Abstract
Abstract The Xinjiang Uygur Autonomous Region in NW China occupies around 1/6 of the total China land size, and contains components of both the Central Asian Orogenic Belt (CAOB) and Paleo-Tethyan Orogenic Belt (PTOB). The Paleozoic CAOB is situated in the northern and central parts of Xinjiang, whilst the Paleozoic-Mesozoic PTOB is mainly located in the southern part of Xinjiang. These orogenic belts were formed by the multiphase Paleozoic-Mesozoic terrane accretions and collisions enacted by the Paleo-Asian Ocean and Paleo-Tethys closure, a process that has also generated many well-endowed tectono-metallogenic belts. From north to south, these belts include the Chinese Altay, the Junggar, the Chinese Tianshan and the Kunlun, Alytn and Qimantage mountains. Since the late 1990s, especially in the past 10 years, many Au, Cu, Fe and Pb-Zn deposits have been discovered. These ore deposits commonly show clear but complex relationships with the orogenic processes. Detailed studies of these mineral systems and their associated magmatic-metamorphic events and structural deformation would significantly improve our understanding of the metallogenic evolution of the CAOB and PTOB in Xinjiang. The 33 papers presented in this special issue, which represents the first collective work of Xinjiang mineral resources in international journals, are aimed to convey the latest research findings on key Au, Cu, Fe-(Cu), Pb-Zn and other metal deposits in Xinjiang. It is our wish that this special issue could enhance our knowledge on the nature and evolution of the metallogenesis in the Xinjiang orogens, and reinforce the foundation for future mineral research and exploration.

Abstract The Boluokenu Range is one of the most important metallogenic belts in northwest China, and it contains numerous Fe, Cu, Mo, Au etc deposits. The Kendenggao’er Cu-Mo deposit is located in the eastern segment of the Boluokenu metallogenic belt within the Western Tianshan orogeny. Skarn and Cu-Mo orebodies occur as lamellae or lenses along the contacts between different units of the Upper Carboniferous Dongtujinhe Formation and the Aimujin granitic intrusions. Based on field investigation...

Abstract The Heijianshan Fe–Cu (–Au) deposit, located in the Aqishan-Yamansu belt of the Eastern Tianshan (NW China), is hosted in the mafic–intermediate volcanic and mafic–felsic volcaniclastic rocks of the Upper Carboniferous Matoutan Formation. Based on the pervasive alteration, mineral assemblages and crosscutting relationships of veins, six magmatic–hydrothermal stages have been established, including epidote alteration (Stage I), magnetite mineralization (Stage II), pyrite alteration (Stag...

The Central Asian Orogenic Belt (CAOB) was the result of long-lived multi-stage tectonic evolution, including Proterozoic to Paleozoic accretion and collision, Mesozoic intracontinental modification, and Cenozoic rapid deformation and uplift. The accretionary and collisional orogenesis of its early history generated a huge orogenic collage consisting of diverse tectonic units including island arcs, ophiolites, accretionary prisms, seamounts, oceanic plateaus and micro-continents. These incorpora...

Abstract The Kalaizi deposit in the Bulunkuole Group of Taxkorgan area, Western Kunlun (NW China) is a unique regional Fe–Ba deposit accompanied with sporadic Fe–Pb–Zn sulfide mineralization within a series of iron deposits. All the ore bodies are stratabound and hosted by the Early Cambrian metamorphosed argillaceous clastic rocks. Here, we analyzed C–S–O–Sr isotopes and trace elements in individual minerals (e.g., magnetite, barite, ankerite) from the Kalaizi deposit to investigate the origin ...

Abstract The strongly deformed Yuleken porphyry Cu deposit (YPCD) occurs in the Kalaxiangar porphyry Cu belt (KPCB), which occupies the central area of the Central Asian Orogenic Belt (CAOB) between the Sawu’er island arc and the Altay Terrane in northern Xinjiang. The YPCD is one of several typical subduction-related deposits in the KPCB, which has undergone syn-collisional and post-collisional metallogenic overprinting. The YPCD is characterized by three pyrite-forming stages, namely a hydroth...

