“…It is well known that a reactivation of Mesozoic sinistral strike‐slip faults to Cenozoic dextral strike‐slip faults occurred on the TLFZ (Allen et al, , ; Mercier et al, ; Xu et al, ; Xu & Zhu, ). Both our recent detailed investigations (Huang et al, , , , ) and other studies (Hsiao et al, ; Teng et al, ) showed that the Cenozoic dextral strike‐slip motion on the TLFZ initiated at about 40 Ma and was a reactivation of Mesozoic sinistral strike‐slip faults and early Paleogene (65–40 Ma) normal faults. The Cenozoic dextral strike‐slip motion after 40 Ma produced all the flower structures discussed in this study.…”

“…It is generally agreed that this fault zone experienced sinistral movement during the Mesozoic (Gilder et al, ; Xu & Zhu, ; Xu et al, ; Zhu et al, , ), while during the Cenozoic this fault zone was reactivated as a dextral strike‐slip fault (Allen et al, , ; Hsiao et al, ; Huang et al, , , ; Lin et al, ; Mercier et al, ; Zhu et al, ). The TLFZ runs through the offshore part of the Bohai Bay Basin (Figure b), a Cenozoic rift basin with two evolutionary stages (i.e., a Paleogene synrift stage and a Neogene‐Quaternary postrift stage) (Figure ), and has caused complex tectonic changes to the region including the preferential accumulation of hydrocarbons (Allen et al, , ; Chen & Nabelek, ; Gong et al, ; Huang et al, ). In the Bohai Bay Basin during the Cenozoic, subsequent to a period of extensional deformation (65 Ma to 40 Ma), the TLFZ was reactivated around 40 Ma as a dextral divergent wrench fault (Allen et al, , ; Hsiao et al, ; Huang et al, , , , ; Teng et al, ) (Figure ).…”

“…This claim is also supported by the following fact. Abundant oblique extensional structures (i.e., negative flower structure) along the straight sections of the TLFZ indicate the dextral transtension on this wrench fault zone (Huang et al, , ), and these structures were developed continuous without any imprint of inversions on faults and strata (Figure ), indicating the absence of switch from oblique normal faulting to oblique reverse faulting along this fault zone. Furthermore, we suggest that these inversions contain several independent ones which might occur at the same time, while each inversion is very local and has a very limited influenced area, only affects a few faults.…”

“…The TLFZ runs through the offshore part of the Bohai Bay Basin (Figure 2b), a Cenozoic rift basin with two evolutionary stages (i.e., a Paleogene synrift stage and a Neogene-Quaternary postrift stage) ( Figure 3), and has caused complex tectonic changes to the region including the preferential accumulation of hydrocarbons (Allen et al, 1997(Allen et al, , 1998Chen & Nabelek, 1988;Gong et al, 2010;Huang et al, 2014). In the Bohai Bay Basin during the Cenozoic, subsequent to a period of extensional deformation (65 Ma to 40 Ma), the TLFZ was reactivated around 40 Ma as a dextral divergent wrench fault (Allen et al, 1997(Allen et al, , 1998Hsiao et al, 2004;Huang et al, 2012Huang et al, , 2014Huang et al, , 2015Huang et al, , 2016Teng et al, 2016) (Figure 3). Since this time, the TLFZ has induced a number of divergentwrench-related structural deformation, including numerous flower structures (Huang et al, 2015(Huang et al, , 2016Teng et al, 2016).…”

Flower structures are typical features of wrench fault zones. In conventional studies, two distinct kinds of flower structures have been identified based on differences in their internal structural architecture: (1) negative flower structures characterized by synforms and normal separations and (2) positive flower structures characterized by antiforms and reverse separations. In addition to negative and positive flower structures, in this study, a third kind of flower structure was identified in a divergent‐wrench fault zone, a hybrid characterized by both antiforms and normal separations. Negative flower structures widely occur in divergent‐wrench fault zones, and their presence indicates the combined effects of extensional and strike‐slip motion. In contrast, positive and hybrid flower structures occur only in fault restraining bends and step overs. A hybrid flower structure can be considered as product of a kind of structural deformation typical of divergent‐wrench zones; it is the result of the combined effects of extensional, compressional, and strike‐slip strains under a locally appropriate compressional environment. The strain situation in it represents the transition stage that in between positive and negative flower structures. Kinematic and dynamic characteristics of the hybrid flower structures indicate the salient features of structural deformation in restraining bends and step overs along divergent‐wrench faults, including the coexistence of three kinds of strains (i.e., compression, extension, and strike‐slip) and synchronous presence of compressional (i.e., typical fault‐bend fold) and extensional (normal faults) deformation in the same place. Hybrid flower structures are also favorable for the accumulation of hydrocarbons because of their special structural configuration in divergent‐wrench fault zones.

The western offshore Bohai Bay Basin (BBB) is located at the intersection of the Zhangjiakou–Penglai Fault Zone (ZPFZ) and the Huanghua–Dongming Fault Zone (HDFZ). Exploration experience proves that faults' activity played an import role in hydrocarbon accumulation, whereas characters and evolution of the fault system remain poorly understood. In this study, characters and evolution of the fault system were investigated through abundant seismic data from oil fields. Six NE and two NW strike‐slip faults were identified by composite flower structures on seismic profiles and show broom‐like or en echelon patterns with different scales in plan view. Massive flower‐like structures were observed, which serve as an indicator of early extension and consequent shear activity. Based on published physical modelling, the different plan forms and scales of strike‐slip faults were deciphered as an outcome of diverse strike‐slip displacements. The character and evolution of the fault system were investigated using fault activity rate, balanced restoration, and typical‐structure analysis. The result suggests that the NW‐trending faults have a more intense fault activity and strike‐slip faults in the north, and the east have larger displacements than those in the south and the west. Considered together with the basin evolution, we suggested a three‐stage fault evolution model for the fault system in the study area, mainly comprising (a) early extension; (b) mid transtension, and (c) late transpression, which resulted from multiple geodynamic events during the Cenozoic. Our study reveals that the ZPFZ and the HDFZ have a significant impact over faults in the western offshore BBB, which is demonstrated by unusual intense fault activity in the extension period and different strike‐slip displacement in the strike‐slip period.

Neogene–Quaternary postrift tectonic reactivation of the Bohai Bay Basin, eastern China

Abstract: 5The Bohai Bay Basin, located in the eastern China, is considered to be a Cenozoic rifted basin. 6 The basin is atypical in terms of its Neogene-Quaternary post-rift subsidence history in that it 7 experienced intensive tectonic reactivation, rather than the relative tectonic quiescence
