Summary: The Oaxacan Complex Carboniferous-Permian sedimentary cover in southern Mexico records provenance shifts through time, reflecting the collision between Gondwana and Laurentia to amalgamate Pangea. The integration of petrological analysis and LA-ICP-MS U-Pb zircon geochronology suggests that the sedimentary units were deposited in a peri-arc basin, sharing sediment provenance with adjacent terranes. The presence of volcanic activity and detrital zircon grains from different ages indicate the formation of magmatic arcs associated with subduction events.

Summary: The Baoshan, Tengchong, Lhasa, South Qiangtang, and Sibumasu terranes were part of Gondwana before separating and moving away from the northern margin in the Early Permian. The paleopositions of these terranes during the late Paleozoic are still debated, which hampers the understanding of the tectonic evolution of the PaleoTethys and glacier distribution patterns on eastern Gondwana during the late Paleozoic ice age. Through analysis of detrital zircon U-Pb dating and Hf isotope signatures, this study proposes a new paleogeographic model that suggests the South Qiangtang, Baoshan, and part of Sibumasu were located outside the northern margin of Indian Gondwana, while the Lhasa and Sumatra terranes were along the northern margin of Australia. Based on shifts in provenance of late Paleozoic glaciogenic sedimentary rocks, the study also hypothesizes the development of two main ice sheets during the late Paleozoic. This research contributes to the understanding of the late Paleozoic tectonic and paleoclimatic history of Gondwana.

Summary: This study investigates the sedimentary rocks of the early Paleozoic Lancang Group in the western Yunnan Tethyan orogenic belt, SW China. The results indicate a significant change in sediment provenance from the lower to the upper sequences of the Lancang Group, with similarities to exposed rocks in North India. This suggests that the Lancang Block was adjacent to the northern margin of Gondwana during the early Paleozoic. The sediment provenance change might have resulted from the subduction of Proto-Tethys in the late Ordovician.

Summary: The detrital U-Pb age peaks and Lu-Hf systematics of peri-Gondwanan units in southern Turkey suggest their derivation from Neoproterozoic igneous suites in the Sinai Peninsula, Israel, and the Eastern Desert. These sediments were likely derived from sedimentary recycling processes in a continental back-arc tectonic setting. The provenance of the sediments correlates with nearby regions such as the Nubian Shield and Saharan Metacraton.

Summary: Studies of Paleozoic sedimentary rocks in the Fort Worth Basin show changes in sandstone composition from the Cambrian to the Permian, indicating increased input from a recycled orogen and a change in provenance likely linked to Gondwana. This is supported by new provenance data which suggest erosion by transverse rivers linking the high Ouachita hinterland and foreland as Laurentia and Gondwana collided to the east of the basin.

Summary: The basal Cambrian sandstone unit in the North China craton provides insights into the ancient drainage system and its potential linkage with the Gondwana landmass. The detrital zircon age signatures in different sections of the craton show spatial changes and can be categorized into three distinct types, suggesting that the basal Cambrian unit is not part of the sand sheet across the northern margin of Gondwana.

Summary: This study focuses on the formational controls of early Cretaceous syn-rift quartzose in northern Gondwana, indicating a predominant plutonic provenance for the quartz-rich sandstones with the possibility of significant sediment reworking being ruled out based on short to moderate transport distance. The humid paleoclimate and associated rigorous chemical weathering are identified as the dominant controls in the formation of the quartzose sandstone.

Summary: Devonian-Carboniferous strata in the Hida Gaien belt, Southwest Japan, undergo lithological changes from clastic rocks and limestones to volcanic rocks. The sedimentary rocks during the Devonian period were derived from various basement rocks and the source shifted to basalts and rhyolites in the early Carboniferous period. Zircon grains indicate sediment supply from different areas in Eastern Asia and NE Gondwana. The Hida Gaien belt and other regions were geographically close to NE Gondwana during the Paleozoic era.

Summary: The Ossa-Morena Complex in the SW Iberian Massif contains a stack of units with different origins, including a Cadomian ophiolite, the Merida Ophiolite. The Cadomian terranes in this complex are important for reconstructing the Ediacaran margin of Gondwana in NW Africa. The Merida Ophiolite represents oceanic lithosphere of a back-arc basin and played a role in the collision between the volcanic arc and the Gondwana margin.

Summary: By analyzing the detrital zircon and rutile from the early Paleozoic Lalun Formation in Iran, it was found that most of the detrital sediments originated from the Neoproterozoic age, and the Arabian-Nubian Shield may be a more suitable source for the formation. This study reveals a complex pattern of sediment dispersal along the northern margin of Gondwana and challenges the idea of a well-mixed, far-travelled sand sheet.

Summary: The Serre Batholith in Central Calabria represents the intermediate portion of late Variscan continental crust, with upper levels composed of two-mica granodiorites and granites, and lower levels of weakly peraluminous granodiorites. The granitoid rocks in the batholith exhibit deformation microstructures due to tectonic stresses, with a magnetic foliation showing a shortening axis oriented NW-SE. Ongoing studies aim to further investigate the relationship between regional tectonic structures and the emplacement of the late-Variscan Serre Batholith granitoids.

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.
