Our understanding of the assembly history Asia depends critically on tectonic relationships between its major cratons, including Siberia, North China, South and Tarim. The intervening microcontinents these cratons can provide insight into paleogeographic paleotectonic but there is currently a general lack knowledge regarding basement geology microcontinents. Here we present results from systematic geologic mapping, U-Pb zircon dating, whole-rock geochemical analysis, synthesis existing data...

Abstract The involvement and location of the Neoarchean‐Paleoproterozoic North China craton in supercontinent Columbia remains enigmatic, tectonic history along its margins impacts our understanding connections between other continents. Here we present structural observations from a Paleoproterozoic mélange that is located northern margin refer to as Bayan Obo mélange. It composed structurally complex mixture metapelites metasedimentary rocks mixed with exotic blocks ultramafic‐mafic rocks,...

Abstract The present-day Tibetan plateau, which is the largest highland on Earth, formed primarily due to India-Asia collision since 50–60 Ma. development of plateau has been associated with Cenozoic two large intra-plateau sedimentary basins in north-central Tibet: Qaidam and Hoh Xil north south Eastern Kunlun Range, respectively. We conducted an integrated study these Range that separates them understand timing mechanisms their order decipher growth uplift history plateau. Crustal...

The sedimentary record in the Late Palaeoproterozoic‐Neoproterozoic Bayan Obo rift belt can provide critical insight into tectonic evolution of Columbia and North China Craton. In this study, we present new U–Pb geochronology, Hf isotopic analyses from Group, Mesoproterozoic kimberlite, gabbro to constrain depositional age potential provenance information Group. We show that Dulahala‐Jianshan, Bilute, Baiyinbaolage formations were deposited at ca. 1.81–1.7 Ga, 1.58–1.35 1.25–1.0...

Abstract The Tibetan Plateau, the largest highland on Earth, formed due to collision of India-Asia over past 50–60 m.y., and evolution Plateau impacts our knowledge continental tectonics. Examination northernmost margin is key unravelling deformation mechanisms acting in northern Tibet. left-slip Altyn Tagh fault system defines northwest separating Western Eastern Kunlun Ranges southwest. Both Cenozoic pre-Cenozoic crustal events at this junction between were responsible for construction...

The Yili porphyry-type molybdenum deposit is located in the Northeastern Inner Mongolia Autonomous Region China. Mineralization occurs mainly as veins, lenses, and layers within host porphyry. In order to better understand link between mineralization igneous rocks, we studied samples from underground workings. We report new Sensitive High Resolution Ion Microprobe II (SHRIMP II) zircon U–Pb Re–Os molybdenite ages geochemical data granitoids. Five yield a isochron weighted mean age of 131.1 ±...

Abstract The North China craton of central Asia is a natural laboratory for investigating early Earth tectonic processes including subduction and large-scale horizontal crustal motions. However, it remains unclear how when the formed from amalgamation several blocks orogens Archean Western Eastern blocks, late Central Orogenic Belt, Paleoproterozoic Northern Margin orogen. In this study, we integrated new existing geological field observations, zircon baddeleyite U-Pb geochronology,...

ABSTRACT The tectonic position of the North China Craton within Rodinia supercontinent remain unclear due to scarcity early Neoproterozoic magmatic rocks in region, resulting limited paleomagnetic data. In this study, we report discovery a metamorphic gabbro intrusion Bayan Obo Group, located northwestern rift zone at northern margin Craton. This finding offers crucial geological insights into addressing key scientific question. We utilised petrography, whole‐rock geochemistry, zircon U–Pb...

We conducted zircon U–Pb dating and geochemical analyses for the Qianjinchang (QJC) pluton in Xi Ujimqi, Northeast China, with an aim to determine their ages, petrogenesis, sources. The QJC consists of coarse/medium‐grained biotite monzogranite core fine‐grained granodiorite rim; those rocks intrude into quartz diorite but are intruded by minor intrusive phases, including small syenogranite, bodies, late diorite, granodiorite, granite, pegmatite dykes. Our new laser ablation inductively...

Abstract Zircon U–Pb dating and whole-rock geochemical analysis have been performed on Late Jurassic – Early Cretaceous intrusive rocks of the Ulanhot area, NE China, with aim constraining tectonic evolution central southern Da Xingan Range. indicates that magmatic events experienced four stages at: c. 155 Ma; 144 135–130 126 Ma. The Ma event consists quartz diorite granite-porphyryp characteristic high Sr Sr/Y or A/CNK (1.38), implying primary magma was derived from partial melting a...

The Xingmeng Orogenic Belt evolved through a long-lived orogeny involving multiple episodes of subduction and accretion. However, there is debate on its tectonic evolution during the Late Paleozoic. Here, we report geochemical, geochronological, isotopic data from strongly peraluminous granites gabbro-diorites Sunidzuoqi–Xilinhot region. Zircon U–Pb ages suggest that intrusive rocks were emplaced Early Carboniferous (333–322 Ma). exhibit geochemical characteristics similar to S-type...
