Paleozoic tectonics of the southern Chinese Tianshan: Insights from structural, chronological and geochemical studies of the Heiyingshan ophiolitic mélange (NW China)

Wang, Bo; Shu, Liangshu S.; Faure, Michel; Jahn, Bor-Ming; Cluzel, Dominique; Charvet, Jacques; Chung, Sun-Lin; Meffre, Sébastien

In the southern Chinese Tianshan, the southernmost part of the Central Asian Orogenic Belt (CAOB), widespread ophiolitic mélanges form distinct tectonic units that are crucial for understanding the formation of the CAOB. However, the timing of tectonic events and subduction polarity are still in con...

New 40Ar/39Ar age constraints on the Late Palaeozoic tectonic evolution of the western Tianshan (Xinjiang, northwestern China), with emphasis on Permian fluid ingress

de Jong, K; Wang, B; Faure, M; Shu, L; Cluzel, D; Charvet, J; Ruffet, G; Chen, Y

Laser-probe dating of mylonite whole-rock samples from the North Tianshan - Main Tianshan fault zone that cross-cuts the North Tianshan domain's southern margin yielded 40Ar/39Ar spectra with 255-285 Ma ages. Biotite from an undeformed, Early Carboniferous granite, which cuts the steep mylonitic fol...

New 40Ar/39Ar age constraints on the Late Palaeozoic tectonic evolution of the western Tianshan (Xinjiang, northwestern China), with emphasis on Permian fluid ingress

De Jong, Koenraad; Wang, Bo; Faure, Michel; Shu, Liangshu S.; Cluzel, Dominique; Charvet, Jacques; Ruffet, Gilles

Laser-probe dating of mylonite whole-rock samples from the North Tianshan—Main Tianshan fault zone that cross-cuts the North Tianshan domain's southern margin yielded 40Ar/39Ar spectra with 255–285 Ma ages.

Evolution of calc-alkaline to alkaline magmatism through Carboniferous convergence to Permian transcurrent tectonics, western Chinese Tianshan

Wang, B; Cluzel, D; Shu, L; Faure, M; Charvet, J; Chen, Y; Meffre, S; de Jong, K

Continuous magmatic activity occurred in the western Chinese Tianshan, Central Asia, from the Carboniferous to the Permian, i.e. before and after the Late Carboniferous amalgamation of Junggar and the Yili Blocks. Zircon U-Pb LA-ICPMS and Ar-Ar data reveal a coincidence in time between regional wren...

Continuous magmatic activity occurred in the western Chinese Tianshan, Central Asia, from the Carboniferous to the Permian, i.e. before and after the Late Carboniferous amalgamation of Junggar and the Yili Blocks. Zircon U–Pb LA-ICPMS and Ar–Ar data reveal a coincidence in time between regional wren...
