Journal ArticleDOI
TL;DR: In this article, the authors argue that the production of mantle-derived or juvenile continental crust during the accretionary history of the Central Asian Orogenic Belt (CAOB) has been grossly overestimated.

Journal ArticleDOI
TL;DR: An overview of the orogenic components and their amalgamation in the western Central Asian Orogenic Belt (CAOB) is presented in this paper, which records the convergence and interactions among various types of orogens including the Japan-type, Mariana-type and Alaska-Aleutian-type arc systems, as well as the active marginal sequences of the Siberia Craton, which incorporated wide accretionary complexes and accreted arcs and terranes.

541 citations


Journal ArticleDOI
TL;DR: In this article, the authors trace the development of ideas concerning long-term episodic orogeny and continental crust formation, such as those embodied in the chelogenic cycle, through the first realization that such episodicity was the manifestation of the cyclic assembly and breakup of supercontinents, to the surge in interest in supercontinent reconstructions.

Journal ArticleDOI

Journal ArticleDOI
TL;DR: The oldest gold deposits in Asia reflect accretionary events along the margins of the Siberia, Kazakhstan, North China, Tarim-Karakum, South China, and Indochina Precambrian blocks while they were isolated within the Paleotethys and surrounding Panthalassa Oceans as discussed by the authors.

Journal ArticleDOI
TL;DR: In this paper, a comprehensive synthesis of the nature of occurrence, geochemical characteristics and geochronological features of the oceanic island basalts (OIB) and ophiolite units in the accretionary complexes of Central and East Asia (Russia, Kazakhstan, Kyrgyzstan, Tajikistan, Mongolia, and China) and the Western Pacific (China, Japan, Russia) preserve valuable records of ocean plate stratigraphy (OPS).

Journal ArticleDOI
TL;DR: In this paper, detrital zircons from samples of Palaeozoic to Mesozoic sedimentary rocks have been collected in Malaysia, Thailand, Laos, Vietnam, Cambodia and China, dated by the LA ICPMS, U-Pb technique and assigned to tectonic terrans or regions within terranes.

Journal ArticleDOI
TL;DR: In contrast to modern-day plate tectonics, studying Precambrian geodynamics presents a unique challenge as currently there is no agreement upon paradigm concerning the global geodynamics and lithosphere tectonic for the early Earth.

253 citations


Journal ArticleDOI
TL;DR: The high-grade terranes of southern India are made up of four main tectonic units; from north to south these are a) the Salem Block, b) the Madurai Block, c) the Trivandrum Block, and d) the Nagercoil Block as discussed by the authors.

Journal ArticleDOI
TL;DR: In this article, the authors present a new tectonic and metallogenic model for Phanerozoic mainland SE Asia and conclude that incipient arc/backarc basin magmatism is the key to the formation of many important ore deposits in the Truong Son and Loei fold belts.

Journal ArticleDOI
TL;DR: The effects of the end-Permian mass extinction on continental habitats and on terrestrial life have been extensively studied by geologists and palaeontologists as mentioned in this paper, with the effects on land were substantial, with massive erosion following the stripping of vegetation associated with long-term aridification and short-term bursts of warming and acid rain.

Journal ArticleDOI
TL;DR: In this paper, the authors proposed a new model in which chromitite formation was involved in intra-oceanic subduction zones initiated in closing oceanic basins, where the upward flow changes from vertical to subhorizontal and velocity is greatly reduced.

Journal ArticleDOI
TL;DR: In this paper, a series of experiments were run using a 2-D petrological-thermomechanical numerical model in which the collision of spontaneously moving continental plates was simulated for values of ambient upper-mantle temperature and radiogenic heat production increasing from those appropriate to the present-day.

Journal ArticleDOI
TL;DR: The end Ordovician (Hirnantian) extinction was the first of the five big Phanerozoic extinction events, and the first that involved metazoan-based communities as mentioned in this paper.

Journal ArticleDOI
TL;DR: The Lhasa terrane in southern Tibet is composed of Precambrian crystalline basement, Paleozoic to Mesozoic sedimentary strata and Paleozoics to Cenozoic magmatic rocks as mentioned in this paper, which is the key for revealing the origin and evolutionary history of the Himalayan-Tibetan orogen.

Journal ArticleDOI
TL;DR: In this article, the authors review the passive margins of the Atlantic and Indian oceans with the aim to evaluate the extent in which oceanic openings used former sutures and analyse the potential role of mantle plumes in continental break-up.

Journal ArticleDOI
TL;DR: In this article, detrital zircon U-Pb age and Hf isotope datasets are used to delineate the early history of the Cathaysia Block, which is one of the largest Precambrian blocks in eastern Asia.

Journal ArticleDOI
TL;DR: In this article, the exact location of the suture between the Simao and Yangtze blocks has been investigated, and it was shown that the detrital and inherited-xenocrystic zircons from Paleozoic sedimentary rocks and a Triassic granite dyke in the Laowangzhai-Mojiang suspect terrane belong to the same suture.

Journal ArticleDOI
TL;DR: In this article, the authors characterized the timing and tectonics of the major Mesozoic magmatism and the associated gold metallogeny in this region through a comprehensive U-Pb geochronological and Hf isotope investigation of zircons in a suite of granitoids, mafic magmatic enclaves, melanocratic dikes and melted basement rocks.
