“…The rift extension of the Liaohe Subbasin began in the Palaeocene and experienced the most slip in the Late Eocene (Figure 11b). This extension mechanism is related to the subduction and rollback of the Pacific Plate relative to the Eurasian Plate (Figure 12a; Chen et al, 2022; Li, Qi, et al, 2010; Liu et al, 2004, 2015; Su et al, 2014; Tang et al, 2013; Yang et al, 2018; Zhu et al, 2011). During the Palaeocene, the Pacific Plate was subducted and trapped in the mantle transition zone (Figure 12a), leading to the upwelling of mantle flow (Figure 12b).…”

In rift basins with multiphase extension, the reactivation of pre‐existing faults plays an important role in the evolution and partitioning of deformation. The Liaohe Subbasin is located in the northeastern Bohai Bay Basin, and the Tanlu Fault Zone (TLFZ) runs through it and experienced extension and right‐lateral strike‐slip during the Cenozoic. Therefore, it is an ideal region for studying the deformation and evolution of rift basins. Based on 3D seismic data, we document the structure and fault characteristics of the Eastern and Western Depressions of the Liaohe Subbasin, identify periods of activity on normal and strike‐slip faults, and analyse the evolution and mechanisms of the Cenozoic evolution of this subbasin. Our main results show that (1) the main faults in the Western Depression exhibited extensional motion throughout the Palaeocene, while the Eastern Depression exhibited significant right‐lateral motion during the Oligocene following the early extension stage. (2) The Cenozoic evolution of the Liaohe Subbasin can be divided into four stages: (i) an initial extension stage (the Palaeocene to the Eocene), (ii) an extension stage with initial strike‐slip (Early Oligocene), (iii) a right‐lateral strike‐slip stage (Late Oligocene) and (iv) a postrift stage (after the Neogene). (3) The upwelling of mantle material caused by the subduction and rollback of the Pacific Plate led to the extension of the Liaohe Subbasin from the Palaeocene to the Eocene. The TLFZ began right‐lateral motion at 40 Ma and experienced strong right‐lateral deformation when rifting was weak in the Oligocene and enhanced deformation after 12 Ma. (4) In this multiphase rifting process, under moderate obliquity, strike‐slip deformation is obvious in the areas close to pre‐existing faults, while extensional deformation is obvious in areas farther away. (5) Cenozoic extension and strike‐slip deformation due to partitioning of strain are caused by obliquely reactivation of TLFZ. This study suggests that the reactivation of pre‐existing strike‐slip faults plays a major role in evolution and strain partitioning. Moreover, the results will contribute to future hydrocarbon exploration in multiphase rift basins.

“…The Bohai Bay Basin is a prolific petroleum basin in the center of the eastern part of the North China Craton. , The Carboniferous–Permian succession contains the Benxi, Shanxi, Taiyuan, and Shihezi formations, which were deposited in the Upper Paleozoic. The succession is comprised of thick (178–369 m), unconformable, siliciclastic-dominated, shallow-marine, and paralic deposits overlying Middle Ordovician carbonates .…”

Coal and accompanying shales have gained attention as potential source rocks and reservoirs providing abundant cleaner energy hydrocarbons. Carboniferous−Permian coaly source rocks deposited in North China were investigated using organic−inorganic chemistry, organic petrology, and biomarkers to analyze their hydrocarbon generation potential, maceral components, and depositional environments. Coal of Taiyuan Formation (Taiyuan) and Shanxi Formation (Shanxi) was characterized by type II 1 to III kerogen with good-to-excellent quality. However, carbonaceous mudstone and coaly shale contained type II 2 to III kerogen with poor-to-good quality. More liptinite of sporinite, cutinite, resinite, and hydrogen-rich collodetrinite was present in the Taiyuan coal than that of the Shanxi. Carbonaceous mudstone and coaly shale contained less sporinite, cutinite, and vitrinite. Taiyuan coaly source rocks were deposited in a brackish and anoxic−dysoxic bottom water environment which provided better preservation conditions compared to the fresh−brackish and weak reduction−oxidation environment of Shanxi coaly source rocks. The depositional environment was a critical factor determining the accumulation of organic matter (OM) for the Taiyuan and Shanxi coaly source rocks. Additionally, a flux of hydrogen-rich components of liptinite and vitrinite was also a key factor in the formation of coal, carbonaceous mudstone, and coaly shale. A model of OM accumulation in coaly source rocks was established to predict good-to-excellent source rocks in similar depositional environments.

“…The Bohai Bay Basin, as a Cenozoic extensional basin along eastern Asia, is located in the centre of eastern North China Craton (Chen et al, 2010;Hou & Hari, 2014). It developed in response to the kinematics of adjacent orogenic belts and subduction of the Pacific Plate (Hsiao, Graham, & Tilander, 2004;Su, Zhu, Chen, Min, & Zheng, 2014). The present Bohai Bay Basin is located among northern Yanshan Uplift, eastern Liaodong Uplift, and Luxi Uplift (Hsiao et al, 2004;Hsiao, Graham, & Tilander, 2010).…”

The typical wells in Liaoxi Uplift were selected to conduct studies on high-frequency sequences and their correspondences with the Milankovitch Cycles in Dongying Formation based on integrated analysis of wireline logs and sieve residue logs. The results of well JZ-E show that 37 ultra-short-term cycles, 13 short-term cycles, 8 mid-term cycles, and 5 long-term cycles are identified. Meanwhile, the correspondences between high-frequency sequences and the Milankovitch Cycles in Dongying Formation were analysed based on GR curve of well JZ-E and MATLAB procedure. The correspondences indicate that the Milankovitch Cycles are well preserved in Dongying Formation. The thickness of long-period cycles caused by eccentricity ranges from 2.7963 to 3.9965 m. The thickness of mid-term cycles caused by obliquity ranges from 1.5081 to 2.1126 m. The thickness of short-period cycles caused by precessions ranges from 0.5791 to 1.1269 m. There is a good consistency between high-frequency sequences and the Milankovitch Cycles in Dongying Formation. The mid-term cycle, short-term cycle, and ultra-short-term cycle of high-frequency sequence correspond, respectively, to long-period eccentricity, short-period eccentricity, and precession cycle of the Milankovitch Cycles. Lacustrine fluctuations caused by the change in Earth's orbit play a major role in controlling high-frequency sequences.
