Introduction
My primary research interests focus on tectonics and structural geology, geochronology, sedimentology, and dynamics of orogenic belts and metallogeny in association with accretionary orogenesis. My recent researches include the Altaid collages and Tethyan orogens, and comparative studies across the Phanerozoic orogenic belts. I have published 500 papers in international journals and books. I am co-leader of IGCP 592 and 662. I am Science Editor of GSAB and AE or Topic Editor of several journals.

Full-text available
Much debate exists concerning mechanisms of crustal material transfer from subducting slab to overlying mantle. Formation of mélange rocks by physical mixing of slab components within subduction plate interface is predicted to transfer their compositional signal to source of arc magmas by ascending as diapirs from slab-top. Despite being supported...
Article
Mantle heterogeneity has revealed systematic differences in Pb isotopic compositions between the Indian Ocean-South Atlantic mantle in the Southern Hemisphere and the Pacific Ocean-North Atlantic mantle in the Northern Hemisphere. This large-scale difference in mantle isotopes in the Southern Hemisphere is known as the DUPAL anomaly, but its origin...

中亚造山带在显生宙期间经历了强烈的陆壳增生与改造作用,其地壳增生过程和成矿作用复杂多样。晚古生代的天山以大规模走滑剪切变形、同构造岩浆和多金属成矿作用为显著特征,是中亚造山带增生汇聚作用的典型地区。前人的研究主要关注于剪切带起源与演化时限、变形特征或独立矿床的典例剖析,缺乏针对剪切带演化与成矿时空联系的综合研究。本文选取天山康古尔-黄山剪切带出露的代表性矿床—康古尔金矿和红山南金矿,开展金矿石中绢云母40Ar/39Ar定年研究,并结合前人报道的年代学数据来探讨金成矿与大规模剪切活动的时空联系,从而揭示区域差异性隆升与成矿作用的耦合关系。定年结果显示,康古尔金矿的成矿时代为 264.8 ± 1.7 Ma,而红山南金矿的成矿时代为 261.5 ± 1.5 Ma,与康古尔-黄山剪切带右行走滑运动时...

The late Mesozoic tectonic evolution of the eastern North China craton was intimately related with the subduction of the paleo-Pacific plate. This study sheds light on Late Jurassic−Early Cretaceous basin-mountain coupling during paleo-Pacific subduction based on low-temperature thermochronology and geochemical analyses from the easternmost Yanshan...
Article
Full-text available
Collisional orogeny is characterized by deep subduction of continental crust and major crustal thickening, leading to high-pressure/high-temperature metamorphism and anataxis of the subducted continental crust. Since conductive heating of large slabs of cold, subducted continental crust is a slow process, heating up to a temperature that is high en...
Article
The Early Paleozoic orogeny in eastern South China has been highly controversial. It has been alternatively interpreted to have formed in an intra-plate setting driven by far-field tectonic forces or at plate boundaries involving subduction-collision. The West Cathaysia terrane in the core of the orogen is characterized by extensive magmatism, inte...

The position of South China in Gondwana remains controversial. In all previous models, the Yangtze and Cathaysia blocks, the two major components of South China, were amalgamated by the Tonian, and South China was considered to be a single coherent block in Gondwana. Based on a summary and critical reevaluation of available paleomagnetic, paleontol...

The Altai is an enigmatic, relatively young mountain belt with sharp relief (up to 4,500 m high) that developed thousands of kilometers away from the nearest current plate margins. The Fuyun area, at the interface between the southern margin of the Chinese Altai and the Junggar Basin, represents a key locality for understanding the Meso‐Cenozoic de...

NW Iran, situated between the Arabian and Eurasian plates, carries a record of both Paleo-Tethyan and Neo-Tethyan tectonic evolution. During the Wilson Cycle of Tethys Ocean opening and closing, several episodes of magmatism from Late Paleozoic to latest Cenozoic generated a massive volume of intrusive rocks. These intrusives, which record cooling...

The accretionary orogenesis of the Central Asian orogenic belt is essential for understanding the reconstruction and growth of the Asian continent. The origin and accretion of the Bainaimiao arc along the northern margin of North China remain controversial. Here, a comprehensive study of field geology, geochemistry, and geochronology was performed...
Article
The Paleo-Asian Ocean, as the processor of the Altaids, was a long-lived ocean, and its subduction gave rise to substantial continental growth in the Central Asian continent. However, the location of the major oceanic basin and its evolution history are debatable, impeding our better comprehension of the early accretionary tectonics of the Paleo-As...
