The Process of Tectonic Inversion and Disintegration in the Dasanjiang Unified Basin, Northeast China: Constraint From Low-Temperature Thermochronology

Abstract

The Dasanjiang basin group in Northeast China contains more than ten Mesozoic–Cenozoic sedimentary basins. Much evidence shows that they were a unified large-scale depression lacustrine basin in the Early Cretaceous; however, destruction processes and mechanisms after the formation of the unified lacustrine basin are some of the key issues restricting basic research and oil and gas exploration in the Dasanjiang area. In this study, we carried out low-temperature thermochronology and thermal history inversion on samples from the main basins in the Dasanjiang area to finely restore the destruction process of the unified basin. The results show that since the Early Cretaceous, the Dasanjiang area has experienced three major positive tectonic inversions: 100 Ma~90 Ma, 73 Ma~40 Ma, and 23 Ma~5 Ma. The unified basin was destroyed by compression and uplift and gradually disintegrated. The basin gradually changed from initial unified evolution to differential evolution and finally formed the isolated appearance of each basin. The aforementioned three-stage positive tectonic inversion time limits basically corresponded to the changing periods in the movement direction, subduction angle, and movement speed of the paleo–Pacific Ocean plate. It is believed that the movement and reorganization events of the plates on the Pacific side dominated the formation, destruction, and disintegration of the Dasanjiang prototype basin, which was the main dynamic mechanism of the tectonic evolution of the Mesozoic and Cenozoic basins in the study area and Northeast China.

Coupling Between Exhumation and Subduction: A Case Study From the Southern Great Xing'an Range, NE Asia

“…23 Ma, Y. P. Zhang et al., 2022) and the GXR (ca. 25 Ma, 15 Ma, Y. Li et al., 2019) (Figure 3c), and tectonic subsidence and deposition in the eastern Sanjiang basin (Y. P. Zhang et al., 2022).…”

“…110–90 Ma, Figure 3a), extension driven by slab roll‐back and lithospheric delamination had not yet reached the eastern continental margin which was still in a compressive setting arising from the Jurassic flat‐slab tectonic setting. As a result, the Liaodong, Jiaodong peninsulas on the eastern continental margin experienced exhumation during shortening (Figures 2e and 3a, Yang et al., 2021; Pang et al., 2022; Y. P. Zhang et al., 2022; Zhou et al., 2022) associated with folding and thrusting in the Sanjiang basin (Shi et al., 2008) and Nadanhada terrane (Lan et al., 2022) with a relatively high subduction velocity of ca. 12–15 cm/yr (Müller et al., 2016).…”

“…In addition, the change in subduction direction of the PPO from NNW to NWW at ca. 110 Ma also likely induced shortening along the eastern continental margin (Bendick & Ehlers, 2014; S. Li et al., 2019; Y. P. Zhang et al., 2022). Furthermore, the first phase of tectonic inversion in Songliao basin and its vicinity at ca.…”

Dating Strike‐Slip Ductile Shear Through Combined Zircon‐, Titanite‐ and Apatite U–Pb Geochronology Along the Southern Tan‐Lu Fault Zone, East China

“…In SE China, such an event is well‐documented as an unconformity between the Lower Cretaceous and Upper Cretaceous volcanic series (120–110 Ma; Ren & Zhang, 2021), and top‐to‐NW thrusting along the Lianhua Shan Fault of SE China (118–108 Ma; J. H. Li et al., 2014; J. H. Li et al., 2020). In NE China, such contraction is recorded by a stratigraphic unconformity that punctuated the Early Cretaceous syn‐rift stage to the post‐rift stage in sedimentary basins (after 125 Ma; Q. Zhang et al., 2017; Z. Q. Li et al., 2021), rapid uplifting events during late Early Cretaceous time (110–100 Ma; Zhou et al., 2022; Y. P. Zhang et al., 2022). Though the specific tectonic dynamic mechanism of this short compressional event remains unclear, we infer that it most likely resulted from the global plate reorganization during the late Early Cretaceous epoch and followed acceleration of the oblique subduction of the Paleo‐Pacific Plate (111–100 Ma; Matthews et al., 2012; Olierook et al., 2020).…”
