“…2.00 and 1.95 Ga (Yin et al, 2011;Dan et al, 2012). As previously noted, the requirements for such rapid sedimentary recycling are only met in a few distinctive tectonic settings that involve processes such as lithospheric delamination, back-arc basin opening, mantle plume ascent or continental rifting Kemp et al, 2007;Zheng et al, 2008;Collins and Richards, 2008;Foster and Goscombe, 2013). A common feature of these tectonic settings is the presence of asthenosphere upwelling, consistent with the generation of high-temperature Stype granites (Sylvester, 1998).…”

“…The time interval between the deposition of sedimentary rocks and formation of magmatic rocks can be less than 50 m.y. (e.g., Kemp et al, 2007;Zheng et al, 2008). Several mechanisms have been proposed to explain the rapid formation of S-type granites.…”

“…The rapid formation of Stype granites in collisional orogenic belts, however, has commonly been attributed to mantle plumes (Jiangnan Orogen, South China Block, Li et al, 2003) or continental rifting (Jiangnan Orogen, Zheng et al, 2008). In some cases, coeval granulites and mafic magmatism accompanied sediment recycling, as in the Hidaka metamorphic belt, Japan (accretionary orogen, Kemp et al, 2007) and the Silurian Tongbai Orogen, Central China (collisional orogen, Wang et al, 2011a). Such examples of coeval mafic magmatism, felsic magmatism and granulite metamorphism provide multiple constraints on contemporary geodynamics, which can help to resolve the origin of S-type granites.…”

“…Several mechanisms have been proposed to explain the rapid formation of S-type granites. For subduction systems or accretionary orogens, the rapid formation of S-type granites and related rocks has been accounted for by models of back-arc basin opening (Cenozoic Hidaka metamorphic belt, Japan; Kemp et al, 2007) and lithospheric delamination (Ordovician Lachlan Fold Belt, Australia; Foster and Goscombe, 2013) or by models that combine both features (Collins and Richards, 2008). The rapid formation of Stype granites in collisional orogenic belts, however, has commonly been attributed to mantle plumes (Jiangnan Orogen, South China Block, Li et al, 2003) or continental rifting (Jiangnan Orogen, Zheng et al, 2008).…”

a b s t r a c t S-type granites, typically derived from the rapid recycling of sedimentary rocks, are sometimes accompanied by contemporary mafic magmatism and granulite metamorphism. However, the geodynamic context for such rock suites is often highly disputed, with various model proposed, including back-arc basin opening, lithospheric delamination, mantle plume and continental rifting. The Paleoproterozoic Khondalite Belt in the North China Craton provides an example of synchronous mafic and felsic magmatism that was accompanied by granulite-facies metamorphic events for which the tectonic affinities of these rocks remains unclear. This study integrates in situ zircon Hf-O isotope analyses, whole-rock geochemistry and Nd isotope results for the earliest two-mica granites (ca. 1.95 Ga) in order to provide constraints on the above issues. The granites are strongly peraluminous (A/CNK value >1.1), and characterized by high zircon ␦18 O values of 7.3-10.6‰, corresponding to calculated magmatic ␦ 18 O values of 9.1-12.3‰, similar to those of typical S-type granites. They have relatively high and homogeneous ε Nd (t) values of −1.1 to +0.9 and highly variable zircon ε Hf (t) values ranging from −1.0 to +8.3. In situ zircon Hf-O isotopic compositions indicate that the S-type granites may contain some mantle or juvenile crustal components in addition to a sediment component. Based on the new results and published data, a slab break-off model is proposed to explain the rapid recycling of sedimentary precursors and the generation of the ca. 1.95 Ga S-type granites.

