The northern margin of Bogda Mountain is the key part between Junggar Basin and Tianshan Orogenic Belt, and is the key area to study the relationship between basin and mountain. The relationship between the tectonic evolution and sedimentary temporal and spatial evolution of the Middle and Late Permian in the northern margin of Bogda Mountain is controversial.Methods: By means of field survey, microscopic rock thin section identification, particle size analysis experiment and seismic data analysis, two sections of the eastern and western Bogda Mountain north margin, Dalongkou section and Jingjingzigou section, were studied to analyze their sedimentary types and evolution process, analyze the tectonic deformation and development characteristics of the basin—mountain, and explore the sedimentary response of tectonic movement.Results:The results show that the Wulabo Formation of Guadalupian is lake-delta facies, the Jingjingzigou Formation to Hongyanchi Formation is lacustrine facies, the Quanzijie Formation of Lopingian is alluvial fan-fluvial facies, and the Wutonggou Formation and Guodikeng Formations are Shoal shallow lake-delta facies. The study area can be divided into two main structural layers, the lower structural layer with extensional fault depression as the main structure, and the upper structural layer with foreland thrust as the main structural deformationConclusions: Multi-stage tectonic activities controlled the sedimentary evolution of Guadalupian and Lopingian. Under the compressional tectonic background, the lacustrine facies of Guadalupian transformed into Lopingian alluvial fan-fluvial facies, and the tectonic activities tended to be stable in the late period, and the region entered the peneplanization stage.
