Abstract Late Triassic granitoids containing abundant mafic microgranular enclaves (MMEs) occur widely in the Eastern Kunlun Orogenic Belt (EKOB). In this work, we present mineral chemistry, zircon U-Pb ages and Lu-Hf isotopes, whole-rock chemistry and Sr-Nd isotope compositions of the MMEs and host granodiorite from the Huda pluton in the Elashan area within the easternmost domain of the EKOB. These rocks contain inherited (Meso- to Neoproterozoic) and xenocrystic (ca. 240 Ma) zircon grains tha...

Abstract Deep lithospheric processes associated with the formation of major orogens, including the removal of lower crust and underlying mantle through delamination associated with orogen building are poorly constrained. With a view to evaluate the potential link between deep geodynamic processes and magmatic events, we performed in situ zircon Hf-O-Li isotopic analyses of granitoids from the Eastern and Western Junggar, Altai and Beishan orogens, within the Central Asian Orogenic Belt (CAOB). T...

Abstract The Western Dharwar Craton (WDC) and the Karwar Block (KB) in southern Peninsular India provide important windows to Earth’s early crustal evolution and continental growth as these domains likely represent fragments of the first landmass or supercontinent on our planet. Here we employ, for the first time, a coupled laser ablation zircon U-Pb dating and in-situ Rb-Sr dating of micas (biotite, muscovite) and feldspars to evaluate the Meso- to Neoarchean crustal evolution and Proterozoic m...

Abstract The North China Craton (NCC) offers a window to Archean–Paleoproterozoic crustal evolution. Following the amalgamation of microblocks during Neoarchean, the NCC witnessed another protracted Wilson cycle in the Paleoproterozoic with subduction-accretion-collision process. Here we report a newly identified suprasubduction zone ophiolite suite from the Miyun complex in the NCC where a rare and near-complete ophiolite succession is preserved including serpentinite, lherzolite, olivine clino...

Abstract Subduction erosion along active convergent plate margins involves arc subduction, tectonic erosion and sediment subduction. Here we investigate the metasedimentary rocks enclosing blueschists and eclogites in the Changning–Menglian orogenic belt (CMOB) of the southeastern Tibetan Plateau which marks the main suture associated with the closure of the Paleo-Tethyan Ocean between the Baoshan–Tengchong and Lanping–Simao blocks. We present an integrated study of petrology, mineral chemistry,...

Abstract The eastern China region underwent an intense lithosphere thinning event during Mesozoic but the mechanism for this process remains controversial. Here we investigate the Early Cretaceous Guandian intrusive complex in southern segment of the Tancheng-Lujiang (Tan-Lu) fault zone, central-eastern China, to gain insights into lithospheric extension and thinning. We present zircon U Pb ages and Lu Hf isotope data, together with whole rock major and trace elements, and Sr Nd isotopes. The ma...

Abstract The Yongxin gold deposit is one of the prominent gold deposits in the Duobaoshan gold-copper metallogenic belt within the eastern domain of the Central Asian Orogenic Belt. The deposit has recently been discovered therefore, its genesis and economic significance remain unknown. Here, we present the results of pyrite thermoelectricity, fluid inclusion and H-O-Rb-Sr isotopic studies of different minerals with a view to decipher ore genesis and ore prospecting in the Yongxin gold deposit. ...

The East Kunlun Orogen is an important part of the East Tethys region and has received significant attention with regards to the evolution of the Tethys Ocean. This contribution presents geochronological,whole-rockmajor and trace element geochemical, and Sr-Nd-Hf isotopic data of magmatic rocks within the Kengdenongshe polymetallic deposit in the eastern part of the East Kunlun Orogen. Here, we report zircon U\\Pb ages of ca. 257 Ma and ca. 211 Ma for granite porphyry intrusions, and ca. 240Ma f...

The Jiaoxi deposit is the first Miocene quartz vein-type W deposit discovered in the western part of the Lhasa Terrane comprising with 39,000 metric tons of WO3. The mineralization occurs in wolframite-bearing hydrothermal tensional quartz veins and is associated with Miocene granites. The mineralization event can be divided into an early quartz-oxide stage succeeded by a sulfide stage, and a final fluorite-carbonate stage. Magmatic intrusions at the deposit include biotite monzogranite porphyry...
