“…The Pacific Plate subducts towards Eurasia at a moderate convergence rate ranging from 77 mm/a to 90 mm/a since Dongying Formation (32.8 Ma) deposition. The India-Australia Plate still keeps previous convergence rate and collision direction (Maruyama & Seno, 1986;Ren et al, 2002;Wakita, 2013) (Yan et al, 2022;T.

“…The Philippine Plate collides with south‐western Japan since the 30 Ma, resulting in southward movement of eastern block of Tan‐Lu Fault Belt under joint interaction of the Pacific Plate and the Philippine Plate during the Oligocene deposition. The evolution of Liaodong Bay is remarkably influenced by dextral shear activity during this period with strike‐slip intensity weakens from eastern portion to western portion of Liaodong Bay (Yan et al, 2022; T. Yang et al, 2016; Zhang et al, 2017; G. Zhu et al, 2012). The rate of tectonic subsidence remains low, with an average of 0.121 mm/a (Fang et al, 2017; Farangitakis et al, 2021; Hsiao et al, 2010; Huang et al, 2015).…”

The fault activity, tectonic subsidence history, and geodynamics are analysed based on borehole information and seismic datasets from Liaodong Bay. The results reveal that the faults are intensely active (resulting in the faults that are characterized by more lengths and more throws) both in the northern and southern portions of the study area, while the faults are not active in the central portion of the study area during Kongdian Formation and Shahejie Formation deposition. However, the faults are generally more active in the northern portion of the study area than that in the southern portion of the study area. In contrast, the faults are intensely active in central and southern portion of the study area during Dongying Formation deposition. The numerous syn‐depositional faults, which are intensely active, result in southward movement of depositional centre. The tectonic subsidence history of wells (including well JZ‐A, well JZ‐B, well JZ‐C, well JZ‐D, well JX‐A, and well SZ‐A) in Liaodong Bay indicates that it shows obvious episodic tectonic evolution during the Palaeogene in Liaodong Bay. The episodic tectonic movement (initial rifting, rifting climax, thermal subsiding, and strike‐slip rifting) corresponds to Kongdian Formation and Shahejie Formation deposition, and Dongying Formation deposition, respectively. The spatio‐temporal variation of tectonic subsidence history is closely related to fault activity. The analysis results of balanced cross‐sections show that faults are intensely active during Dongying Formation deposition. However, a few faults are much active than that during Shahejie Formation deposition. There is a slight decrease in tectonic activity intensity during Kongdian Formation and Shahejie Formation deposition. In contrast, there is a significant decrease in tectonic activity intensity during third‐member to first‐member of Dongying Formation deposition. The tectonic activity intensity tends to cease by the end of Dongying Formation.

“…The simple shear process in the upper crust is carried out along NW‐SE direction. The detachment surface of westward‐inclined faults at a low angle extends to the deep inside in a ladder shape (Tapponnier, Peltzer, Le Dain, Armijo, & Cobbold, 1982; Yan, Shi, Yuan, Yan, & Liu, 2022; Yang et al, 2022; Yu & Koyi, 2016). In the process of detachment, the tectonic extension in the upper crust in the east is gradually transmitted to the lower crust and lithospheric mantle in the west, which makes inconsistency between intense rifting area and lithospheric thinning area, resulting in an asymmetric profile of depressions in Liaodong Bay along the tectonic extensional direction (Figure 2).…”

Based on seismic interpretation of 18 regional 3D high‐resolution seismic sections across Liaodong Bay, extension amounts, extension rates and extension coefficients of different seismic sections from the south to the north are calculated by employing balanced section technique. Then, spatio‐temporal distribution of extension amounts is characterized and interpreted. Finally, the analysis of genetic mechanism is conducted and analysed. The results indicate that tectonic evolution in the Paleogene of Liaodong Bay is characterized by episodic extension. Furthermore, spatio‐temporal distribution of extension amounts is relatively uneven. In terms of space, extension amounts are mainly caused by extensional displacement of main depression‐controlled boundary faults and syn‐depositional faults in the depression. In addition, extensional amounts along main depression‐controlled boundary faults are characterized by larger displacement. In terms of time, the periods for horizontal extensional movement can be divided into three stages: The Palaeocene‐Early Eocene (Kongdian Formation‐third member of Shahejie Formation), Middle‐Late Eocene‐Early Oligocene (first and second member of Shahejie Formation) and Middle‐Late Oligocene (Dongying Formation). Among them, extension during the Palaeocene‐Early Eocene occurs both in the north and south of Liaodong Bay. However, extension intensity in the north is stronger than that in the south. Extension intensity in the middle and north during Middle‐Late Eocene‐Early Oligocene obviously increases. In contrast, it is dominated by strike‐slip movement during depositional period of Dongying Formation. Therefore, extension intensity is characterized by significant inheritance. Spatial–temporal distribution of extension amounts is predominantly controlled by tectonic evolution and associated tectonic deformation.

“…Previous studies have shown that the subduction components can not only affected the compositions of volcanic arc lavas, but also those of BABBs (Pearce et al, 2005;Pearce and Stern, 2006;Stern, 2001;Tian et al, 2005;Yan et al, 2022). The distinctive geochemical characteristics of volcanic arc lavas and BABBs are attributed to the result of different subduction process (Pearce and Stern, 2006;Yan et al, 2019).…”

Since the Early Cenozoic, the Philippine Sea Plate (PSP) has undergone a complex tectonic evolution. During this period the Parece Vela Basin (PVB) was formed by seafloor spreading in the back‐arc region of the proto‐Izu‐Bonin‐Mariana (IBM) arc. However, until now, studies of the geological, geophysical, and tectonic evolution of the PVB have been rare. In this study, we obtained in situ trace element and major element compositions of minerals in basalts collected from two sites in the southern part of the PVB. The results reveal that the basalts from site CJ09‐63 were likely formed via ∼10% partial melting of spinel‐garnet lherzolite, while the basalts from site CJ09‐64 were likely formed via 15%–25% partial melting of garnet lherzolite. The order of mineral crystallization for the basalts from site CJ09‐64 was olivine, spinel, clinopyroxene, and plagioclase, while the plagioclase in the basalts from site CJ09‐63 crystallized earlier than the clinopyroxene. Using a plagioclase‐liquid hygrometer and an olivine‐liquid oxybarometer, we determined that the basalts in this study have high H2O contents and oxygen fugacities, suggesting that the magma source of the Parece Vela basalts was affected by subduction components, which is consistent with the trace element composition of whole rock.
