Summary: This study documents a large-scale, composite erosion surface from the exhumed deep-marine stratigraphy of Unit 5 from the Permian Karoo Basin succession in South Africa. The study utilizes sedimentary logs, cored boreholes, and extensive data to identify lower heterolithic-dominated and upper sandstone-dominated parts separated by an erosion surface. The findings provide insights into the formation and evolution of submarine channels and the transition from erosion-dominated flows to depositional flows in deep-marine systems.

Summary: The study focuses on the importance of trees in pastures and proposes a methodology that integrates field and UAS surveys to study tree characteristics. The results show that UAS surveys can provide reliable estimates of tree height, crown diameter, and tree density, which have a direct impact on biomass estimates. Additionally, UAS surveys cover larger areas and are more cost-effective compared to field methods only.

Summary: Observations from the modern seafloor have led to investigations into sediment gravity flow behavior at the mouth of submarine channels. These investigations have revealed various types of channel mouth configurations, including traditional channel-lobe transition zones, plunge pools, and channel mouth expansion zones. Understanding the morphodynamic differences between these configurations requires a review of physical experiments, field observations, and numerical modeling. Additionally, the identification of the stratigraphic record of channel mouth settings is complicated by the propagation and avulsion of channels.

Summary: This article discusses the issues of reproducibility and replicability (R&R) in geospatial unmanned aircraft systems (UAS) workflows. Key barriers include awareness of time and resource requirements, accessibility of provenance, metadata, and version control, conceptualization of geographic problems, and geographic variability between study areas. Facilitating R&R in geospatial UAS applications can be achieved through providing provenance information and establishing R&R as an important aspect of UAS and related research design.

Summary: This study focuses on the characteristics of thin-bedded turbidites in submarine fan deposits, highlighting the frequent lateral facies changes and rapid thickness changes in thin sand beds compared to conceptual models. Additionally, the research finds that a single measure of lateral heterogeneity does not accurately reflect the true architecture of sandstone beds.

Summary: This study successfully distinguishes the contributions of turbidity currents and mass transport, as well as their seismic expressions, through strategic forward modeling and seismic forward modeling. The results show that mass transport plays a major role in canyon initiation, while turbidity currents primarily act as the reworking process. Additionally, the study identifies different synthetic seismic facies and verifies them with actual seismic data.

Summary: This paper investigates the geomorphological evolution of a segment of the Blanco Este River in southern Chile, focusing on the disturbances caused by the eruptions in 1961 and 2015. The study reconstructs the geomorphological changes using photointerpretation and image analysis, and analyzes the evolution of geomorphological units and processes. The study also examines the vegetation recovery using the NDVI and characterizes the fluvial corridor using braiding indices and active channel widths. The findings show similar evolutionary trajectories after the 1961 and 2015 eruptions, with major adjustments occurring in the first period of observation after the 1961 eruption, followed by gradual relaxation and regeneration of vegetation cover. The 2015 eruption reset the fluvial landform and initiated a new cycle of sedimentation and braiding.

Summary: The Messina Strait in southern Italy is a tide-dominated marine passageway with steep subaqueous zones incised by canyons and gullies. This study focuses on a Lower Pleistocene coarse-grained succession exposed along the northeast margin of the strait, highlighting the presence of a subaqueous delta complex entering submerged canyon heads. Tidal-influenced sedimentation dominated over fluvial-influenced processes during the late transgression, overfilling the canyon relief and preserving large supercritical-flow sedimentary structures.

Summary: Monitoring of modern deep-water channels has shown how migrating channel-floor features create and remove stratigraphy, improving understanding of channel morphologies and their deposits. Integrated study of high-resolution bathymetry and seismic data imaging a trench-axial channel in New Zealand revealed terraced channel-walls, flat channel-floors, and specific features like cyclic-steps and knickpoints. Subsurface analysis identified depositional elements like channel-fill and mass-transport deposits, showing the localized response to mass-transport deposit emplacement through knickpoint-zone migration in the Hikurangi Channel.

Summary: The Miocene Serra Palazzo Formation was deposited in a foredeep basin in front of the Southern Apennines orogenic wedge. The deposition history can be divided into two phases, with tectonics playing a significant role in controlling the stacking patterns of submarine fans in the basin. This study highlights the influence of basin topography and outward thrust migration on the sedimentary features and evolution of the SPF basin.

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.

Summary: This study employs an integrated depositional and sequence stratigraphic approach to assess the control of diagenesis on reservoir porosity of a hybrid-energy delta system. The study focuses on the Barik Formation in the Haushi-Huqf region of Central Oman, which represents a highstand system tract of a hybrid-energy delta. The assessments reveal that the reservoir porosity is controlled by various degrees of diagenetic processes, including mechanically infiltrated clays and kaolinitization of silicate grains.

This study investigates the metallogenic characteristics and enrichment process of oilfield brines from the Jianghan Basin, central China using chemical and multi-isotope data. The results suggest that lithium enrichment in these brines is the result of interaction with clastic host rocks and dilution by meteoric water.

Summary: Due to the lack of deep wells in the broader region, studying mud volcanic deposits can improve the geological understanding of the Mediterranean Ridge. In this study, biostratigraphic and geochemical analyses were performed on mud breccia deposits from five Mud Volcanoes in the central MR. The results indicate the origin of these deposits and provide insights into the source rock potential. Seismic data is also used to determine the distribution of major lithostratigraphic formations.
