Summary: This paper presents four best-fit finite element models based on seismic data interpretations to reveal the tectonic development of the Liaodong Bay Subbasin and the Bohai Bay Basin in eastern China. The change in extension directions led to a strike-slip transition of the Tan-Lu Fault Zone from normal to dextral transtensional in the middle-late Eocene, transforming the basins from extensional to dextral transtensional. This transformation was likely triggered by the kinematic adjustment of the Pacific Plate in the middle-late Eocene and maintained by the Indian-Asian collision in the rest of the Cenozoic.

Summary: The study shows the presence of Paleozoic-Mesozoic metamorphic massifs and young fault systems in the west of the Biga Peninsula. Three stress phases were identified in the region between the Neogene and Quaternary, with NW-SE extension dominating in the first phase, NNE-SSW compression prevailing in the second phase, and NE-SW extension in the third phase. The North Anatolian Fault System played a significant role in the morphotectonic development of the region, particularly in the Late Pleistocene-Holocene period.

Summary: Various types of early Palaeogene calderas indicating transtensional and transpressional structures have been identified in southern Sikhote-Alin. These volcanic structures formed due to left-lateral displacements within the territory. The analysis shows a regional S-shaped structure named the 'sinistral kink band of southern Sikhote-Alin'. The early Palaeogene magmatic activity is considered as a marker of left-lateral displacements due to oblique interactions between continental and oceanic plates.

Summary: In this study, the structure and fault characteristics of the Eastern and Western Depressions of the Liaohe Subbasin were investigated using 3D seismic data. The results show that the main faults in the Western Depression exhibited extensional motion during the Palaeocene, while the Eastern Depression exhibited significant right-lateral motion during the Oligocene. The Cenozoic evolution of the subbasin can be divided into four stages, and the reactivation of pre-existing strike-slip faults plays a major role in the evolution and strain partitioning.

Summary: The carbonate-rich rocks in West Junggar were formed during the Eocene due to the reactivation of crustal-scale strike-slip fault zones by the Indian-Eurasian collision. These rocks have similar chemical compositions and geological structures to most sedimentary carbonates, distinct from mantle-derived carbonatites.

Summary: The study of the structural and geochronological characteristics of the Dabie Orogen in the southeastern corner reveals that the Tan-Lu Fault Zone and Xiangfan-Guangji Fault Zone terminate as thrust faults, indicating continental-scale N-S compression in eastern China during the late Early Cretaceous.

Summary: Understanding the development of syn-rift carbonate systems is complex, and their facies distributions can sometimes be difficult to predict due to key factors such as tectonics, eustasy, palaeogeography and climate. The study in SE Dahra Platform demonstrates that synsedimentary faults control reservoir architecture and predict heterogeneous distributions of carbonate facies, with local tectonic deformations and sea-level changes being primary controls on platform geometry and facies distributions.

Summary: The tectonic histories of continental rift basins are complex, involving multiple episodes of subsidence, extensional and strike-slip tectonic activities. This study in Liaodong Bay Sub-basin reveals different types of paleo-valleys and the evolution of sedimentary systems. Tectonic activity, paleogeomorphology and climate conditions all played significant roles in influencing sedimentation processes in the basin.

Summary: Based on seismic and fault architecture data, this paper identifies three stages of Cenozoic extension in the Pearl River Mouth Basin, including NE-SW-directed strike-slip faults, N-S-directed strike-slip and oblique faults, and SE-NW-oriented slow spreading. These findings contribute to a better understanding of the opening mechanism of the South China Sea and lithospheric thinning processes.

Summary: By studying the crustal structure and seismic activity of the Tan-Lu Fault Zone, we have identified the depth distribution of the fault zone and the presence of low-velocity and low-resistivity anomalies, indicating the possible presence of fluids in the faulted rocks.

Summary: This study provides detailed seismic interpretation and tectonic analysis of the Yangjiang Sag in the northwestern Pearl River Mouth Basin, revealing its tectonic evolutionary history. The analysis suggests a dextral transtensional setting during the Paleocene to Miocene, with successive strike-slip motions in ENE and WNW directions. The study also identifies thrust fault systems in the basement that were partially and selectively reactivated during the Cenozoic, resulting in the formation of rhombic-shaped sags with cross-basin fault zones.

Summary: This study focuses on the geometry and kinematics of the West Helanshan fault, situated at the junction of the northeastern Tibetan Plateau, Alxa, and Ordos blocks. The fault is divided into three segments, with the northern and middle segments showing right-lateral strike-slip motion and the southern segment exhibiting reverse motion. The fault poses a high earthquake hazard as it cuts through a county town with a population of about 100,000. Based on the findings, a limited north-northeastward extrusion model is proposed for the southern Alxa Block.

Summary: This study examines a portion of the Tan-Lu fault zone in East China and reveals two phases of sinistral ductile shear deformation. The main phase occurred at around 142-140 Ma, while a later phase occurred at around 118-108 Ma. These findings provide new insights into the early Cretaceous shear deformation history in East Asia.

Summary: Through paleomagnetic and U-Pb geochronological studies of the volcanic rocks on the Jiaodong Peninsula, it is found that the Tan-Lu Fault experienced strike-slip movement in the Mesozoic, providing new constraints on the timing and magnitude of the displacement.
