“…The Shenhu Uplift was gradually submerged and unable to provide sediments to form fan deltas, while the large-scale meandering river delta sourced from the Pearl River in the north became the dominant deposition system [50]. In this stage, the distribution pattern of depositional systems was mainly controlled by sea-level change and sediment supply, which have been documented in previous studies [66].…”

“…The diversity and complexity of sequence architecture are closely associated with the tectonic evolution process [7,21,66]. The dynamic evolution process of sequence architecture can be divided into three stages: (1) During the rifting stage, the steep slope fault belt and steep-fault bending belt were developed in the footwalls of the Zhusannan and No.2 Fault, respectively (Figure 11).…”

“…( 3) During the post-rifting stage, the end of tectonism caused the cessation of differential subsidence, and the previously developed sequence patterns were replaced by the flat continental shelf belt (Figures 6-9). The depositional systems and their stratal stacking patterns were dominantly controlled by sea-level change and sediment supply [66], and tectonic activities had little effect on the sequence architecture.…”

Investigating the deposition evolution and stratal stacking patterns in continental rift basins is critical not only to better understand the mechanism of basin fills but also to reveal the enrichment regularity of hydrocarbon reservoirs. The Pearl River Mouth Basin (PRMB) is a petroliferous continental rift basin located in the northern continental shelf of the South China Sea. In this study, the depositional evolution process and stacking pattern of the Zhu III Depression, western PRMB were studied through the integration of 3D seismic data, core data, and well logs. Five types of depositional systems formed from the Eocene to the Miocene, including the fan delta, meandering river delta, tidal flat, lacustrine system, and neritic shelf system. The representative depositional systems changed from the proximal fan delta and lacustrine system in the Eocene–early Oligocene, to the tidal flat and fan delta in the late Oligocene, and then the neritic shelf system in the Miocene. The statal stacking pattern varied in time and space with a total of six types of slope break belts developed. The diversity of sequence architecture results from the comprehensive effect of tectonic activities, sediment supply, sea/lake level changes, and geomorphic conditions. In addition, our results suggest that the types of traps are closely associated with stratal stacking patterns. Structural traps were developed in the regions of tectonic slope breaks, whereas lithological traps occurred within sedimentary slope breaks. This study highlights the diversity and complexity of sequence architecture in the continental rift basin, and the proposed hydrocarbon distribution patterns are applicable to reservoir prediction in the PRMB and the other continental rift basins.

“…In the past few decades, the structural characterization of the PRMB has been one of the most studied targets (e.g., Shi et al, 2020;Huang et al, 2018;Zhang et al, 2021;Ye et al, 2020;Zhao et al, 2020;Hui et al, 2022;Ge et al, 2022). However, most of the studies mainly focus on the NE/NEE-trending faults since they control the basin's overall architecture (e.g., Liu et al, 2018;Ye et al, 2018Ye et al, , 2020Zhao Y et al, 2018;Zhou et al, 2018;He et al, 2019;Zhou et al, 2019;Zhou et al, 2019;Ma B et al, 2020;Camanni and Ye, 2022;Suo et al, 2022).…”

The Yanjiang-Yitong’ansha Fault Zone (YYFZ) traverses the Pearl River Mouth Basin (PRMB) and plays an essential role in basin formation and hydrocarbon accumulation in the PRMB. Because of the lack of seismic data, its distribution, evolution, and effect on the basin evolution in the Cenozoic are poorly known. Based on a detailed interpretation of 3D multi-channel seismic data and previous research results, the YYFZ was identified and characterized. It comprises a series of NW-trending strike-slip faults that exhibit horsetail and en echelon structures in the map view and flower-like or Y-shaped structures in the profile view. By comprehensively analyzing the Paleogene migration of depocenters, activity characteristics of the YYFZ-related faults, and the relationships between faults and sedimentary sequences along the YYFZ, we propose the sinistral motion of the YYFZ initiated at about 35 Ma. The YYFZ served as a transfer zone during the intense rifting in the PRMB from 65 to 35 Ma. Then due to the combined effect of the Indian-Eurasian collision to the west, the Pacific subduction to the east, and the proto-SCS slab-pull to the south, it became a sinistral transtensional fault from 35 Ma to 16.5 Ma. Our results highlight the significant role of the NW-trending fault systems in the basin formation and the regional tectonic evolution of the PRMB.

“…Therefore, the theory and method of sequence stratigraphy have been widely used in lacustrine basins. The formation of a marine clastic sequence is mainly controlled by the global sea level [5][6][7][8], while more attention will be paid to the tectonic activity, climate change and other factors of basin-filling evolution in continental rift basins [9,10]. In recent years, Chinese scholars have made important progress in the sequence-stratigraphy evaluation of lacustrine basins [11][12][13][14][15].…”

The sedimentary characteristics of the Neogene in the eastern Liaodong area are poorly studied, which restricts the oil and gas exploration in this area. Based on the current seismic, logging, drilling, and core data, we have studied the sequence stratigraphy and sedimentary characteristics of the Neogene in the eastern Liaodong area. Ultimately, we identified the controlling factors of sedimentation and established the depositional model. In this study, six sequence boundaries of the Neogene were identified and can be divided into five third-order sequences. The sedimentary evolution can be divided into four stages: braided river delta, meandering river delta with a low sand-stratum ratio, meandering river delta with a high sand-stratum ratio, and meandering river delta. Both the palaeotectonic movements and paleoclimate changes of the Neogene influence the periodical fluctuation of the lake level and then control the vertical evolution of the sedimentary types. The paleogeomorphology controls the macroscopic distribution of the sedimentary facies zone, the paleo-valleys that are associated with the strike-slip faults control the channel strike, and the fault slopes at the edge of the lacustrine basins control the sand redistribution of the delta front.