Abstract The Late Triassic Sarekuobu lode gold (Au) deposit (reserves: 8.00 t Au at 3.68 g/t) is situated in the Kelan volcanic basin of the Chinese Altay Orogen, NW China. Gold mineralization is hosted in the deformed metavolcanic sequences of the Devonian Kangbutiebao Formation. Multi-isotope analyses were conducted to constrain the ore-forming fluid and metal sources of the Sarekuobu deposit. The measured δD V-SMOW values of the fluid inclusions from the mineralized quartz (stages II and III)...

Abstract The Zankan iron deposit (Taxkorgan County, Xinjiang) is a recently discovered large Fe deposit in western China. The deposit is hosted in the Bulunkuole metamorphic complex in the Taxkorgan terrane of the West Kunlun Orogen. The ores are uniquely composed of magnetite, pyrite and anhydrite with variable contents, and show massive, disseminated and banded styles. The ores contain widely varying (Al 2 O 3 + TiO 2 ) (0.28–5.48 wt%), Zr (3.0–83 ppm) and Hf ( 2 O 3 contents, as well as Zr vs...

Abstract The Axi deposit is the largest low-sulfidation epithermal gold deposit in Chinese Western Tianshan, Central Asian Orogenic Belt. In this contribution, combined petrological observations, electron microprobe analysis (EMPA) and X-ray backscattered electron images (BSE) have been conducted on Fe-S-As minerals to reveal their textural and compositional evolution. Pyrite and arsenopyrite are ubiquitous. Their texture and composition show gradual changes with time. Four generations of pyrite...

Abstract Western Tianshan along the southwestern margin of the Central Asian Orogenic Belt is well-endowed with epithermal and porphyry Au deposits. The Kuruer Cu-Au deposit, recently discovered in the eastern part of Western Tianshan, was considered as a high sulfidation epithermal deposit. However, our geological, fluid inclusion and stable isotopic studies indicate that it actually formed in transition from high sulfidation to porphyry. The host rocks include the Dahalajunshan Formation volca...

Abstract Although the Eastern Tianshan terrane in Xinjiang, NW China, occupies a critical position in the Central Asian Orogenic Belt (CAOB), the early Paleozoic tectonic evolution and mineralization history of this terrane remain ambiguous. The Yudai deposit is a newly discovered porphyry Cu (Mo, Au) deposit in the Kalatag district of the Dananhu island arc, a key area containing early Paleozoic rocks in the Eastern Tianshan. This paper reports the geologic characteristics, molybdenite Re–Os ag...

Abstract The Tuwu deposit (557 Mt at 0.58% Cu) is the most typical and economically significant one of several porphyry copper deposits in the Dananhu-Tousuquan Arc Belt near the Turpan-Hami Basin, northwest China. The mineralization occurs as chalcopyrite and minor bornite in quartz-bearing veins and host porphyries (i.e. diorite porphyry and tonalite porphyry), and is closely associated with potassic (e.g. K-feldspar, magnetite, and hematite) and phyllic (e.g. sericite, pyrite, albite and chlo...

The Axi gold deposit is one of the largest epithermal deposits in northwestern China and is characterized by multistage generations of pyrite associated with gold mineralization. Genetic models for superjacent epithermal Au and porphyry Cu systems involve either contemporaneous or episodic mineralization, implying different metal sources and ore-forming events. Nine pyrite separates from disseminated ores associated with pyrite-sericite-quartz alteration in the Axi deposit yield a Re–Os isochron...

Geochemical anomalies are commonly separated into different geochemical anomaly levels based on one or more thresholds. However, this practice may cause some important geochemical anomaly information to be lost and subsequently draw wrong decisions for mineral exploration. In addition, previous studies indicate that sparse geochemical sampling always entails uncertainty resulting from conventional geochemical interpolation methods because of smoothing effect. Uncertainty can propagate through th...
