Nonmarine time-stratigraphy in a rift setting: An example from the Mid-Permian lower Quanzijie low-order cycle Bogda Mountains, NW China

Tectonic Evolution of the West Bogeda: Evidences from Zircon U-Pb Geochronology and Geochemistry Proxies, NW China

“…In the Middle Permian, the depositional environment changed to terrestrial and lacustrine facies, resulting in a variable lithology of sandstone, siltstone, mudstone, and oil-bearing mudstone. The Upper Permian strata is composed of conglomerate and sandstone deposited in alluvial fan and braided river environment [28][29][30][31][32][33].…”

Petrogenesis and geodynamic implications of the Late Carboniferous felsic volcanics in the Bogda belt, Chinese Northern Tianshan

“…The Early Permian terrestrial charred wood of Prototaxoxylon was documented in the Wutonggou Formation (Wan et al, 2016). The change of paleogeographic environment mirrored the transition from marine to continental environment during Carboniferous-Permian (Carroll et al, 1990;Wartes et al, 2002;Obrist-Farner and Yang, 2015). Together with occurrence of thick red molasse along the south margin of the Bogda belt and the large-scale strike-slip shearing and rifting in the Early Permian (Shu et al, 2005), we suggest that an important tectonic transformation occurred between Carboniferous and Permian in the Bogda belt.…”
