Summary: Geologists have found that the formation of past three supercontinents were preceded by a megacontinent similar to Gondwana, and this assembly of a megacontinent is considered a crucial precursor to supercontinent amalgamation. The recent assembly of Eurasia is seen as the fourth megacontinent associated with the future supercontinent Amasia.

Summary: This study refines the paleoenvironmental reconstructions of Late Cretaceous rivers through facies and facies associations analysis, meander-belt architecture characterization, and paleohydraulic parameter calculations. The results demonstrate that the meander-belt deposits of the Dinosaur Park Formation were deposited in a fluvial environment upstream of the fluvial-marine transition zone, changing our understanding of the paleogeography of the Western Interior Seaway in western Canada. This study contributes to the validation and development of a systematic approach to the paleoenvironmental reconstruction of ancient river systems based on paleohydraulic analysis.

Summary: Palynomorph assemblages and palynofacies analyses were conducted on core samples from Devonian-Carboniferous deposits in the eastern region of the Moesian Platform. Seven biozone intervals were recognized based on the stratigraphic distribution of key taxa. The depositional environment transitioned from distal to proximal/fluvio-deltaic conditions from the Lochkovian to Pragian times. The Early Devonian samples were dominated by trilete spores of lowland vegetation, while Carboniferous samples consisted of miospores of arborescent and herbaceous lycopsids and ferns.

Summary: Despite the long history of the symbiotic relationship between epibiotic turtle barnacles and marine turtles, there have been few studies on the ancient origins of this association. This study presents evidence of platylepadid attachment scars on a Miocene turtle carapace, suggesting that this symbiotic relationship may have existed as early as the Oligocene period and became widespread during the Miocene epoch. Further research on bone modifications in fossil turtle remains is expected to contribute significantly to the emerging field of palaeosymbiology.

Summary: Late Ediacaran to early Cambrian is a key period for the formation of barite deposits in cherts and shales. The paleoenvironment evolution and source of ore-forming materials during this interval are still controversial. In this study, geochemical research on Gongxi-Tianzhu barite deposits was conducted, revealing that the bottom water was oxygen-depleted during the depositional time. The barite deposits were formed in the Sulfate-Methane Transition Zone due to redox state variations and barium remobilization.

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 investigates the seismic structure of the Eastern European lithosphere and the transition from Precambrian to Phanerozoic Europe. The results show that the crust thickens across the Trans European Suture Zone boundary and the mantle is seismically faster beneath younger terranes. The Precambrian building blocks exhibit contrasting seismic fabrics, with the Baltic orogens characterized by uniform crust and the Sarmatia region showing alternating high and low velocity layers.

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.
