  The Junggar Basin is a Late Carboniferous foreland basin in northwestern China surrounded by different mountain belts. The west Junggar Basin has a complicated tectonic history with multiple subduction and collision events that controlled sedimentation and basin development. In this study, absolute dating of igneous rocks, rock geochemistry, and U-Pb detrital zircon geochronology were used to document the provenance of the Triassic-Jurassic clastic rocks in the northwest margin of Junggar Basin and determine local sources and tectonic setting. Granitic zircons with the youngest concordia age reveal the north Karamay pluton was formed at 292.6 ± 0.7 Ma, suggesting that they are postcollision granites. Late Triassic-Lower Early Jurassic strata were derived from Zhayier Mountain south of the Darbute fault. Starting with the Upper Early Jurassic Sangonghe Formation-Lower Middle Jur.. View More»
