“…Additionally, the lake receives average annual groundwater recharge of about 432 million m 3 , which accounts for 23.43% of the total inflow into the lake [14,15]. Research indicates that Hulun Lake is a tectonic lake that has developed from the long-term accumulation of river water in a tectonic fault basin [16]. The significant difference in the annual water volume between the groundwater and surface water in Hulun Lake is primarily due to the NNE-trending fault zone on the eastern and western banks of the lake, which aligns with the long axis of the lake [17,18].…”

Groundwater is one of the key sources of water recharge in Hulun Lake. In order to trace the location of the confined aquifer of the deep groundwater that recharges the lake, hydrogeochemical characteristic analysis and hydrogen and oxygen stable isotope sampling and analysis were performed on the lake water, phreatic water and multi-layer cretaceous confined water in the same region of the Hulun Lake basin. The hydraulic relationships between the lake and various aquifers were then revealed through the use of hydrogen radioisotopes. The results show that the lake water, phreatic water and confined water are of the HCO3−Na type, and the content of stable isotopes (δD, δ18O) and radioisotopes (δ3H) is in the order of “confined water < phreatic water < lake water”. The main influencing factor of hydrochemical evolution in the phreatic water is the dissolution of feldspar; its age is about 26.66 years, and its renewal rate is nearly 3.75%. The main influencing factor of hydrochemical evolution in the K1y1, K1y2 and K1d1 Cretaceous confined water is evaporite dissolution (i.e., halite, gypsum); their renewal rate is less than 1%, and the discharge condition deteriorates with the increase in the aquifer roof burial depth. Phreatic water in the Jalainur Depression Zone supplies Hulun Lake under the condition of the existence of permafrost cover. The K1d2 confined water of the Lower Cretaceous–Damoguaihe Formation Coal Group II, with the deepest roof burial depth (441 m), shows significant differences in hydrochemistry, δD, δ18O and δ3H from the other K1y1, K1y2 and K1d1 Cretaceous confined waters in the same basin. The renewal rate (nearly 4.32%) of the K1d2 confined water is better than that of the phreatic water, and its hydrochemical characteristics are similar to those of the lake water and phreatic water, indicating that the Cuogang Fault and Xishan Fault, caused by crustal faults, resulted in the hydraulic relationship between the K1d2 confined water, lake water and phreatic water, resulting in drastic interannual changes in the lake water level. This study of lake–groundwater interactions in cold and arid regions can provide a theoretical basis for lakes’ sustainable development.

“…The research on sedimentary characteristics and depositional evolution of coal‐bearing series in terrestrial lacustrine basins has drawn worldwide attention in recent years (Basu et al, 2021; Benayad et al, 2019; Chen et al, 2022; Hou et al, 2023; Lu et al, 2020a; Wainman & McCabe, 2019; Xia et al, 2018, 2019, 2020; Yue et al, 2018). The Qaidam Basin, located in the eastern margin of the Qinghai‐Tibet Plateau, is a typical Mesozoic–Cenozoic basin and covers 150,000 km 2 between latitudes 36° N–39° N and longitudes 91° E–98° E. The Lower–Middle Jurassic rocks at the Qaidam Basin have been proven to be an important succession for hydrocarbon exploration and development (Cao et al, 2012; Hou et al, 2022; Liu et al, 2018; Ritts et al, 1999; Tian et al, 2018; Wang et al, 2005; Yang et al, 2004).…”

Evolution of depositional environment of the Pliensbachian Stage (Lower Jurassic) coal‐bearing series in the Qaidam Basin, NW China

The Qaidam Basin is one of the major coal‐bearing basins in northeastern China with the coal seams mainly preserved in the Lower–Middle Jurassic. The Middle Jurassic sedimentary environment, sequence stratigraphy, paleoclimate, and coal accumulation in the Qaidam Basin have been extensively studied, while the sedimentary characteristics and depositional evolution of the Lower Jurassic coal‐bearing series are less well known. We systematically analysed the facies association, depositional system, basin evolution, and coal accumulation of the Early Jurassic Pliensbachian‐aged coal‐bearing series from the Dameigou section in the northern Qaidam Basin. Five lithological types have been identified, ranging from conglomerates, sandstones, siltstones, and mudstones to combustible organic rocks, which were further subdivided into 12 lithofacies. These lithofacies were grouped into four facies associations, representing the braided fluvial, meandering fluvial, lacustrine, and meandering fluvial‐lacustrine transition deposits, respectively. The Pliensbachian Stage mainly developed as a fluvial‐lacustrine depositional system and an evolution history from braided fluvial to meandering fluvial, then to lacustrine, and finally back to meandering fluvial was reconstructed. We suggest that climate change is the major controlling factor for depositional evolution during the Pliensbachian. The transition of the depositional environment from fluvial to lacustrine in the study area can be attributed to the rapid climatic change induced by volcanism at this interval.

“…The river‐dominated deltaic sequencesare usually among the most comprehensive and heterogeneous depositional systems in lacustrine rift basins with favourable reservoirs below seismic resolution or outside seismic coverage (Al‐hasani et al, 2018; Benayad et al, 2019; Kassab, Hassanain, & Salem, 2014; Khaing et al, 2017; Mahgoub et al, 2016; Richard & Kenneth, 2003; Wang, 2000; Wu, Wu, Qu, Ma, & Guo, 2010; Xia et al, 2018, 2018, 2018, 2020; Xia, Lin, Du, Li, & Li, 2020; Yassin et al, 2018; Zhang et al, 2020). In addition, the reservoir characteristics have long been of great interest in hosting potential petroleum reserves and developing petroliferous petroleum plays.…”

The hydrocarbon discoveries are increasing in deltaic systems in Jurassic Sangonghe Formation in southern Mahu Slope of Junggar Basin in recent years. However, different scales of sedimentological heterogeneities influence reservoir quality and architecture. Consequently, the study aims to employ thin sections, core logs and wireline logs to conduct research to address the issues. The results show that the integrated analysis of conventional cores reveals three facies groups in Sangonghe Formation which are deposited in braided deltaic and lacustrine environment. Each facies group contains several lithofacies given their grain size, sedimentary structures. In addition, the lithofacies types, associations, and wireline responses indicates that Lower, Middle, and Upper Sangonghe Formation is deposited in braided delta plain, braided delta front, and pro‐delta respectively. Moreover, the Sangonghe Formation is characterized by variations regarding sandbody, thickness, geometry, and architecture. The facies distribution and sedimentary environment indicate that accommodation space plays essential controls. The sedimentological heterogeneity controls reservoir quality and architecture from macro‐ to micro‐scale. The macro‐scale insights reflect that the lower and middle Sangonghe Formation shows high connectivity of sandbodies while the upper Sangonghe Formation shows low connectivity of sandbodies. The micro‐scale insights indicate that sandstone types, texture, composition all plays significantly role in controlling reservoir porosity and permeability. Finally, the understandings and insights of reservoir sedimentological heterogeneities assist in better prediction and assessment of reservoir quality and architecture. Finally, it will make contributions to reservoir development, recovery, and productivity for areas with similar sedimentological settings.
