Summary: The sandstone-hosted uranium deposits in the SW Songliao Basin have different geological features compared to typical sandstone-hosted uranium deposits. Studies on the Upper Cretaceous Yaojia Formation, the uranium-bearing layer, were conducted using various analytical techniques to investigate the role of hydrothermal fluids in the formation of these deposits. The results showed the presence of kaolinite alteration and hydrothermal fluids with medium-low temperature and high salinity. Three types of hydrothermal fluids, including acid fluid, groundwater heated by mafic magma, and alkaline fluid rich in Ca2+ and CO32-, were identified. These fluids played successive roles in the formation of the uranium deposits, with kaolinite absorbing uranium, thermal energy changing the redox environment, and alkaline fluid facilitating the formation of soluble uranium complexes and the precipitation of uranium minerals.

Summary: Understanding the anisotropy of thermal conductivity in rocks is crucial for the development of geothermal reservoirs. The study found that rocks with a high proportion of layered minerals generally exhibit anisotropic thermal conductivity, while the anisotropy in syenogranite, rhyolite, and mudstone in the Songliao basin is not significant. Granodiorite and sandstone were observed to have anisotropic thermal conductivity, with average anisotropy factors of 1.12 and 0.89, respectively.

Summary: Free hydrogen detected in the Songke-2 well in the Songliao Basin, China has a strong crustal contribution. Molecular hydrogen is generated after late hydrocarbon gas generation is complete. While storage in organic matrices is unlikely in this depositional setting, the prolific generation of hydrogen from organic sources in the region appears to be a reality.

Summary: The study found that carbonate concretions preserve better paleoenvironmental information, and most of the molecular fossils are derived from surrounding rocks. However, the concretions contain higher organic matter content, indicating changes in biological equilibrium. The study concluded that carbonate concretions could better preserve molecular fossils and provide a valuable reference for research into early life forms.

Summary: Diabase intrusions play an important role in the formation of sandstone-type U deposits in the southwestern Songliao Basin. The discovery of U-bearing carbonate minerals in the BLS U deposit provides evidence for hydrothermal U mineralization related to diabase intrusions. The occurrence of uranyl carbonate minerals can be attributed to CO2-rich hydrothermal fluids from diabase intrusions.

Summary: By quantifying the shear wave splitting parameters captured by three seismic arrays in Northeast China, we studied the origin of intraplate volcanism and found a toroidal pattern of anisotropy beneath the Songliao Basin. The high-density seismic array revealed that the Pacific subduction and lithospheric foundering processes controlled the genesis of late Cenozoic volcanism in Northeast China.

Summary: Continental rifts, such as the Songliao Basin in NE China, are influenced by both shallow and deeper processes related to the dynamics of the mantle. The evolution of the Songliao rift volcanism during the Cretaceous can be divided into five stages dominated by crystal fractionation. The magmas originated from a veined asthenospheric mantle and a metasomatized sub-continental lithospheric mantle, suggesting a subduction-related rift caused by the eastward rollback of the Paleo-Pacific slab.

Summary: The development of marine carbon sequestration project has the potential to neutralize carbon in the short-term. This technology is based on biological and carbonate pumps to increase particulate organic carbon and authigenic insoluble carbonates to achieve permanent carbon sequestration. However, potential risks to marine ecosystems and organisms must be considered. Chemical carbon sequestration through mineral addition and CO32- combination has been proposed to improve the capacity of marine carbon fixation. The effects of this method on marine organisms include the release of chemicals and the formation of particles, which can have toxic effects on phytoplankton, bacteria, and filter feeding organisms.

Summary: This study detected widespread clay minerals on Mars using near-infrared spectroscopy but acknowledged its limitations. By analyzing terrestrial analogues in the Qaidam Basin, the study identified illite and chlorite mineralogy in surface coatings. Results suggest that even small amounts of clay minerals on sands can affect NIR absorption, impacting mineral detection on Mars.

Summary: In this study, the influence of nitrogen-doped and non-doped mesoporous carbon materials (NCMK-3 and CMK-3) on the persulfate (PS) oxidation of 4-chlorophenol (4CP) in water was investigated. The results showed that both NCMK-3 and CMK-3 facilitated the removal of 4CP from water. NCMK-3 exhibited better performance compared to CMK-3. NCMK-3 influenced the thermodynamic process and exhibited a synergistic effect in the removal of the organic contaminant from water.

Summary: Two kinds of Mg-Al-layered double hydroxides (LDH-1 and 2) were synthesized and used to adsorb PFOA from aqueous solution. The removal rates of PFOA adsorption by LDH-1 and LDH-2 were 90% and 98.9%, respectively, in the lowest time compared with similar past studies using different adsorbents. The research demonstrates the potential of employing synthesized LDHs in a fixed-bed filter for the environmental remediation of PFOA-contaminated wastewater bodies.

Summary: FeS was selected as a heterogeneous activator of persulfate (PS) for the degradation of a typical recalcitrant contaminant, DR81. Efficient degradation of DR81 was achieved by the FeS/PS system due to the generation of highly reactive SO4• and •OH. The operational parameters had insignificant effects on the decoloration of DR81, while different inorganic anions showed distinct impacts. FeS/PS system exhibited good adaptability and stability in the degradation process.
