“…This kind of the "flower-structure" with a dip-slip component is widely observed in the BBB (Hu, Jiang, Fu, Li, & Chen, 2016;Wu et al, 2013; and sometimes noted as the "flower-like structure" (Liu, Dong, & Wang, 2010;Zhan et al, 2012). The formation mechanism was studied and illustrated as a result of wrench activity imposed on pre-existing extension faults (Wu et al, 2013;Yixin et al, 2018), which has also been confirmed by physical modelling experiments (Richard & Krantz, 1991;Hu et al, 2019).…”

The Zhangjiakou‐Penglai Fault Zone (ZPFZ) is an NW‐trending strike‐slip fault zone in Eastern China that contains abundant petroleum resources and has induced massive seismic hazards. It is left‐lateral and behaves as a conjugate relationship with the Tan‐Lu Fault Zone (TLFZ). Present studies on the ZPFZ are mainly conducted on its seismology and field exposure features, with subsurface characteristics and evolution history poorly understood. In this study, we investigated the ZPFZ in the western offshore Bohai Bay Basin based on the detailed interpretation of 3D seismic data, specializing in subsurface geometric characters and evolution history. The profile flower structure and plan broom‐like pattern featured the ZPFZ in the study area and indicate its sinistral strike‐slipping. We further investigated and discusssd the Cenozoic evolution history based on evidence in (a) distinguished tectonics in fault releasing and restraining bends, (b) strata thickness map before and after the strike‐slipping, and (c) geometry of composite flower structures. The result suggests the evolution of the ZPFZ mainly comprises three stages: (a) the initial extension from 65 to 38 Ma, (b) the sinistral strike‐slipping in transtension from 38 to 25 Ma, and (3) the sinistral strike‐slipping in transpression from 25 Ma to present. The proposed evolution of the ZPFZ had good consistency with that of the conjugate TLFZ and was closely related to the Cenozoic surrounding plate tectonism, especially the Pacific Plate subduction.

“…The Jinzhou area in the western Liaoning Province, located in the east of the NCC (Zhao G et al, 2005; Figure 1), hosts abundant mineral, oil, and gas resources. Mineralization occurred mainly in the Mesozoic (Zhai M et al, 2019), while oil-and gas-bearing layers were mainly deposited during the Cenozoic (Li W et al, 2018(Li W et al, , 2019Hu Z et al, 2019aHu Z et al, , 2019b. From Cenozoic onward, the area has experienced continuous basin formation and uplift due to coeval fault block activity and regional tectonic uplift (Zhang J et al, 2017;He J et al, 2018;Li W et al, 2018Li W et al, , 2019Hu Z et al, 2019aHu Z et al, , 2019b.…”

The Mesozoic Yanshanian Movement affected the tectonic evolution of the North China Craton (NCC). It is proposed that Mesozoic cratonic destruction peaked ~125 Ma, possibly influenced by subduction of the western Pacific Plate beneath the Euro-Asian Plate in the Early Cretaceous. The southern Jinzhou area in the eastern block of the NCC preserves records for the tectonic events and related geological resources. Studies of the regional stress field evolution from the Cretaceous to Cenozoic can enhance our understanding of the tectonics and dynamics of the NCC. Borehole image logging technology was used to identify and collect attitudes of tensile fractures from 11 boreholes, which were subdivided into four groups according to dip directions, i.e., NNW-SSE, NWW-SEE, W-E and NE-SW. Their development was mainly controlled by the regional tectonic stress field while temperature, lithology, and depth contributed to some extent. The area was characterized by NNW-SSE-and NWW-SEE-oriented extension in 136-125 Ma in the Early Cretaceous. Subsequently, it has successively undergone W-E-and NE-SW-oriented extension in 125-101 Ma and after 101 Ma. This counterclockwise trend has persisted to the present, probably related to oblique subduction of the Pacific Plate and is characterized by ongoing nearly N-S-oriented extension and NEE-SWW-oriented compression.

“…The formation and evolution of this subbasin is mainly controlled by diverse faults, which have caused the most important tectonic deformations in this subbasin. Various fault types have developed in the LDB, which include extensional, strike-slip, and transtensional faults (Hu et al, 2018;Hu P et al, 2019;Hu Z W et al, 2019;Liu Y M et al, 2019). According to their orientations, the faults in the Liaodong Bay subbasin can be divided into three groups: NNEdirected, NE-directed, and NEE-or nearly E-W-directed, among which there are seven main NNE-directed faults, and the secondary fault directions are diverse (Cheng et al, 2015;Nan et al, 2015;Xu et al, 2015;Wu et al, 2016;.…”

WNW-directed faults are widespread in eastern China, but debates regarding their distributions and evolutionary processes remain unsettled. Based on the latest 3-D seismic data, a series of WNW-directed faults south of the Liaodong Bay subbasin was identified, for which the evolution and formation mechanisms were discussed. The results show that four WNW-directed faults are characterized by poor continuity and nearly parallel orientations. Vertically, they exhibit listric geometries and cut through Paleozoic and Mesozoic formations. Since the late Triassic, these faults began as reverse faults under nearly S-N horizontal compression. In the Jurassic, those faults maintained their reverse-faulting activities with dramatically decreased intensities. In the Early Cretaceous, the WNW-directed faults were changed into normal faults under regional extension and were influenced by the sinistral strike-slip movement along the Tan-Lu fault zone. In the Late Cretaceous, the WNW-directed normal faults probably stopped moving due to a regional compressional event. During the Paleogene, the WNW-directed faults were reactivated with decreased intensities and were cut by NNE-directed faults. Here, we emphasize that the evolution of the WNW-directed faults could shed light on the regional tectonics. The WNW-trending faults that developed in the Liaodong Bay subbasin are closely related to the faults in the Yanshan orogenic belt. Therefore, investigating the characteristics and origin of WNW-induced faults will provide evidence for the tectonic evolution of the North China Block. In addition, the development of WNW-directed faults in the southern Liaodong Bay subbasin was conducive to the formation of buried Mesozoic and Paleozoic hills and hydrocarbon accumulations. In addition, we suggest that the compressional segment of the conjugated strike-slip transition zone that was formed by the interaction of the WNW- and NNE-directed strike-slip faults was conducive to hydrocarbon accumulations.
