Summary: Our integrated geological and geophysical study of the Faroe Platform revealed two new sedimentary basins-the Beinta and Kerstin basins, bounded by four basement highs-the West Suouroy High, East Suouroy High, Borooy High, and the Sandoy High. The basins extend to depths of 8-10 km and 8-9 km, respectively, while the tops of the structural highs are located between 3-6 km below the present-day surface. The study also showed evidence of Miocene-Pliocene basin inversion and cross-cutting intrusive networks in the central part of the Faroe Platform, likely part of the magmatic plumbing system.

Summary: This study investigates the geochronology, mineralogy, and geochemistry of four tonstein samples from the Permo-Carboniferous Benxi Formation, Ordos Basin, North China Craton. The results show that these tonsteins have features of pyroclastic and felsic magma origin, providing precise chronological information and affecting the distribution of elements in coal seams.

Summary: This study aims to identify whether natural or man-caused factors have a dominant impact on the variable groundwater salinity of the Lower Jurassic sediments in the Talinskoye oilfield of West Siberia in Russia. The findings suggest that the major factors affecting the variability in groundwater salinity are natural ones, as evidenced by the genetic coefficients and the tight associations with geological parameters.

Summary: The study reveals Permo-Carboniferous provenance shifts at the northern margin of the North China Craton, with sediment contributions from the Southern Orogenic Belt shifting to the North China Craton during the Permian-Carboniferous transition.

Summary: Based on seismic profiles and geological data, the formation of the North Luzon Forearc Basin is explained using a strike-slip pull-apart basin model. The study identifies four tectonic evolutionary stages and proposes an indentation-escape process for the evolution of the eastern South China Sea Basin margin.

Summary: Comparison of CIA values and LSTs between North China and Gondwana Basins during the late Paleozoic Ice Age reveals four cooling events, with two severe events around 300 Ma and 287 Ma and two less-pronounced events at 297.5 Ma and 295 Ma. Decreased chemical weathering intensity in North China and glaciations in Gondwana Basins, along with stepwise decreases in pCO2, suggest that CO2-forced climate change played a significant role. Tectonism, atmospheric and ocean circulation, and orbital parameters also contributed to glaciations and deglaciations.

Summary: The Maloy Slope in South Norway has been a key area for studying the connection between onshore and offshore geology since the Permian period. It has experienced bypass, erosion, and deposition processes between the Norwegian mainland source area and the offshore northern North Sea sink area. The slope was faulted during large-scale extension and rapid rift basin subsidence in the Late Jurassic and Early Cretaceous, forming a network of E-W-oriented erosional submarine canyons that cut deep into the crystalline bedrock.