“…The early Eocene granites (45-46 Ma) occur in the northern part of the Hidaka Belt. The zircon age of 37 Ma for a granite from Shirataki is similar to that of a tonalite and a granite from the Hidaka metamorphic belt (37.4 ± 0.3 Ma; Kemp et al, 2007). So, this late Eocene episode of granitoid emplacement is well established.…”

The mechanism of continental growth of the Altaids is currently under debate between models invoking continuous subduction-accretion or punctuated accretion by closure of multiple ocean basins. We use the Yueyashan-Xichangjing ophiolite belt of the Beishan Collage (southern Altaids) to constrain the earliest oceanic crust in the southern Paleoasian Ocean. Five lithotectonic units were identified from south to north: the Huaniushan block, a sedimentary passive margin, the structurally incoherent Yueyashan-Xichangjing ophiolite complex, a coherent sedimentary package, and the Mazongshan island arc with granitic rocks. We present a structural analysis of the accretionary complex, which is composed of the incoherent ophiolitic melange and coherent sedimentary rocks, to work out the tectonic polarity. A new weighted mean 206 Pb/ 238 U age of 534.4 ± 3.4 Ma from a plagiogranite in the Yueyashan-Xichangjing ophiolite indicates that the ocean floor formed in the early Cambrian. Furthermore, we present new geochemical data to constrain the tectonic setting of the YueyashanXichangjing ophiolite, and obtained seven U-Pb ages of Sandstone and granitoid and five Ar/Ar ages. The Yueyashan-Xichangjing ophiolite was emplaced as a result of northward subduction of an oceanic plate beneath the Mazongshan island arc to the north at about 420 Ma. Together with data from the literature, our work demonstrates that there were multiple overlapping periods of accretion existed in the Palaeozoic in the northern and southern Altaids. Therefore, a model of multiple accretion by closure of several ocean basins is most viable. Key words:Beishan, Yueyashan-Xichangjing, ophiolite, Accretionary complex, Altaids. The Central Asian Orogenic Belt (CAOB) is characterized by amalgamation of various island arcs, ophiolites, accretionary prisms, oceanic plateaus and possibly some micro-continents, during the progressive subduction-accretion processes. Isotopic data suggest significant Phanerozoic crustal growth in the CAOB, whereas recycling of ancient crust is also addressed by some recent researchers. The Russian Altai is one of the key components of the CAOB, consisting of part of the Altai-Mongolian terrane (AM) in Russia, the Gorny Altai terrane (GA) and the Charysh-Terekta-Ulagan-Sayan suture (CTUSs) zone. Voluminous granitoids and their volcanic equivalents, as well as a series of Paleozoic sedimentary and meta-sedimentary rocks occur, but they have not been well investigated. Age and source nature of these rocks can provide critical constraints on the crustal growth, sedimentary basin evolution, and tectono-thermal events in Russian Altai area.In this study, two volcanic rocks and a biotite-gneiss along the CTUSs zone were collected for zircon U-Pb and Hf-isotope analysis. Zircons from the two volcanic rocks yield consistent crystallization ages of 420.9±1.4 Ma and 421.4±2.5 Ma, respectively, indicating a magmatic activity in the latest Silurian. These zircons are characterized by low initial 176 Hf/ 177 Hf isotopic ratios, with ε Hf (...

Paleozoic accretionary orogenesis in the Paleo-Asian Ocean: Insights from detrital zircons from Silurian to Carboniferous strata at the northwestern margin of the Tarim Craton

et al. 2015

A detrital zircon U-Pb and Lu-Hf isotopic study was carried out in the Middle Silurian to Late Carboniferous sedimentary strata of the northwestern Tarim Craton in order to understand accretionary processes in the southern part of the Central Asian Orogenic Belt. Detrital zircons from these strata yielded U-Pb ages clustering around 2.8-2.3 Ga, 2.0-1.7 Ga, 1.3-0.9 Ga, 880-600 Ma, and 500-400 Ma, with age populations and Hf isotopic signatures matching those of magmatic rocks in the Tarim Craton and the Central Tianshan Block. Abundant 500-400 Ma detrital zircons most likely reflect deposition in a retroarc foreland basin inboard of an Andean-type magmatic arc to the north, supporting the northern Tarim-Central Tianshan connection during early Paleozoic time. The absence of 380-310 Ma zircon population in the Carboniferous siliciclastic rocks suggests that the Central Tianshan Block may have been separated from the Tarim Craton in the Early Devonian, caused by the interarc/back-arc opening of the South Tianshan Ocean. We propose an accretionary orogenic model switching from advancing to retreating mode during Paleozoic time in the southwestern part of the Paleo-Asian Ocean. This transition most likely occurred coevally with the rifting of Southeast Asian blocks from the northeastern margin of Gondwana.
