arc, in the northern part of the eastern Junggar region, Xinjiang (NW China). In this study, we determined the zircon U-Pb isotopic compositions, bulk-rock Sr-Nd-Hf isotopic compositions, and major and trace elements of Aketas granite samples. Sr ratios (0.70298-0.70350) and positive εNd(t) (+5.1 to +7.0) and εHf(t) values (+10.4 to +14.9) suggest that the Aketas adakitic granites were derived from the partial melting of lower crustal material in a subduction setting. This is further evidenced by high Mg# values (42.00-65.67), high SiO 2 and K 2 O content, and low Cr (<17.30 ppm), Co (<9.62 ppm), and Ni (<12.60 ppm) content. Bidirectional subduction occurred between eastern Junggar and the Altai Orogen during the Late Carboniferous, and in combination with other exposed Palaeozoic granites in eastern Junggar, the Aketas adakitic granites may represent the latest record of this subduction event. The emplacement of the Aketas adakitic granites implies that eastern Junggar was involved in southward subduction at 308 ± 2.3 Ma; therefore, the final collision between the Siberian and Kazakhstan blocks likely occurred between 310.3 and 307 Ma.

The Tulasu Basin is an important epithermal gold ore cluster situated in the Boluokenu Polymetallic Belt, Western Tianshan, China. The Axi Au, Tabei Pb–Zn, and Tawuerbieke Au deposits in this basin represent different types of epithermal mineralization. These are products of the same tectonic‐magmatic‐hydrothermal event, related to the southward subduction of the North Tianshan Ocean beneath the Yili‐Central Tianshan Plate during the Late Devonian to Early Carboniferous. The spatial relationships, preservation levels, and evolution of the three deposits are still debated. Hence, systematic geological field investigations, ore microscopy, and isotopic analyses were carried out on these three deposits. The S–Pb–C–H–O isotopic compositions indicate that the ore‐forming components were derived from the volcanic‐subvolcanic rocks, as well as from circulating meteoric waters. The occurrence of adularia, silicified platy carbonates, and quartz characterized by crustiform/colloform/colloidal textures at Axi indicate that boiling was the main precipitation mechanism for the Au mineralization. The Pb–Zn ores from Tabei are characterized by abundant banded coarse‐grained quartz crystals with dog tooth and comb textures, suggesting that the sulphides precipitated slowly due to conductive cooling. The Tawuerbieke Au deposit is characterized by pervasive silicification and phyllic alteration accompanying veinlet and disseminated ore, which formed via metasomatic water–rock interaction. According to the ore textures, intrusion sizes, and mineral assemblages, it can be inferred that all three deposits experienced different extents of erosion (Axi < Tabei < Tawuerbieke) and that there is exploration potential for concealed porphyry Cu–Au mineralization. Exploration should focus on deep targets beneath the Tawuerbieke Au deposit.
