Summary: The study discusses the development of hybrid event beds in submarine lobes, focusing on the relationship between the character of hybrid bed facies and lobe architecture. Proximal to medial lobes exhibit different types of hybrid facies, while distal lobes mainly contain simpler hybrid facies. Lateral lobes have less vertical thickness of hybrid beds compared to frontal lobes, indicating significant differences in the evolution of hybrid beds between lateral and frontal lobes.

Summary: The mechanisms controlling the stacking patterns of deep-water turbidite lobes were studied in the Marulk area of the Norwegian Sea. The study identified the role of autogenic and allogenic forcings in shaping the depositional architecture of turbidite lobes. Autogenic processes were found to regulate sediment dispersal and the evolution of lobe sub-environments, while allogenic forcings controlled axial migration and the overall evolutionary trend of the turbidite lobe complex. The study also proposed an updated approach to deciphering autogenic-dominant and allogenic-dominant processes in turbidite lobe deposits.

Summary: This paper investigates the stabilization in distribution of hybrid stochastic differential equations (HSDEs) through periodically intermittent feedback controls. It is shown that the probability distributions of the solutions will converge to a stationary distribution. Firstly, sufficient conditions for stabilization in distribution of HSDEs are established using the theory of M-matrix and intermittent control strategy. Then, the existence and uniqueness of invariant probability distribution are proven, and the lower bound of the intermittent parameter 8* is obtained. Three numerical examples are discussed to support the theoretical analysis results.

Summary: The carbonate-dominated successions of the Tirgan Formation in the Kopet-Dagh Basin were studied to understand the tectonic and eustatic sea-level effects and autogenic influences on facies changes and sequence stratigraphy. Fourteen facies were identified and grouped into five associations based on depositional settings. A third-order depositional sequence was identified, along with several cycles. The development of the sequences and cycles was controlled by allogenic and autogenic factors. The study provides insights into sedimentary basin evolution and paleogeographic reconstructions.

Summary: Petroleum accumulations in sedimentary basins are controlled by factors such as source-rock distribution, thermal maturity, migration pathways, and traps. The Montney Formation serves as a well-documented example of a hybrid system, where petroleum distribution is influenced by factors like thermal maturity, fluid migration, and pressure compartmentalization. Integrating gas compositional mapping with reservoir pressure data reveals the strong control of the structural framework on petroleum migration routes.

Summary: The study analyzed the spatial variations of grain size and composition in a physically modelled turbidity current deposit. The results showed that grain size coarsened downstream challenging existing notions, input compositions did not match sample compositions indicating variability in sediment gravity flow deposits, and microplastics were concentrated in certain positions but bypassed others. These findings have implications for interpreting environmental signals and predicting microplastic distribution in deep-water depositional systems.

Summary: The lower Siwalik succession in the south-central Kumaun Himalaya records Middle Miocene fluvial sedimentation in the Himalayan foreland basin. Facies analysis reveals sand-dominated channel deposits, as well as mudstone-sandstone and mudstone-dominated overbank deposits. Initially, sedimentation occurred in meandering/anastomosing river systems, with frequent flooding. However, tectonic activities caused incision and uplift of the basin, leading to the cessation of fluvial sedimentation in upland areas. The channel pattern gradually changed to braided type due to tectonic activities and monsoon intensification.

Summary: Interactions between footwall-, hangingwall- and axial-derived depositional systems in rift basins make stratigraphic architecture prediction challenging. Distinguishing between deposits derived from fault-scarp degradation and long-lived catchments is crucial for hydrocarbon exploration. The study emphasizes the need to consider multiple sediment sources for tectono-stratigraphic models in rift basins.

Summary: A revised equation for the hindered settling of non-cohesive particles in fluids is proposed in this study, based on a large dataset from various scientific fields. This equation allows for predictions of settling velocity for different particle sizes, densities, and fluid conditions, with a focus on sediment particles in water. The study also reveals that hindered settling becomes more significant as particle size decreases, and even a small percentage of particle concentration can affect the settling behavior.

Summary: This study investigates the sedimentology and stratigraphy of mudstones in the Laingsburg depocentre of the Karoo Basin, South Africa. It presents criteria to distinguish between slope and basin-floor mudstones and discusses their depositional processes and facies organization. The findings challenge the common attribution of deep-water mudstones to periods of sediment starvation, suggesting mud can be delivered to deep-water environments dominantly by sediment gravity flows.

Summary: This study presents sedimentological evidence of sandy hyperpycnal flow deposits (hyperpycnites) in a series of basin floor lobe complexes associated with a progradational shelf margin in the Eocene of Spitsbergen, Arctic Norway. The abundance of thick-bedded massive sandstones, frequent bed amalgamation, and the distribution of hyperpycnites across the lobes suggest that hyperpycnal flow was the most important mechanism driving lobe progradation. These findings challenge the traditional beliefs about hyperpycnites preserving the waxing-waning signal of single-peaked floods.

Summary: Continental break-up is often accompanied by intracontinental wrenching, leading to the formation of transform margins and transform marginal plateaus. The Falkland Plateau is an example of a transform marginal plateau, where regional wrenching resulted in a mosaic of crustal types in the Falkland Plateau Basin. The uncertainties in crustal boundaries have hindered the development of a reliable plate reconstruction of Southern Gondwana. By integrating seismic reflection, gravity, and magnetic data, an updated crustal architecture of the Falkland Plateau Basin is proposed, providing new insights into the tectonic evolution of the plateau and our understanding of such areas.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.
