Summary: The fluvial-aeolian interaction environment in the Guandacol valley in northwest Argentina was studied using various methods, identifying several depositional subenvironments and architectural elements, serving as a potential analogue for studying ancient fluvial-aeolian interaction environments.

Summary: Interdune deposits in the ancient desert system of southern Africa provide insights into the dynamics of desert environments over time. This study focuses on the Clarens Formation and identifies different facies associations, indicating variations in sediment availability and climate. The findings reveal the presence of meso-scale and macro-scale lakes within the dune system, with different mechanisms of flooding and sediment deposition.

Summary: In semi-arid basins, the geomorphic evolution is influenced by interactions between fluvial erosion, aeolian erosion, and the presence of erosion-resistant basement outcrops. The occurrence of non-erodible basement in deflation zones complicates drainage systems and wind-flow patterns, leading to rapid topographic modifications over time.

Summary: This study analyzed the elemental geochemical properties of sediment profiles in Hudong Sandy Land and compared them with modern basin sediments and Late Quaternary aeolian deposits. It was found that the sediments in Hudong Sandy Land have similar compositions to modern basin sediments and exhibit distinct characteristics from lacustrine sediments. The findings provide insights into the interaction between the East Asia summer monsoon and East Asia winter monsoon/westerlies.

Summary: The E-W oriented Sivas foreland basin in Turkey experienced a salinity crisis during the Late Eocene, leading to thick evaporite accumulations and intense halokinesis during the Oligo-Miocene period. The transition from marine deposits to evaporitic facies across sedimentological sections reveals different sedimentary features in various parts of the basin, reflecting the progressive transition from marine to continental environments.

Summary: The study synthesized data from the post early Eocene foreland basin succession in Svalbard to generate an updated depositional model, revealing a foredeep setting governed by flexural loading with high sedimentation rates and uncommon relative sea-level falls. The basin fill had a bipartite structure with shelf and shelf-edge deltas, clinothems, and fans, suggesting a wedge top basin in the mature stage. Time-equivalent deposits were found in other regions, indicating potential southerly diversion of sediment-routing.

Summary: The Eocene-Oligocene transition had a significant impact on the stratigraphic evolution of submarine fans, as indicated by sedimentary and stable isotope data from the Alpine foreland basin.

Summary: This study used EMMA, MDS, and PCA to identify sedimentary characteristics, provenance, and transport of sediments in the Yellow River Basin and analyze aeolian-fluvial interactions. Sediments in the source area came from the Tibetan Plateau, while those in the lower reaches came from the Chinese Loess Plateau (CLP). Sediment transport was controlled by simultaneous or alternating aeolian and fluvial processes. The study has implications for paleoclimatic reconstruction and soil and water conservation.

Summary: This study examines the temporal and spatial relationships between fluvio-aeolian, aeolian, and volcanic systems in the southernmost part of the Parana Basin during the Late Jurassic and Early Cretaceous. By analyzing facies and architectural elements, the evolution of the volcano-sedimentary record is reconstructed.

Summary: Fluvial fans are important sedimentary systems at active margins of non-marine foreland basins. The Puig-reig anticline in Spain exposes Late Eocene-Early Oligocene fluvial deposits, categorized into proximal, medial, and distal deposits. These deposits show varied sedimentary characteristics, influenced by diagenesis and deformation processes.

Summary: An analysis of the sedimentary fill of a foreland basin in Utah, USA shows that fluvial planform and architecture remained constant across different geographic locations and stratigraphic positions during the flooding of the Western Interior Seaway in the mid-Cretaceous, regardless of base-level rise or changing climate conditions.

Summary: In this study, a high-resolution astronomical time scale spanning the middle to late Eocene was established using magnetostratigraphy and cyclostratigraphy. The results showed that hydroclimate variability in the Weihe Basin during this period was mainly controlled by eccentricity and obliquity forcing. The findings provide new insights into the driving mechanisms of orbital-scale hydroclimate evolution during the ice-free middle to late Eocene in continental lake basins.

Summary: By measuring fluid inclusions in halite samples from the Qianjiang Formation in the Jianghan Basin, it was found that the temperature fluctuations in the middle Eocene were similar to those in Death Valley, indicating the presence of a monsoon climate during that time.

Summary: Histories of vertical lithospheric motions provide important clues about geodynamic processes. We present evidence of an ancient landscape that likely uplifted and subsided rapidly during the incipience of the Icelandic plume. This landscape contains meandering fluvial channels and exhibits three phases of uplift, similar to other landscapes in the nearby Judd and Bressay areas.

Summary: The study of the Baluti Formation in northern Iraq reveals the geological characteristics and depositional environment of the Late Triassic period, with a focus on the composition of limestone and clastic rocks and the climatic conditions. The abundant components and trace element contents indicate different depositional environments, reflecting the hot, arid climate and marine oxidation conditions at that time.
