Summary: The Cadomian magmatic rocks in the Istranca Massif range from peraluminous to slightly metaluminous, exhibiting calc-alkaline and high-K calc-alkaline compositions. Zircon U-Pb crystallization ages fall between 525.3 +/- 3.5 Ma and 548.7 +/- 2.3 Ma, indicating a subduction-related magmatic arc setting during the Late Precambrian-Early Palaeozoic period.

Summary: The study of the Zekeriyakoy Formation in Turkey revealed a diverse assemblage of foraminifera and rudist shells, suggesting a Late Campanian age for the formation. This indicates that Late Cretaceous volcanism in the Istanbul region ceased during or before the late Campanian period. The fauna in the formation shows similarities with those found in SW France and N Spain, suggesting an eastern extension of the European Faunal Province of the Tethys.

Summary: The eastern Tibetan Plateau is a region with unique topography and active tectonics, making it crucial for studying geodynamics and lithosphere-atmosphere interaction. By integrating new and reported thermochronological data, as well as paleo-crustal thickness reconstruction, this study sheds light on the tectonic deformation, climate-tectonic coupling, and geodynamics of the area.

Summary: This paper presents a modified method for calculating the lost gas content of shale by analyzing the coring and on-site desorption processes. The method accurately depicts the loss characteristics of free and adsorbed gas and identifies parameters that influence the calculation of in-situ shale gas content. The results demonstrate that the method shows satisfactory applicability in gas loss curve prediction and in-situ gas content estimation.

Summary: This study explores the factors contributing to sustainability in Pakistan from 1974 to 2018 and finds that emissions from industrial and agriculture sectors have significantly decreased, while the financial sector has not effectively reduced environmental pressure. Therefore, Pakistan needs to adjust its economic policies and ensure the green allocation of financial resources.

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 examines the impact of economic growth, financial development, eco-friendly ICT, renewable energy, and human capital on lowering carbon footprint in the world's top polluting economies from 1993 to 2020. The findings suggest that eco-friendly ICT has the potential to effectively alleviate pollution, and financial development, renewable energy, and environmental technology are proposed as potential solutions for reducing carbon emissions.

Summary: The study reveals the presence of water-fluxed melting during the Wuyi-Yunkai Orogeny in South China. These water-fluxed melting quartzo-feldspathic migmatites formed during the early Paleozoic and were melted through reactions involving water-saturated quartz, feldspar, biotite, and K-feldspar. The findings highlight the significance of water-fluxed anatexis in the differentiation of the continental crust during orogenesis.

Summary: Understanding the crustal growth, reworking, and geodynamics of the northern continental margin of Gondwana during the Ediacaran to Silurian times is crucial for the paleogeographic reconstruction of Gondwana. This study uses various analytical methods to evaluate the magmatic history of this region and obtain relevant detrital zircon data. The results provide valuable insights into the crustal evolution and tectonic activities in the northern Gondwana region.

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: A paleoclimate reconstruction based on high-resolution records from lacustrine shale in the Bohai Bay Basin reveals a shift in orbital variability and a humidification event at -41.9 Ma in East Asia. The intensification of the East Asian monsoons at this time was likely a response to the elevated atmospheric pCO2 during the concurrent global warming.

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.
