| description | The eastern Junggar has experienced multistage intra-continental deformations since the late Paleozoic. The checkerboard structure is one of the most notable features of the Junggar Basin, especially the eastern Junggar Basin, and its formation and evolution is a microcosm of the intracontinental deformation within the Central Asian Orogenic Belt. However, it needs to be clarified how and when the checkerboard structure developed within the Junggar Basin. In this study, we focused on Permian-Cenozoic deformations around the Junggar Basin. We proposed that the deformation was mainly driven by plate margin interaction, especially by the Tethys tectonic domain. During the Late Permian, the Junggar Basin experienced the nearly EW-trending compression, which resulted in the overall deformation of the basin and the formation of a series of nearly N-S-trending thrust faults and related folds, laying the foundation for the chessboard structure of the eastern Junggar Basin and even the entire basin. The Junggar Basin and its surrounding basins experienced regional extension during the Early-Middle Jurassic. An important sinistral transtension event occurred in the northeastern and northwestern margins of the basin, forming the large-scale strike-slip duplexes. During the Late Jurassic, the eastern Junggar Basin experienced nearly E-W shortening, which resulted in the nearly N-S-trending folding of the pre-Jurassic strata and further strengthened the original N-S-trending folds and faults. The driving force for the Late Jurassic deformation may result from the Tethys tectonic domain to the south, which also caused a clockwise rotation of the Junggar Basin. During the Late Cretaceous, the eastern Junggar Basin experienced nearly N-S-trending shortening, which led to the deformation of the previous N-S-trending folds and faults and the finalization of the checkerboard structural style. During the late Cenozoic, the eastern Junggar Basin was affected by the far-field effect of the India-Eurasian collision, but the intensity and sphere were relatively weak. |
