Summary: Open-cast lignite mining in the Lusatian region of Germany has led to the input of pollutants such as iron, sulphate, trace metals, and aluminium into groundwater and rivers, affecting sediment compositions along the River Spree in urban Berlin. The study found that nickel, cobalt, and sulphur elements showed a significant impact downstream of the mining area, while sulphur and iron exhibited different transport mechanisms. The mining signature in urban Berlin has been replaced by an urban signature characterised by high levels of zinc, chromium, lead, and copper.

Summary: This study examines the cause of fine-grained sedimentation in the Neogene saline lacustrine Qaidam Basin and proposes that winter storms related to Asian winter winds are the main cause for the formation of fine-grained sediments.

Summary: This study utilized a multidisciplinary approach to characterize sediments from the archaeological site Vina - Belo Brdo, Serbia, shedding light on paleoenvironmental conditions during Pleistocene and Early Holocene sedimentation and their impact on human-environment interaction during the Neolithic. Organic geochemical characterization, combined with other analyses, provided insight into the depositional environments, mineralogy, and organic matter origin within the sediment samples, revealing the complexities of ancient civilizations settling in the region.

Summary: This study investigated the transport and deposition of phosphorus in the Yellow River basin, finding that medium grain size plays a crucial role in influencing phosphorus and its fractions. The analysis also showed that different oxides have significant impacts on the adsorption of NaOH-P in sediments. Furthermore, the vertical pollution status in sediment cores becomes more severe with increasing silt content.

Summary: The study reveals that during the last glacial period, intensified wind and freeze-thaw action of ice actively weathered the high elevation western catchment, leading to persistent perennial lake ice-cover, anoxia, low sedimentation, weak brackish conditions. As deglacial conditions augmented around 18.8 cal. kyr BP, increased catchment meltwater flow enhanced sediment transport and transformed the lake into a freshwater basin, although perennial ice-cover still prevailed.

Summary: Predicting the post-failure evolution of underwater mass movements is crucial for assessing the risk of offshore structures and ensuring the safety of coastal communities threatened by tsunamis. This study investigates the contribution of various geometrical parameters, such as slope inclination and thickness of frontal basin sediments, using a coupled Eulerian-Lagrangian finite element framework. The strength difference between the slope and frontal basin sediments is found to play an important role in determining the post-failure geometry.

Summary: This study analyzed the geochemical characteristics and sources of natural gas in the western Qaidam Basin using isotopes and gas composition. The natural gas in this region consists mainly of hydrocarbon gases, with high dryness coefficient, heavy carbon isotopes, and high thermal maturity. The main gas source rocks in the western Qaidam Basin are identified as lower Ganchaigou (E-3), upper Ganchaigou (N-1), and lower Youshashan formations (N-2(1)).

Summary: This study discovered shale oil resources in the Lower Member of Paleogene Xingouzui Formation (LXF) of the Jianghan Basin and investigated the mechanisms of organic matter enrichment. Different sedimentary environments were found to control the source and enrichment of organic matter.

Summary: Thick Pleistocene fine-grained rocks in the central Qaidam Basin are the principal source rocks for microbial gas, with two different lacustrine source rock facies present. Organic facies A developed under suboxic to anoxic freshwater conditions with high petroleum generation potential, while organic facies B deposited in more oxic, brackish-lacustrine conditions with lower petroleum generation potential. Algae mats sealed sediments under anoxic conditions, contributing to gas prone kerogen mainly derived from aquatic plants.

Summary: The study investigated particle size distribution and heavy metal concentrations in surface sediments of streams and lakes in the Seomjin River Basin by comparing with Sediment Quality Guidelines (SQGs). Different origins were identified through statistical and geochemical approaches. The results showed that while some heavy metal concentrations were higher in the Boseong River, overall pollution levels in the basin were not severe.

Summary: This study investigated the geochemical dynamics of sediment organic matter in mangrove wetlands and found significant exchanges of mangrove OM with marine and mixed forest OM. Despite these exchanges, distinct values of delta C-13, TOC and C/N were observed in modern surface sediments of different vegetational zones, confirming their usefulness as coastal environmental proxies. The proxies, combined with chronologies based on radiocarbon, 210 Pb and 137 Cs analyses, were successfully used to reconstruct the depositional history of the mangrove wetland, providing new insights into environmental responses to natural and anthropogenic drivers.

Summary: Mineralogical investigations on sediments in the Yellow River Basin were conducted to understand the mineral distribution mechanism and environmental significance. The results revealed cold and arid climate conditions with weak hydrolysis and strong erosion accelerating physical weathering. Different minerals were found in different reaches of the river, with clay minerals primarily originating from the Tibetan Plateau and quartz and feldspar possibly deriving from the source area and upper reaches.

Summary: The Neogene Miyazaki Group in Southwest Japan exhibits significant spatial variations in consolidation despite minor differences in depositional ages. The study found that the reduction in porosity associated with consolidation is a more important control on lithification than the depositional age or maximum temperature. Additionally, the research identified variations in sedimentary depositional environments within the Miyazaki Group, with higher consolidation observed in the shallower marine facies.
