Abstract How ophiolitic melanges can be defined as sutures is controversial with regard to accretionary orogenesis and continental growth. The Chinese Altay, East Junggar, Tianshan, Beishan belts of the southern Central Asian Orogenic Belt (CAOB) in Northwest China, offer a special natural laboratory resolve this puzzle. In Erqis unit consists coherent assemblages, forming Paleozoic complex. At least two (Armantai, Kelameili) characterized by imbricated melanges, Nb-enriched basalts,...
Abstract The mechanism of continental growth the Altaids is currently under debate between models invoking continuous subduction-accretion or punctuated accretion by closure multiple ocean basins. We use Yueyashan–Xichangjing ophiolite belt Beishan collage (southern Altaids) to constrain earliest oceanic crust in southern Palaeo-Asian Ocean. Five lithotectonic units were identified from S N: Huaniushan block, a sedimentary passive margin, structurally incoherent complex, coherent package and...
Abstract The Changning–Menglian orogenic belt ( CMOB ) in the southeastern Tibetan Plateau, is considered as main suture zone marking closure of Palaeo‐Tethys Ocean between Indochina and Sibumasu blocks. Here, we investigate recently discovered retrograded eclogites from this terms their petrological, geochemical geochronological features, with aim constraining metamorphic evolution protolith signature. Two types metabasites are identified: mafic schists. igneous precursors exhibit rare...
AbstractThe tectonic nature of metamorphic terranes and their role in orogenesis are problematic. Here we present new U–Pb ages geochemical data for widespread rocks associated granitoids from Northwest China. Orthogneisses the complexes have crystallization ∼457, ∼452, ∼526 Ma. One paragneiss (schist) has a maximum depositional age 312 ± 7 Three foliated granites were emplaced at ∼450, ∼349, ∼410 Ma, all lack inherited Precambrian ages. The may undergone multiple petrotectonic events as...
The Eastern Block of the North China Craton records Paleoproterozoic oceanic plate subduction, opening and subsequent closure a back-arc basin, following collisional orogenic event to generate Jiao-Liao-Ji Belt (JLJB). However, processes involved in initiation subduction remain unclear. This study presents U–Pb age trace elemental data for detrital zircons from Langzishan Formation, lowermost sedimentary unit within JLJB, constrain provenance, depositional age, environment this formation as...
Abstract An Al‐rich, quartz‐absent corundum‐bearing pelitic granulite is reported for the first time at Diebusige complex in Alxa Block western part of Khondalite Belt (KB), North China Craton (NCC). A detailed petrographic study shows that a quartz‐present domain occurs porphyroblastic garnet cores from granulite, with prograde metamorphic mineral assemblage (M 1 ) + plagioclase quartz biotite spinel rutile ± melt, and matrix this rock, preserved peak 2 corundum K‐feldspar melt retrograde 3...
The Hongyanjing inter-arc basin, is located at the central part of Beishan Orogenic College (BOC), Gansu Province, northwest China. Thick sequences Permian sediments were strongly folded, forming extremely spectacular superposed folds. To better understand thermal history basin and to potentially constrain timing deformation, apatite fission track thermochronology method was applied on two folds in Basin. Samples from yield AFT ages ranging ∼206 118 Ma. peak largely consistent between...
Permian progressive accretion or continental rift is a long‐term debate topic in the final evolution of Altaïds Central Asian Orogenic Belt (CAOB). The Beishan orogenic collage southernmost part CAOB recorded ultimate closure Palaeo‐Asian Ocean. In this paper, we present (a) field structural measurements/data observations and fold geological maps Liuyuan Basin, (b) geochronological results to rocks on Shibanshan arc (c) regional data collected around area, order investigate tectonic setting...
