“…Uchimura et al (1996) attributed the driving force of the tectonic rotation to post-Cretaceous large-scale sinistral faulting, up to ~ 800 km, along the Tan-Lu Fault. Although it was an active sinistral fault during the period when the first clockwise rotation is estimated to have occurred (Wang et al 2019), geological evidence does not suggest such large post-Cretaceous sinistral offsets. Lin et al (2003) proposed a clockwise tectonic rotation (i.e., first-phase rotation), primarily based on paleomagnetic data from the Benxi area and the Korean Peninsula (Fig.…”

To construct the Mesozoic apparent polar wander path (APWP) for the inner arc of the southwestern Japanese islands (referred to as southwest Japan) and compare it to that of East Asia, a 110 Ma paleomagnetic pole for southwest Japan was determined. Mudstone and sandstone samples were collected from 16 sites for paleomagnetic analysis in the Lower Cretaceous Inakura Formation of the Inakura area in the central part of southwest Japan. A high-temperature magnetization component, with unblocking temperatures of 670–695 °C, was isolated from 12 sites of red mudstone. Of these, 11 sites revealed a primary remanent magnetization during the Early Cretaceous. The primary directions combined with the previously reported ones provide a new mean direction (D = 79.7°, I = 47.4°, α95 = 6.5°, N = 17), and a corresponding paleomagnetic pole that is representative of southwest Japan (24.6° N, 203.1° E, A95 = 6.8°). The Early Cretaceous paleomagnetic pole, together with the Late Cretaceous and Cenozoic poles, constitute a new APWP for southwest Japan. The new APWP illustrates a standstill polar position during 110–70 Ma, suggesting tectonic quiescence of this region. This standstill was followed by two large tracks during the Cenozoic. We interpret these tracks as clockwise tectonic rotations of southwest Japan that occurred twice during the Cenozoic. The earlier tectonic rotation occurred for a tectonic unit positioned below northeast China, the Liaodong and Korean Peninsulas, and southwest Japan (East Tan-Lu Block) during the Paleogene. The later rotation took place only under southwest Japan during the Neogene. Cenozoic multiphase rifting activity in the eastern margin of the Asian continent was responsible for the tectonic rotations that are observed from the paleomagnetic studies. Intermittent rifting may constitute a series of phenomena due to asthenospheric convection, induced by the growth of the Eurasian mega-continent in the Mesozoic.

“…Tectonically, the Luxi Terrane experienced a complex tectonic evolution and deformation history since the Mesozoic (Grimmer et al, 2002; G. Wang, Li, et al, 2019). During the Indosinian to Yanshan orogen, the Luxi Terrane underwent the intense compression, the direction shifted from SN to NW‐SE, which generated massive folds and thrust nappe (G. Wang, Liu, et al, 2013; F. Yang, Santosh, Glorie, Jepson, & Kim, 2020).…”

The Luxi Terrane is important for understanding the large‐scale extension and lithospheric thinning in eastern North China Craton (NCC) during the Mesozoic to Cenozoic. However, the exhumation/uplift history of the whole region in comparison to its adjacent areas is still unclear. To address this issue, we compiled 892 thermochronological data using jointly Kernel density estimation and linear inversion approaches to identify the exhumation episodes and estimate the temporal and spatial variation of the exhumation rates. The results indicated that these areas all experienced three rapid exhumation episodes, throughout the Early Cretaceous (120–100 Ma), Late Cretaceous‐Palaeocene (90–60 Ma), and Eocene (50–35 Ma). While the existence of synchronous tectonic evolution, the exhumation rates are heterogeneously distributed throughout the Luxi Terrane and neighbouring areas in space and time. We suggest that tectonics may play a role in setting up the regional variation in exhumation patterns. Considering the plate reconstructions and integrating low‐temperature thermochronological studies, the Early Cretaceous rapid exhumation corresponds to extensive craton destruction, linked with the Izanagi slab rollback within a back‐arc extensional setting. The Late Cretaceous‐Palaeocene rapid exhumation is interpreted as a response to continuing craton destruction and lithospheric thinning resulting from the subduction of Izanagi‐Pacific. In the Eocene, we propose that the coupling effect of subduction of Pacific Plate and India‐Eurasia collision can trigger this cooling episode.

“…The TLFZ, a typical strike‐slip fault zone, runs through the eastern border of the BBB (Figure 2), which is generally accepted to have originated from the collision of the South China Block and North China Block in the Late Triassic (Chen et al, 2022; Zhu et al, 2009), and the left‐lateral strike‐slip motion of the TLFZ during the Mesozoic was controlled by the subduction of the Izanagi‐Pacific Plate (Chen et al, 2022; Wang et al, 2019; Zhu et al, 2005). From the Cenozoic, the fault slip changed from normal faulting to right‐lateral motion during the Late Palaeogene (Chen et al, 2022; Wang et al, 2019), but the timing and mechanism of the right‐lateral strike‐slip are still controversial. Present‐day earthquakes have suggested that the fault zone is still active (Fu et al, 2004; Hsiao et al, 2004; Huang et al, 2018; Teng et al, 2016).…”

Cenozoic evolution and deformation in the Eastern and Western Depression of the Liaohe Subbasin, Bohai Bay Basin: Insights from seismic data

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.
