Abstract The Oulongbuluke Block, which is located in the northeastern margin of the Tibet Plateau, has traditionally been considered to be a fragment of the Tarim Craton. Here we present a systematic petrologic, geochemical, and zircon U-Pb and Hf isotopic investigation on mafic granulite and migmatite in the Oulongbuluke Block. The mafic granulite is mainly composed of clinopyroxene, orthopyroxene, plagioclase, amphibole and quartz, with peak metamorphic P-T contions of 6.5–8.8 kbar, 745–770 °C...

Abstract The East Kunlun Orogen (EKO) is characterized by widely distributed granitoids with different ages, which are keys to understanding the tectonic evolution of the Central China Orogenic Belt. Zircon U–Pb ages and Hf isotopic compositions, as well as the whole rock geochemistry of the gneissic granite from the basement rock, are carried out to elucidate the Meso– to Neoproterozoic tectonics of the EKO. The Al–rich minerals, including muscovite and tourmaline, and the A/CNK ratios (1.07–1....

Abstract This paper presents the results of U–Pb dating of detrital zircons from six metasedimentary rocks in the Taowan and Kuanping groups in the northern margin of the North Qinling Orogenic Belt (NQB), Central China, for constraining the tectonic affinity of the NQB, the existence time and tectonic features of the Kuanping Ocean and the accurate northern boundary of the NQB. Zircon U–Pb dating indicates that the protoliths of the two metasedimentary rocks from the upper and lower parts of th...

Abstract The widely distributed high-grade gneisses in the East Kunlun Orogenic Belt (EKOB) are keys to understand the Precambrian tectonic evolution of the Northern Tibetan Plateau. In this study, new LA-ICP-MS zircon U–Pb ages from paragneiss and schist of the Proterozoic Jinshuikou Group and quartzite of the Proterozoic Binggou Group are reported in an attempt to evaluate the Neoproterozoic and Paleozoic tectono-thermal events of the EKOB. These geochronologic data can be classified into 4 gr...

Abstract The North Qinling terrane (NQT) is considered to be a relic of the Grenvillian orogeny and is related to the formation of Rodinia because of the extensive magmatism and typical amphibolite-facies metamorphism that occurred in the NQT at ∼1.0 Ga. It was also involved in the Qinling orogen in the early Paleozoic during the amalgamation of Gondwana, as indicated by a phase of ultra-high pressure metamorphism at ∼500 Ma. We provide a synthesis of the tectono-magmatism, metamorphism, detrita...

Abstract The North Qinling Terrane, including the Kuanping, Erlangping and Qinling groups, is located in the northern part of the Qinling Orogen. Here we present results from structural analyses of the North Qinling Terrane and its surrounding regions. Three episodes of deformation (D 1 , D 2 and D 3 ) are recognized. The D 1 deformation is characterized by NNE-dipping and SSW-dipping penetrative foliations (S 1 ). The S 1 foliations are mainly marked by a strong preferred orientation of hornble...

Abstract Appinite is commonly derived from a mantle source in subduction zones and thus holds a key to constrain the tectonic evolution of ancient orogens. This study presents chronological, mineralogical and geochemical data for one appinitic pluton from the south Tethyan suture zone in the East Kunlun orogen, Northern Tibetan Plateau. The pluton is predominantly composed of hornblende-rich mafic appinites, with minor amounts of granodiorite. Zircon U–Pb age of the granodiorite (466 Ma) is iden...

Abstract The high Pb isotopic ratios among the North Qinling Microcontinent (NQM), the western margin of the Yangtze Craton (WYC) and the western part of South Qinling (WSQ) indicate an identical or very similar origin of their basement. In addition, the analogical peak values of Paleoproterozoic detrital zircons also agree that the NQM originated from the WYC. The evolution of the NQM and the Kuanping Ocean is closely related to the aggregation and break-up of the Columbia supercontinent. Accor...

Abstract Neoproterozoic granitic rocks in the Dakendaban Group are widely distributed throughout the Xitieshan area as the old basement in North Qaidam, NW China. The granitic rocks are composed predominantly of K-feldspar, plagioclase, quartz, muscovite and biotite, with subordinate zircon, garnet, titanite and sillimanite. Two granitic rock samples yielded ages of 930 ± 6 Ma and 918 ± 6 Ma using LA-ICPMS zircon U–Pb dating, which are interpreted as the protolith formation age of the granitic r...

Abstract Phanerozoic high-Mg diorites and granodiorites are known to be related to diverse subduction styles at convergent margin settings but have not been linked to collision processes. The Santonggou complex in the eastern Kunlun Orogen is composed of a dominant granodiorite intruded by small stocks and dykes of porphyritic granodiorites and diorites, which are all characterized by high MgO and Ni but low Yb and Y contents. Mafic microgranular enclaves (MMEs) occur in the granodiorite and the...

Abstract Our understanding of the early evolution of the Yangtze Block is limited by the sparsely dispersed nature of pre-Neoproterozoic exposures. New, integrated petrographic, zircon U-Pb age and Hf-Nd isotope analyses, and whole-rock geochemical data for early Paleoproterozoic granites in the Phan Si Pan Complex provides new insights into the evolution of the Yangtze Block as well as its role in the Pre-Nuna supercontinent. LA-ICP-MS zircon U-Pb dating of magmatic zircons from quartz monzonit...

Abstract The cause of across-arc geochemical and isotopic variations above subduction zone is still controversial. The researches on petrogenesis of arc-type mafic intrusive rocks may give important insights into the cause of the variations. Here we undertakes an integrated study of U–Pb zircon dating, geochemical and Sr–Nd–Hf isotopic compositions for the rear-arc (Keqianyakou and Jinyuan plutons) and arc-front mafic intrusive rocks (Liushendong and Yishenchun plutons) in the southern Central Q...
