LA-ICP-MS zircon dating, geochemistry, petrogenesis and tectonic implications of the Dapingliang Neoproterozoic granites at Kuluketage block, NW China

Origin of two types of rhyolites in the Tarim Large Igneous Province: Consequences of incubation and melting of a mantle plume

“…This petrogenetic model is further supported by a plot of Th/La against Nb/La (Fig. 5d), in which most of the low Nb-Ta rhyolites plot within the field of the Tarim basement/continental crust (Cao et al, 2011;Chen et al, 2000;Hu et al, 2000;Jiang et al, 2005;Rudnick and Gao, 2003;Zhang et al, 2007bZhang et al, , 2009Zhang et al, , 2012. Nevertheless, it should be pointed out that other low Nb-Ta rhyolites define a geochemical trend towards the middle-upper crust (Fig.…”

“…Less is known about Mesoproterozoic-Neoproterozoic history of the Tarim craton. However, recently discovered Proterozoic-age zircon grains both in metasedimentary and igneous rocks may indicate the existence of extensive Mesoproterozoic-Neoproterozoic basement in the Tarim craton (Cao et al, 2011;Ge et al, 2012;Long et al, 2011;Ma et al, 2012;Wang et al, 2009;Wu et al, 2009;Zhang et al, 2007a).…”

New geochemical and combined zircon U–Pb and Lu–Hf isotopic data of orthogneisses in the northern Altyn Tagh, northern margin of the Tibetan plateau: Implication for Archean evolution of the Dunhuang Block and crust formation in NW China

“…Because of an extensive cover of desert recent deposits, Precambrian basement rocks are only exposed on the craton margins around the Tarim basin, e.g. the Kuluketage (also named as "Quruqtagh" in the literature) Block in the northeast, the Aksu Block in the northwest, the Tiekelike Block in the southwest and the Dunhuang Block in the east (BGMRX, 1993;Cao et al, 2011;Ge et al, 2012;Guo et al, 2003Guo et al, , 2005He et al, 2012;Hu and Wei, 2006;Hu et al, 2000;Long et al, 2010Long et al, , 2011aLong et al, , 2011bLong et al, , 2012Lu and Yuan, 2003;Lu et al, 2008b;Shu et al, 2011;Xu et al, 2005;Zhang et al, 2007bZhang et al, , 2009Zhang et al, , 2011Zhang et al, , 2012dZhang et al, , 2013aZhu et al, 2011aZhu et al, , 2011b. Among the Precambrian basement, Archean rocks predominantly consist of strongly deformed tonalitic-trondhjemiticgranodioritic orthogneisses (TTG) and metamorphosed supracrustal xenoliths, sparsely exposed along the northern and eastern margins (Zhao and Cawood, 2012 and references therein).…”

Precambrian tectonic evolution of Central Tianshan, NW China: Constraints from U–Pb dating and in situ Hf isotopic analysis of detrital zircons

“…Paleoproterozoic and Neoarchean schist, gneiss and TTG suite (tonalite, trondhjemite and granodiorite) are scattered in the Altyn Tagh and Tieklik areas ( [Zhang et al, 2007b] and [Lu et al, 2008a] ), and in the Kuruqtagh area , [Shu et al, 2011] , [Long et al, 2010] , [Long et al, 2011a] , [Cao et al, 2011] and [Zhu et al, 2011a] ) (Fig. 2).…”
