Provenance and ages of the Altyn Complex in Altyn Tagh: Implications for the early Neoproterozoic evolution of northwestern China

Initial rupture and displacement on the Altyn Tagh fault, northern Tibetan Plateau: Constraints based on residual Mesozoic to Cenozoic strata in the western Qaidam Basin

“…650 Ma (Gehrels et al, 2003a(Gehrels et al, , 2003bC. Wang et al, 2006;Zhang et al, 2011;Wang et al, 2013). Paleozoic intrusions within this range show zircon U-Pb ages ranging from ca.…”

“…With regard to the Eastern Kunlun Range, the Proterozoic basement rocks are isolated and show zircon U-Pb ages ranging from 1900 to 800 Ma (e.g., HGSI, 2003;Wang et al, 2013). The Paleozoic to late Proterozoic intrusions show a zircon U-Pb age peak around 430 Ma, which is based on early Paleozoic metamorphic rocks that represent the Ordovician-Silurian docking of the Kunlun and Tarim blocks (e.g., Matte et al, 1996;Cowgill et al, 2003;Li et al, 2013).…”

Ages and tectonic implications of Neoproterozoic ortho- and paragneisses in the Beishan Orogenic Belt, China

“…17a and b). Only a few 1048-906 Ma granitic gneisses with limited geochemical data were found in the Quruqtagh area in the northeast Tarim Craton and Altyn Tagh in the southeast, considered to be related to the assembly of the Rodinia supercontinent (Gehrels et al, 2003;Zhang et al, 2007bZhang et al, , 2010cShu et al, 2011;Wang et al, 2013). Their formation ages coincide with the 1014-845 Ma magmatic rocks in the BSOB and CTOB (this study; Chen et al, 2009;Hu et al, 2010;Peng et al, 2012;Huang et al, 2013;Jiang et al, 2013;Ye et al, 2013;He et al, 2014;Wang et al, 2014a,b) (Fig.…”

Age and nature of Cryogenian diamictites at Aksu, Northwest China: implications for Sturtian tectonics and climate

“…Moreover, the Tarim Block, which is a major continental block in China (along with the North and South China Blocks), has a basement that consists of a complete Neoproterozoic sedimentary succession. The magmatic records of the Tarim Block are similar to those of the South China Block (Guo et al 2005;Lu et al 2008;Shu et al 2011b), and several researchers have suggested that this basement was located on the periphery of the Rodinia supercontinent (Shu et al 2002Chen et al 2004;De Grave et al 2007;Zhang et al 2007aZhang et al , 2007bZhang et al , 2009aZhang et al , 2011Zhang et al , 2012bLi et al 2008;Xu et al 2009;Biske and Seltmann 2010;Glorie et al 2010;Metelkin et al 2010;Levashova et al 2011;Rojas-Agramonte et al 2011;Liu et al 2012;Ma et al 2012;Wang et al 2012aWang et al , 2013Zhao et al 2014).…”
