Summary: This study focuses on the Slagtersfontein outcrop complex in the Karoo Basin, South Africa, to analyze the features of channel-lobe transition zones (CLTZs) in Unit E of the Permian Fort Brown Formation. By integrating thin-section micrographs, sedimentary facies, bed-set and stratigraphic architecture, and palaeoflow directions, a novel process-based facies scheme is developed to identify bypass and depositional zones based on the distribution of sediment facies. The study also reveals the presence of seafloor erosion and a mega-scour within the CLTZ.

Summary: Distinctive plant fragment (PF)-concentrated sandstone beds are occasionally found in the turbiditic sequence of the Miocene Kawabata Formation in central Hokkaido, Japan. Sedimentological and organic geochemical analyses were conducted to investigate the transportation and deposition processes of the abundant PFs, revealing that terrigenous particles from specific terrestrial higher plants were effectively transported and deposited, leading to the formation of the PF-concentrated sandstone bed. The unique sedimentary structures observed in the sequences may be attributed to large flood discharge and the transportation of a huge volume of PFs directly from the upper reach of the river to the deep-sea basin by density flows.

Summary: This study investigates the floral diversity and palaeodepositional environment of the Lower Permian Rajhara sequence in the Damodar Basin. It reveals the presence of marine influence as well as the transition from fluvial to shallow marine conditions. The megafloral record suggests the presence of dense forest with swampy conditions and a warm and humid climate during deposition. The biomarker analysis indicates severe denudation under a warm/humid climate. The geochemical proxies suggest a freshwater-near-shore environment with possible marine influence due to fluctuating eustatic levels during the Permian.

Summary: This study presents a paleoecological analysis of the Hiraiso Formation in northeast Japan, revealing the temporal and spatial variations of diversity, ecological structure, and taxonomic composition in the Early Triassic marine ecosystems. The study suggests that the benthic fauna in the Hiraiso Formation represents an advanced stage of ecological recovery, but not full recovery. The distribution of the benthic fauna supports the habitable zone hypothesis and is consistent with oxygen gradients in modern environments.

Summary: Apatite in coal seams of the Late Permian in the Bowen Basin shows varied origins, including pore-apatites, fracture-apatites, detrital-apatites, and encrusting-apatites. Despite different modes of occurrence, the apatites analyzed in this study are predominantly fluorapatite, with minor variation in trace-element chemistry by mode of occurrence. Further investigation is needed to verify the geothermal source of apatite formation and isotopic composition analysis may provide important insights.

Summary: The patterns and mechanisms of organic matter (OM) enrichment in lacustrine deep-water shale successions are controlled by complex geological and biological processes. The integration of sedimentology, petrography, geochemistry, and sequence stratigraphy is crucial for accurate paleoenvironmental interpretations and the development of OM enrichment models. This study analyzes the geological responses caused by lake-level fluctuation in detrital input, sedimentation rate, benthic redox conditions, primary water column productivity, and OM enrichment pattern, based on a systematic analysis of three continuous cored wells in the Sichuan Basin. The results demonstrate that the correlation between proxies for detrital input, redox conditions, or productivity and total organic carbon content is not significant. The enrichment of OM is regulated by the interplay of these factors, which is influenced by relative lake-level fluctuation.

Summary: Paleomagnetic results for a magnetostratigraphic section of Permian rocks in the Karoo Basin of South Africa are reported. The study identifies titanomagnetite as the carrier of the recorded magnetization, which represents the Permian geomagnetic field during a reverse polarity superchron and subsequent mixed polarity interval. The timing of the magnetization is further constrained by Jurassic-aged dolerite intrusions. A paleopole is calculated based on the primary remanence, and the end of the Kiaman Reverse Polarity Superchron is correlated across the basin.

Summary: This study integrates high-resolution bathymetry, backscatter, and 2D and 3D seismic data to discern the controls on flow processes on the overbank areas of the Hikurangi Channel. Qualitative seismic interpretation and quantitative analyses of sediment wave morphologies and distributions indicate the importance of nine controls on flow and deposition. The study reveals the development of outer-bend wave fields on the landward margin and the increasing influence of centrifugal force on outer-bend overbanks, among other findings.

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: Phrases incorporating the modifier 'mark' have recently faced criticism. However, these phrases, such as bite mark and tooth mark, are widely used and align with the original definition of the word mark in scientific and other relevant literature. Therefore, using 'mark' as a modifier is appropriate and useful for interdisciplinary communication.

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 investigates an exhumed delta clinothem in the Magallanes Basin, Chile, to determine its stratigraphy and create a comprehensive organic carbon budget. The results show that over a period of 0.1-0.9 Myr, the clinothem buried a significant amount of terrestrial organic carbon, indicating that deltas have been and will continue to be important sinks for organic carbon over geologic timescales.

Summary: Previous research suggested that the terrestrial ability of bats is limited by pelvic and hindlimb morphology. However, this study found that the widespread North American bat species, Eptesicus fuscus, has greater terrestrial ability than non-vespertilionid bats of the same morphotype and is capable of lateral sequence walk. These findings reveal a wider range of terrestrial ability in type 2 bats than previously understood.

Summary: We discovered diverse forms of ancient granite rocky shoreline systems from the Early Miocene in northern Austria, and compare them with modern systems in the UK, Corsica, Spain, and Norway. Through stratigraphic and sedimentological analysis, we concluded that these rocky shorelines formed and were preserved during rapid tectonic and eustatic sea-level rise, along lithological, structural, and weathered weakness zones affected by normal low wave energy conditions interrupted by storms. These results provide a mechanism for predicting their potential occurrence and distribution during transgression of rocky coasts, with implications for exploration around structural highs and coastal management.

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.
