Special Issue Information

Dear Colleagues,

Following the fruitful outcomes of the first edition, which published a series of high-quality contributions on sedimentary evolution, reservoir characterization, diagenetic processes, and paleoenvironmental reconstruction in lacustrine basins, we are pleased to announce the launch of the Second Edition of the Special Issue on Lacustrine Sedimentology and Reservoir Systems.

In recent years, research on lacustrine basins has made significant progress by integrating sedimentary facies analysis, pore structure characterization, mineralogical and geochemical proxies, and advanced sequence stratigraphy. The first edition featured diverse case studies from major basins in China, South Asia, and beyond, highlighting the global significance of lake basins in unconventional oil and gas exploration. Building on this foundation, the second edition aims to further expand the scope by encouraging cross-disciplinary approaches and comparative studies across different basins worldwide.

We welcome contributions that address, but are not limited to, the following themes:

  • High-resolution reconstruction of sedimentary cycles and stratigraphic architecture in lacustrine systems;
  • Quantitative characterization of diagenetic processes and pore structure evolution in tight reservoirs;
  • Multi-scale coupling between tectonics, climate, and sedimentary processes in lake basins;
  • Geochemical and mineralogical proxies for paleoenvironment and reservoir quality assessment;
  • Innovations in methodologies, including digital outcrop modeling, isotopic tracers, and big-data analytics;
  • Comparative case studies from different basins that highlight global diversity in lacustrine systems.

This Special Issue aims to provide a platform for the latest advances in theory, technology, and practice, thereby fostering collaboration among sedimentologists, reservoir geologists, and geochemists. We look forward to receiving your contributions and continuing to advance research in this vibrant field.

Calcareous sandstones, acting as sealing layers, play a crucial role in hydrocarbon accumulation of formations with high sand content (sand content > 80%). However, the genetic mechanisms, sealing mechanisms, and effectiveness of calcareous sandstones remain unclear. This study takes the Zhuhai–Enping formations in the Panyu A Sag as an example. By comprehensively analyzing data from well logs, cores, cast thin sections, elemental geochemical analysis and carbon–oxygen isotopes, the genetic mechanisms, development patterns, and controlling effects on hydrocarbon accumulation of calcareous cement layers are investigated. The main findings are as follows: (1) The calcareous sandstone cements are mainly composed of dolomite, ankerite, and anhydrite. With increasing burial depth, dolomite transitions from micritic dolomite to silt-sized and fine-crystalline dolomite, and finally to coarse-crystalline dolomite. (2) The local transgression provided ions such as Ca2+ and Mg2+, forming the material basis for early dolomite formation. As burial depth increased, the diagenetic environment shifted from acidic to alkaline, leading to the dolomitization of early-formed calcite and the formation of ankerite. (3) The high source-reservoir displacement pressure difference effectively seals hydrocarbon accumulation. Vertically interbedded tight calcareous sandstones and thin marine transgressive mud-stones collectively control efficient hydrocarbon preservation and enrichment. This research addresses the current limits in the study of “self-sealing sandstone layers,” and provides new geological insights and predictive models for hydrocarbon exploration in sand-rich settings.

Lacustrine fine-grained sediments commonly exhibit well-developed laminations, with significant variations in structural characteristics such as thickness and continuity, which are closely related to depositional environments and genetic processes. This paper focuses on the characteristics and formation mechanisms of the upper Es4 to lower Es3 members of the Shahejie Formation in the Dongying Sag. Through polarized light microscopy, field-emission environmental scanning electron microscopy (FE-SEM), electron probe microanalysis (EPMA), and X-ray diffraction (XRD), we systematically analyzed the types, characteristics, and genetic mechanisms of laminations in fine-grained sedimentary rocks. Results indicate that the mineral composition of these rocks is dominated by carbonates and clay minerals, allowing classification into calcareous and argillaceous mudstones. The types of laminae include calcareous laminae, argillaceous laminae, and silty laminae, which are formed by chemical precipitation, suspension settling, and low-density turbidity currents, respectively. The primary lamination associations are argillaceous–calcareous interbeds and argillaceous–silty interbeds, exhibiting rhythmic cyclicity. In the upper Es4 member, variations in climate, sediment supply, and seasonal factors caused fine-grained sediments to transition from flocculent suspension settling to chemical precipitation, forming periodic intercalations of argillaceous and calcareous laminae. In the lower Es3 member, seasonal turbidity currents triggered the deposition of normally graded silty layers and fine-silty laminae, followed by a return to suspension deposition, resulting in argillaceous–silty interbeds. This study reveals diverse transport and depositional mechanisms of fine-grained sediments under varying hydrodynamic conditions. It provides a new case for understanding the genesis of fine-grained sedimentary rocks and offers geological insights for shale oil exploration and development in the Dongying Sag. Full article
