Summary: This study presents palaeobotanical investigation results of the lignite deposit in Ruja, focusing on vegetation characteristics and climate change during the middle Miocene period. The findings reveal a wetland vegetation dominated by mesophytic forests with a warm and humid climate, transitioning to a warm temperate climate in later stages. The results correspond with current understanding of climate change in the middle Miocene in Europe.

Summary: This study shows that despite being below seismic resolution, small-scale sand injectites can be detected in seismic data. The detection is more likely if the injectites have high thickness, steep dip, and dense spacing. The presence of sand injectites also decreases the top reservoir amplitude. Comparisons between synthetic seismic images and real data indicate that low-amplitude anomalies observed above the reservoir may be caused by overlying sand injectites. Additionally, the study suggests that the Grane Field hosts thicker and more distant sand injectites than what well observations indicate.

Summary: This paper presents a detailed description of the sedimentary characteristics and architecture model of a tidal-dominated estuary reservoir in the Lower Cretaceous McMurray formation. The study identifies 13 lithofacies and classifies them into nine types of architecture elements. Through the combination of seismic data and well data, the architecture model and stacking patterns of the reservoir are established. The study reveals the importance of tidal bars and sand flats as the best reservoirs and provides insights for future research in estuarine sedimentary patterns and reservoir architecture.

Summary: Humans are major geomorphological agents in modern times, with activities like open pit mining significantly altering landscapes. Analyzing historical maps and modern data comparisons can reveal the impact of human activities on geomorphology, aiding in understanding the dimension of humans as geomorphological agents.

Summary: This study analyzed the distribution characteristics and vertical profile characteristics of suspended sediment concentration (SSC) in the Yangtze River Estuary and its adjacent waters under different tidal current states. It verified the applicability of the Rouse and Soulsby models in the study area and provided theoretical basis for marine forecasting, analysis, and evaluation. The study is important for scientific research and management of mudflat resources.

Summary: The study found that the reduction efficiency of PM0.4 by calcined kaolin during Zhundong lignite combustion is related to the Si-Al compound content, with chemical adsorption contributing the most to PM0.4 reduction. Additionally, the PM0.4 reduction efficiency is proportional to the furnace temperature in the range from 900 degrees C to 1300 degrees C.

Summary: Coal and biomass-fired power plants have significant impact on particulate matter emissions. This study measured ultrafine PM size distributions and used CFD simulations to evaluate the conversion behavior of different solid fuel particles. The data provide an important basis for further research.

Summary: A Desmostylus tooth from the earliest Miocene (Aquitanian) Skooner Gulch Formation in northern California, USA is reported here. This specimen exhibits both primitive and diagnostic features different from other desmostylid genera, suggesting that Desmostylus has persisted with its distinctive tooth morphology largely unchanged for over 15 million years and possibly originated in western North America.

Summary: The N losses and agronomic performances of newly developed slow-releasing fertilisers (SRFs; Epox5 and Poly5) were compared with conventional N fertilisers (urea and DAP) in a climate-controlled lysimeter system. Results showed that the dry matter yield and N losses of SRFs were not significantly different from urea and DAP. However, nitrate leaching and nitrous oxide (N2O) losses were unexpectedly low, indicating a chemical transformation of nitrate. The involvement of iron-rich sand in nitrate reduction under anaerobic conditions was hypothesised.

Summary: Estuarine degradation is a global concern, and this study focuses on the highly modified Guadiaro estuary in Spain. By utilizing the Sentinel-2 satellites and the GEE platform, the study monitors the estuary for a 4-year period. The results indicate a closure trend of the estuary mouth and the absence of clear seasonal patterns. This study highlights the potential of Sentinel-2 and GEE for estuarine monitoring and its contribution to coastal and ecosystem-based management.

Summary: The research found that sand cover treatment changed the runoff generation mechanism from infiltration-excess runoff to subsurface saturation-excess runoff, delaying runoff initiation and increasing runoff volumes and soil loss compared to the control. Rill erosion on sand-covered slopes was dominated by shallow and wider rills, while on loess slopes it was dominated by narrow and deeper rills. The presence of a sand layer over less pervious loess soil promoted return flow and accelerated rill formation and development.

Summary: Due to the dual effects of fluvial and tides, tidal sand bars in estuaries have complex sedimentary characteristics and structures. This study used a sedimentary dynamics numerical simulation method to establish a tidal-controlled estuary model and analyzed the effects of tidal range and sediment grain size on tidal sand bars. The results showed that tidal range had a more significant effect on tidal sand bars compared to sediment grain size, affecting their length-to-width ratio and degree of development. The formation and distribution of shale layers in tidal-controlled estuaries were also influenced by tides.
