The Yili Basin in NW China preserves a late Paleozoic volcano-sedimentary succession, the provenance of which helps to constrain the tectonic evolution of the South Tianshan orogenic belt. U-Pb ages and trace-element and Hf isotopic compositions of detrital zircons from the Late Devonian to earliest early Carboniferous strata in the Yili Basin suggest that the unit contains detritus mainly derived from basement rocks and contemporaneous arc-related volcanic rocks.

“…If the δ 18 O values of magnetite are beyond this range, it may be suggestive of another origin, for example, recrystallization or hydrothermal alteration mineralization process. The relatively wide range of δ 18 O values in the magnetite from Beizhan deposit is similar to that of magnetite in Zhibo deposit, Chagannour deposit in China, and Kiruna, Sweden, all of which show most plots fall outside of the range (1–4‰; Jiang et al, ; Jonsson et al, ). The δ 18 O values of the samples in this study contrast to that of magnetite with magmatic origin in El Laco, Chile (Jonsson et al, ).…”

“…Although much more attention has been paid to the submarine volcanic‐hosted iron deposits in recent years in AIMB, NW China, several important issues remain debated and are poorly understood. For example, most researchers attributed the submarine volcanic‐hosted iron ores to a volcanic magma origin (e.g., D. H. Wang et al, ; B. Y. Wang et al, ; Yao, Wang, Du, Lin, & Song, ) or of magmatic origin and a late hydrothermal alteration (Duan et al, ; Feng et al, ; Jiang et al, ; Jiang, Zhang, Wang, Li, & Tian, ; Z. H. Zhang, Hong, Jiang, Duan, Wang, et al, ; Z. H. Zhang, Hong, Jiang, Duan, Xu, et al, ; Z. H.

The Carboniferous Beizhan iron deposit is the largest submarine volcanic‐hosted iron deposit in the Awulale Iron Metallogenic Belt of the Western Tianshan. The magnetite‐dominated orebodies occur as lensoid, veined, and stratiform shape in the Dahalajunshan Formation which was intruded by basic‐acid intrusions. Skarn and carbonatization alteration are well developed around the orebody. The genesis of iron mineralization in Beizhan remains controversial. The calculated δ18O values of magnetite using the fractionation factor correspond to (or higher than) the range of common magmatic waters, as well as the δ18O values of alteration minerals (4.0–7.6‰) and intrusions (3.1–8.3‰), indicating magnetite and alteration minerals precipitation from magmatic hydrothermal fluids. The δ34S values of sulphides (pyrite and pyrrhotite) range from 1.0‰ to 6.4‰, supporting a magmatic hydrothermal origin for sulphur. Meanwhile, the Pb isotope compositions of iron ores overlap that of altered rock and intrusions, and the 187Os/188Os ratio of iron ores range from 1.5835 to 2.8452, in accordance with that of intermediate‐acid intrusions (e.g., K‐feldspar granite porphyry and syenodiorite), suggestive of magmatic hydrothermal fluids involved in the mineralization process. Furthermore, the magnetite from the ores shows higher MgO and MnO contents and lower content of TiO2. Pyrite samples from the ores show >570 ppm Co and Co/Ni ratios between 2.53 and 4.23. These features strongly point to a magmatic hydrothermal origin. Combined with previous studies, we propose that the submarine volcanic‐hosted Beizhan iron deposit is analogous to a skarn origin, driven by late‐stage hydrothermal fluids which originated from intermediate‐acid intrusions in the immediate vicinity.

“…The Awulale iron ore belt discovered in recent years is hosted in the Dahalajunshan Formation volcanic rocks. The age of the surrounding rocks in the main iron ore deposits shows that the Dahalajunshan Formation formed in the Early Carboniferous (e.g., the ages of the Zhibo iron ore deposit are 328.7 and 329.9 Ma, Jiang et al, ; the age of the Chagangnuoer iron ore deposit ranges between 350 to 330 Ma, Zhang et al, ; the age of the Songhu iron ore deposit is 343 Ma, Han, Gong, Cheng, et al, ; Han, Gong, Ma, et al, ; the age of the Beizhan iron ore deposit is 335 Ma, Han, Gong, Cheng, et al, ; the age of the Nixintage iron ore deposit is 343 Ma, Jing et al, ).…”

“…Recently, there have been lots of published data on the petrogenesis, age, and metallogenic tectonic background of ore‐bearing volcanic rocks in the Awulale iron ore belt. In summary, most of these researchers believed that the ore‐bearing volcanic rocks formed in an epicontinental arc tectonic setting (Duan et al, ; Han, Gong, Cheng, et al, ; Han, Gong, Ma, et al, ; Jiang, ; Jiang et al, ; Li, ; Li, Gong, et al, ; Li, Wang, et al, ; Song et al, ; Wang & Jiang, ; Xue et al, ; Zhang et al, ; Zhang et al, ; Zhao et al, ).…”

Sr–Nd isotopes of Early and Late Carboniferous volcanic rocks in Yining Massif (Xinjiang, NW China): Implications for petrogenesis and tectonic evolution of Western Tianshan

The Yining Massif, sandwiched between the Junggar and Tarim plates, has received much attention because of its special position and complex tectonic evolution, as well as a significant breakthrough in geological prospecting. Moreover, a lot of studies have focused on two suites of volcanic rocks of the Early Carboniferous Dahalajunshan and Late Carboniferous Yishijilike formations in the Yining Massif. Recently, an increasing number of results have shown that two suites of volcanic rocks have obvious differences in lithochemistry and geochemistry and might have formed in an arc and intracontinental rift settings, respectively. Furthermore, the latest results of Sr–Nd isotopes indicate that the initial (87Sr/86Sr)i ratio is less than 0.7119 for all samples in the two formations. But the (87Sr/86Sr)i of andesites in the Dahalajunshan Formation is obviously higher than that of the Yishijilike Formation. However, those of dacites and rhyolites are just the opposite. The (143Nd/144Nd)i of all kinds of rocks from the Dahalajunshan Formation is less than 0.5126, and that of basalts in Yishijilike Formation is also less than 0.5126. However, the results of the andesites and rhyolites are higher than 0.5126. In short, the parameters of (87Sr/86Sr)i, (143Nd/144Nd)i, εNd(t), TDM (Ga), and εSr(t) are different obviously between the two suites, showing progressive change from basic to acid rocks in the two formations (gradual increase and decrease), but the changed direction is just the opposite. Consequently, it illustrates that there is a significant distinction in composition and petrogenesis between the Dahalajunshan and Yishijilike formations. The Dahalajunshan Formation volcanic rocks might be derived from an enriched mantle, whereas the volcanic rocks in the Yishijilike Formation are related to the evolution of continental crust. In other words, the differentiation of Sr–Nd isotopes provides a reference information for studying the petrogenesis and tectonic setting of the two suites of volcanic rocks.
