“…These magmatic activities are divided into four stages according to the U–Pb ages of the granitic plutons: the Late Devonian stage (386–369 Ma), the Early Carboniferous stage (349–330 Ma), the Late Carboniferous to Late Permian stage (320–252 Ma), and the Early Triassic stage (246–230 Ma; Zhou et al, and detailed references therein). The three early stages of the magmatic activities tend to be longer lasting and more intense from the first to the third stage (Zhou et al, ), and the granitoid activity in the fourth stage became weak and scattered mainly in the east of the Jueluotage belt (Deng et al, ; Lei et al, ; Wu et al, ; Zhang, Liu, et al, ; Zhou et al, ).…”

The Bogda Mountains, situated in the southern part of the Central Asian Orogenic Belt (CAOB), is an important intraplate orogenic belt for studying the Mesozoic tectonic evolution mechanism of the CAOB. The detailed palaeogeographic evolution process of the Bogda area during Early Jurassic times remains poorly understood. The sandstone petrography, sedimentary rock geochemistry, and detrital zircon U–Pb geochronology were integrated to research the provenance of the Lower Jurassic Badaowan and Sangonghe formations clastic rocks from the northern flank of the Bogda Mountains and further constrain the palaeogeographic evolution of Bogda Mountains. The petrological and geochemical data in this study indicate that the Lower Jurassic sediments were derived from a felsic source area. Compared with the Badaowan Formation, the source rocks for the Sangonghe Formation show more mafic characteristics. U–Pb age patterns of the Badaowan Formation have multiple age groups, and most of the zircon ages are concentrated in the Carboniferous and Late Permian–Early Triassic ages. The Late Permian–Early Triassic age group disappears in the U–Pb age spectrum of the Sangonghe Formation, and every peak age is 20–50 Ma younger than those of the Badaowan Formation. Combined with the compiled sedimentary facies and paleocurrent data, the felsic‐intermediate volcanic rocks and granitoid intrusions in the Harlik arc and the east of the Jueluotage belt were the predominant sources of the Badaowan Formation, and then the dominant source changed to the bimodal volcanic rocks in the Eastern Bogda Mountains during the Sangonghe Formation deposition period. Early Mesozoic palaeogeographic evolution of the Northern Tianshan belt is speculated: (1) the paleotopography of the Jueluotage belt had a differential uplift along its strike, transforming from high in the west during Triassic times to high in the east during early Early Jurassic times and (2) the Eastern Bogda Mountains initiated uplift during late Early Jurassic times.

“…The intrusive rocks outcropped in the Huangtupo–Honghai, Meiling, Hongshi, Yudai, and Xierqu mining district. The intrusive rocks comprise mainly Ordovician–Silurian diorite (452–430 Ma; Deng et al, ; Du et al, ; Zheng et al, ) and diorite porphyry (443–437 Ma; Du et al, ), Silurian granite (435 ± 2 Ma; Zheng et al, ), and diorite porphyry (390–382 Ma; Mao et al, ). The exploration of Cu deposits in the Kalatag area began in 2000 and resulted in the discovery of the Hongshan, Hongshi, and Meiling, Yudai, Huangtupo–Honghai Cu polymetallic deposits (Mao et al, 2010; Figure ).…”

“…The exploration of Cu deposits in the Kalatag area began in 2000 and resulted in the discovery of the Hongshan, Hongshi, and Meiling, Yudai, Huangtupo–Honghai Cu polymetallic deposits (Mao et al, 2010; Figure ). The geochronological data suggest several distinct metallogenic events in the Kalatag area as follows: (a) porphyry‐type Cu deposits (449 Ma; represented by Yudai; Sun et al, ), (b) VMS‐type Cu–Zn deposits (443–434 Ma; represented by South Meiling, Deng, Wang, Santosh, et al, ), (c) hydrothermal vein Cu deposit (431 Ma; represented by Hongshi; Deng et al, ), (d) skarn Cu–Fe deposit (382 Ma; represented by Xierqu; Mao et al, ), and (e) hydrothermal vein Cu deposit (~300 Ma; represented by Meiling and Hongshan; Deng et al, ). These deposits mainly formed during three episodes: 450–430, 400–380, and 308–300 Ma, respectively.…”

The Early Palaeozoic granitoid rocks represent a volumetrical component of the eastern part of the Dananhu–Tousuquan island arc belt of the East Tianshan and preserve useful information about the tectonomagmatic history of this region. The Hongshi intrusion primarily consists of granodiorite, which intrudes the Ordovician–Silurian Daliugou Formation in the Kalatag area. Zircon U–Pb dating of magmatic zircons from the granodiorite was formed at 426.6 ± 2.3 Ma, suggesting that the intrusion was emplaced in the Middle Silurian. Geochemically, granodiorite belongs to the metaluminous calc‐alkaline I‐type granitoids associated with a narrow range of SiO2 concentration (63.53–67.71 wt.%), A/CNK values ranging from 1.01 to 1.12. They have high Ba, LREE, and LILE contents and low abundance of HREE and HFSE. These samples displayed MgO contents of 1.38–1.52 wt.%, resulting in low K2O/Na2O ratios of 0.11–0.33 and intermediate Mg# values of 29.03–37.31, with high Sr/Y, La/Yb, and Ba/Th ratios, positive εNd(t) (6.60 to 7.95) and εHf(t) (13.1–16.0), low (87Sr/86Sr)i (0.704113–0.704312), and low Nb/U and Ta/U ratios. These features indicated that the parental magma of the granodiorite was probably derived from a juvenile crust with no significant mantle component involvement. Based on the regional geology and geochemical evidence, the Hongshi granodiorite is considered to have formed in an arc setting, associated with the northward subduction of the young Kangguer Ocean slab beneath the Dananhu island arc.

The Early Paleozoic volcanic rocks of Daliugou Formation at the southern margin of the Turpan‐Hami Basin in the eastern Tianshan Orogen host important volcanogenic massive sulfide (VMS) deposits. Here, we report zircon U–Pb ages of dacite and tuff from the hangingwall and footwall of the VMS deposit, and granodiorite that intruded the volcanics. Our data reveal that the dacite crystallized at 441.4 ± 2.6 Ma and carry older xenocrysts of 2,664, 1,854, and 1,074 Ma. Zircons in the intensively altered tuff crystallized at 440.4 ± 2.9 Ma, with inherited grains of 2,517.4 ± 31.9, and 782.9 ± 11.1 Ma. Zircons in the granodiorite yield a weighted mean age of 430.0 ± 1.7 Ma. The volcanics in the Daliugou Formation evolved from basaltic andesite (>450 Ma) and tuff (450–440 Ma) to dacitic lava (440–420 Ma). We envisage a subduction‐related tectonic setting for the Daliugou Formation rocks when the eastern Kalatag area transformed from an island arc before 450 Ma, through back‐arc basin during 450–440 Ma, to island arc during 440–420 Ma.
