Early Paleozoic to Devonian multiple-accretionary model for the Qilian Shan, NW China
TL;DR: The Qilian Shan has an excellent record of early to middle Paleozoic subduction-accretion that resulted from convergence between the Alax and Qaidam blocks, but there is no consensus about its detailed tectonic history as discussed by the authors.
Journal ArticleDOI
Hualong Complex, South Qilian terrane: U–Pb and Lu–Hf constraints on Neoproterozoic micro-continental fragments accreted to the northern Proto-Tethyan margin
TL;DR: A geochronology of morphologically complex zircons sheds light on the history of the Neoproterozoic Hualong Complex as mentioned in this paper, which contains mafic to felsic magmatic rocks, cherts and turbiditic sediments, some of which have been metamorphosed to amphibolite grade.
Journal ArticleDOI
Geochemical Constraints on the Provenance and Depositional Setting of the Devonian Liuling Group, East Qinling Mountains, Central China: Implications for the Tectonic Evolution of the Qinling Orogenic Belt
TL;DR: In this article, geochemistry is used to constrain the provenance and depositional setting of the Middle-Upper Devonian Liuling Group clastic sedimentary rocks from the East Qinling Mountains.
Journal ArticleDOI
Silurian clastic sediments in the North Qilian Shan, \{NW\} China: Chemical and isotopic constraints on their forearc provenance with implications for the Paleozoic evolution of the Tibetan Plateau
TL;DR: In this article, a petrological analysis suggests that the clast composition of fan conglomerates is complex and that abundant lenticular conglomerate beds contain mainly subrounded-rounded metamorphic clasts; whereas the Tongziba and Haichaoba sections contain volcanic, chert, limestone, ultramafic and granitoid clasts.
Journal ArticleDOI
Middle Triassic arc magmatism along the northeastern margin of the Tibet: U–Pb and Lu–Hf zircon characterization of the Gangcha complex in the West Qinling terrane, central China
TL;DR: The Gangcha complex is typical of Mesozoic magmatic complexes in the northeastern margin of the Tibet plateau and hence gives rise to uncertainty concerning the tectonic evolution of the northeastern Tibet Plateau and the timing of the closure of the Palaeo-Tethys ocean.
