Summary: This study integrates various geological data to investigate the thermo-rheological structure of the Qiongdongnan Basin (QDNB) and Pearl River Mouth Basin (PRMB), focusing on the variation of the passive continental margin rifting from west to east. The research reveals that the current architecture of the continental margin is the result of non-uniform extension, with the rupture of the mantle lithosphere preceding the crust due to the decoupled crust-mantle relationship. The presence of high-velocity layers (HVLs) and detachment faults beneath the Xisha Trough and the eastern PRMB are attributed to the cooling of a thinned lower crust with mantle underplating during different stages of continental margin rifting. A seaward-increasing trend of lithospheric rheological strength is observed across the PRMB.

Summary: There is a large silicic igneous province in SE South China, and different models have been proposed to explain its origins. New data on zircon from wells in East China Sea, along with tectonomagmatic comparisons, allow for a reassessment of the geodynamic interactions between the Cathaysia-based arc and intraplate activity. Changes in arc magmatic states permit identification of a cycle of arc initiation, thickening, decline, arc-root removal, and arc migration, highly correlating with changes of subduction beneath East Asia. Voluminous intraplate silicic magmatism operated in response to slab dehydration, lithospheric delamination, fluid-fluxed crustal anataxis, and crustal-mantle melt hybridization.

Summary: By restoring the topography of the Messinian Nile canyon and the vertical position of the Messinian coastline, we estimate the amplitude of the sea-level drop during the Messinian salinity crisis. Our findings suggest that the drop was smaller than previously thought and had a significant impact on the Mediterranean continental margins.

Summary: Provenance analysis using Pb isotopes in detrital K-feldspars successfully tracked first-cycle sand supply in the Scotian Basin, revealing a dynamic see-saw effect between hinterland sources across the Jurassic-Cretaceous boundary. The data also showed progressively increasing long-distance supply from eastern Labrador alongside diminishing local sourcing from adjacent Appalachian terranes. This case study highlights the limitations of using a single mineral proxy and the potential of multiproxy provenance toolkits in deciphering sediment-routing corridors and understanding Earth surface processes and tectonic events.

Summary: Through the analysis of onshore cores, we have gained a deeper understanding of the stratigraphic architecture and sedimentary response of late Quaternary paleovalley systems. These systems experienced erosion during the late Pleistocene, filling during the Holocene, and basinwide flooding. The sediment characteristics indicate a shift in sediment provenance from southern Apennine rocks to a mixed composition from northern sources, due to the influence of the Southeast-directed Western Adriatic Current.

Summary: Rifted continental margins, like the Brazilian South Atlantic margin, have substantial morphological variations and differ in their denudation patterns. This study focuses on the continental margin of southeast Brazil and finds that it has distinct regions with different denudation patterns, influenced by both the South Atlantic rifting and post-rift exhumation triggered by inherited basement structures. The morphological differences between different segments of the margin suggest that it is not a single continuous tectonic setting.

Summary: The study reveals that in rapidly subsiding basins, aeolian successions are thicker with more extensive dune-sets and wet interdunes, while in slowly subsiding basins, aeolian successions are thinner with predominance of sandsheets and deflation surfaces. The rate of basin subsidence affects the sedimentary stratal architecture and preservation of aeolian successions.

Summary: The terrestrial sedimentary record provides important information about how ancient depositional systems responded to and recorded changes in Earth's atmosphere, biosphere, and geosphere. However, the understanding and quantification of environmental changes in eolian sedimentary successions are limited. This study presents the first global-scale investigation of eolian system architecture through analysis of 55 case studies. The results show that eolian deposits under different conditions have different architectural elements and thicknesses. Pre-vegetation eolian systems also have more frequent interactions with non-eolian environments. These findings shed light on the complex interplay of various factors in eolian sedimentary deposition and provide insights into major environmental changes in Earth's history.

Summary: A database-informed metastudy of 294 globally distributed submarine canyons has shown that the tectonic setting does not significantly affect the geomorphology of these canyons. However, there are scaling relationships between certain aspects of canyon geomorphology and attributes of the source-to-sink system and environmental setting, which can differ between active and passive margins.

Summary: The avulsion frequency of coastal-plain rivers is primarily controlled by the elevation difference between channels and neighboring plains, as well as multiple factors such as wave and tidal processes, rates of sea-level change, and bathymetry of the receiving basin. This study analyzes the relationship between these downstream factors and avulsion frequency in 57 Holocene lowland river systems, finding that wave and tidal processes may have a modest influence and there is no consistent relationship with offshore bathymetric gradient or sea-level fluctuations. This suggests that upstream or intrabasinal factors may play a more important role.

Summary: This study quantitatively compares globally distributed aeolian successions from the Precambrian and the Phanerozoic and finds that Precambrian aeolian successions are characterized by thinner aeolian dune sets and a greater occurrence of sandsheet, zibar, and damp and wet interdune deposits. The absence of sediment-stabilizing terrestrial vegetation, stronger wind forces, and more humid climates contribute to these differences. This study provides new insights into the controlling factors of aeolian sedimentation during the Precambrian.

Summary: The coefficient of variation of preserved dune cross-set thickness may not be a good predictor of discharge variability. Larger rivers are more prone to disequilibrium, but smaller CV(Dst) values are not necessarily associated with conditions favoring dune disequilibrium. Only about 25% of the studied examples align with quantitative formulations of variability-dominated preservation. This suggests that the multiplicity of factors controlling dune preservation may result in poor prediction based on cross-set thickness variability.
