“…The increasing relevance of structural-style-controlled petroleum traps to exploration in deeper basins has increased interest in deciphering how the structural style influences the basin formation and filling process (Harding & Lowell, 1979;Allen et al 1997;Polonia & Camerlenghi, 2002;Sepehr & Cosgrove, 2004;Hickman et al 2009). The structural style and generation reveal the deformation sequence accompanying transitions between tectonic regimes, which produces petroleum traps and causes the migration of petroleum into structural traps within sedimentary basins (Nieuwland et al 2001;Sherkatia & Letouzey, 2004;Zhou et al 2021). In several basins in China, both the pattern of subsidence with burial sedimentation and subsequent deformation were dominantly influenced by regional tectonics or the basement structural style (Yao et al 2004;Zhang et al 2014;Cheng et al 2016;Fan et al 2020;Xu & Gao, 2020).…”

The Eastern Depression in the Bayanhaote Basin in western Inner Mongolia has experienced multi-stage Meso-Cenozoic tectonic events and possesses considerable exploration potential. However, structural deformation patterns, sequences and the genesis of oil-bearing structures in the basin are still poorly understood. In this study, based on high-quality 2D seismic data and drilling and well-logging data, we elucidate the activities and structural styles of faults, the tectonic evolution and the distribution characteristics of styles, as well as assessing potential petroleum traps in the Eastern Depression. Five types of faults that were active at different stages of the Meso-Cenozoic faults have been recognized: long-lived normal faults active since the late Middle Jurassic; reverse faults and strike-slip faults active in the late Late Jurassic; normal faults active in the Early Cretaceous; normal faults active in the Oligocene; and negative inverted faults active in the Early Cretaceous and Oligocene. These faults constituted 12 geometric styles in NE-trending belts at various stratigraphic levels, and were formed by compression, strike-slip, extension and inversion. The temporal development of structural styles promoted the formation and reconstruction and finalization of structural traps, while regional unconformities and open reverse and strike-slip faults provided migration pathways for petroleum to fill the traps. In general, potential traps that formed by compressional movement and strike-slip movement in the late Late Jurassic are primarily faulted anticlines. Those traps developed in Carboniferous rocks and are located in the southwestern region of the Eastern Depression, being controlled by NNE-NE-striking reverse and transpressive faults.
