Summary: Recent study revealed a rapid increase of marine fauna species and genus richness during the Late Paleozoic Ice Age, lasting 41.2 million years and named as Carboniferous-earliest Permian Biodiversification Event (CPBE). The event included a slow increase episode and a main radiation episode, with most distinct patterns in fusulinid foraminifera and decreasing trends in nektonic conodonts and cephalopods, possibly related to marine environmental shifts caused by the Rheic Ocean closure.

Summary: The evolution of the western Tianshan Orogen was characterized by prolonged accretion and collision processes. The Late Carboniferous magmatism in the Awulale Mountains was likely a result of ongoing subduction, while the Early Permian magmatism may have been caused by post-collisional delamination of the lower crust and lithospheric mantle. This study provides important insights into the geological evolution and tectonic transition processes of the western Tianshan.

Summary: Paleosols provide valuable information about ancient landscapes, biotic interactions, and climate. They have played an important role in studying global climate changes and major extinctions, such as the end-Permian extinction. Recent research suggests that the extinctions in the marine and terrestrial realms during the end-Permian extinction were not synchronous, and there may have been no true mass extinction for plant and vertebrate communities on a global scale.

Summary: In the Rocky Mountain region of the western United States, upper Mississippian and Pennsylvanian stratigraphy in central Montana and northern Utah preserve a poorly documented, paleotropical stratigraphic record that spans the Carboniferous interval of the Late Paleozoic Ice Age (LPIA). Sedimentologic and stratigraphic investigation of these formations facilitated an appraisal of paleotropical environmental change and climate oscillations during this period. Through comparison with previously derived records throughout paleotropical Laurentia, it was found that the paleoclimate trends were influenced by factors such as plate migration and paleolatitude.

Summary: The southwestern margin of South America presents a comprehensive record of the Late Paleozoic Ice Age (LPIA) that affected the Gondwana supercontinent, refined into five discrete glacial events primarily occurring in marine environments. The paleofjord model has been confirmed in the Protoprecordillera with stages of valley incision, subglacial diamictite deposition, early and late transgressive events, and highstand with deltaic progradation. This glacial chronology reflects common tripartite motifs and is characterized by deglaciation sequences transitioning into postglacial conditions, demonstrating the complex interplay between glacial and marine processes in the region.

Summary: This study investigates the relationship between sedimentation in the retroarc Paganzo Basin and the magmatic arc activity in the Andean Cordillera during the Late Pennsylvanian-Cisuralian. By analyzing sedimentology, geochronology, and biostratigraphy, the researchers identified different sedimentary facies in the De La Cuesta Formation, indicating changes in paleoenvironments over time. The U-Pb age of 278.84 Ma obtained from the uppermost part of the formation supports a Kungurian age and correlates the sedimentation in the retroarc with the onset of Choiyoi Volcanism in the magmatic arc.

Summary: New XRD data, SEM analysis, and EDX microanalysis were conducted on clay minerals from Cretaceous-Cenozoic sedimentary sections in La Flecha and La Troya Sur creeks, Argentina. The characterization of clay mineral assemblages provides insights into paleoclimatic conditions, paleoenvironmental conditions, and the post-sedimentary history of these sedimentary depocenters. The mineralogical analyses reveal the presence of detrital and authigenic phases, including illite, smectite, illite/smectite mixed-layer clays, corrensite, chlorite, and kaolinite. The compositions of smectites suggest a combination of parent material and alkaline lake systems as controlling factors. The study emphasizes the importance of detailed clay mineral analyses in reconstructing sedimentary and post-sedimentary histories of basins near active tectonic areas.

Summary: Graphitic carbon nitride (g-C3N4) has been widely used due to its excellent optical properties and physicochemical stability. The risk of g-C3N4 transport in the environment has been overlooked, but this study investigated its transport behavior in various media. The results showed that flow rate and ionic strength influenced the transport, and the presence of lead (Pb) affected the outflow of g-C3N4. The unique structure of g-C3N4 particles allowed them to deposit in certain media and act as carriers for Pb release.

Summary: Magmatic-hydrothermal systems play a crucial role in transporting materials and potentially affecting Earth's long-term environment. This study investigates the duration of prograde metamorphism induced by fluid infiltration and the amount of carbon released by skarn ore deposits. The findings reveal that skarn ore deposits can efficiently decarbonize CO2 at a high rate, surpassing volcanism in different tectonic settings. The CO2 flux of skarn deposits increases over time and reaches a maximum value at the J/K boundary, providing an important previously unquantified source of outgassing in the subduction zone.

Summary: This study analyzes the U-Pb-Hf-O isotopes of zircons in felsic granulite xenoliths from the Fuxin late Cretaceous basalts in the North China Craton to evaluate the role of magma underplating in modifying the Archean lower crust. The results show that long-lived magma underplating occurred beneath the Fuxin region during the Mesozoic, with underplated magmas originating from the lithospheric mantle and later from the depleted asthenospheric mantle. This study concludes that magma underplating not only provided heat for remelting, but also added exotic material and weakened the lower crust, leading to its destruction.

Summary: This study investigates two volcanic provinces in the western branch of the East African Rift and finds that the volcanic products show wide variability in chemical and mineralogical characteristics. Petrographic and geochemical analysis reveals enriched and heterogeneous sub-lithospheric mantle sources. The differences in isotopic features between the two volcanic provinces may indicate changes in the composition, mineralogy, and depth of melting in the lithospheric mantle source.
