Summary: The sedimentary studies from the Marinoan deposits in South China provide a basis for establishing a sequence stratigraphic framework that includes two complete glacial cycles. These cycles demonstrate a pattern of ice-advance and ice-retreat successions, with corresponding changes in sedimentary facies and lithofacies association. The dynamic co-evolution of sedimentary environments, paleoclimate, and sea level during the Marinoan glaciation is indicated by this sequence stratigraphic framework.

Summary: This study reports a diverse and well-preserved in situ vase-shaped microfossil assemblage within glacially influenced deposits in Brazil, challenging the previous belief that these organisms disappeared at the end of the Tonian. Recent multi-proxy correlation suggests a Marinoan age for the studied succession.

Summary: This passage discusses the importance of ancient glacial deposits in understanding Earth's climate during the Cryogenian Period, as well as the challenges in determining the past positions of grounded ice, its thermal regime, and flow direction. The study found that Cryogenian subglacially striated surfaces are globally rare but are crucial indicators of the presence of ice and thermal regime.

Summary: The Haobugao Zn-Fe-Sn skarn deposit in NE China contains three generations of garnets with distinct characteristics. The formation of these garnets reflects the evolution of hydrothermal fluids in the skarn system, with different generations forming under varying water/rock ratios and pH conditions. The variation in rare earth element content and fractionation of the garnets suggest fluctuations in fluid composition, likely influenced by magmatic and meteoric water inputs.

Summary: This study investigates the genesis of the Fulu iron formation in South China through major and trace element data and Fe-Nd isotope systematics. The study proposes an interglacial Fe2+ oxidation model to explain the sedimentological and geochemical characteristics of the Fulu iron formation. The study also suggests that the geochemical variability within the Fulu iron formation is caused by mixing between detrital and hydrothermal components.

Summary: The terrestrial habitats during the Cryogenian period were possibly covered by global snow and ice. Recent studies suggest that multicellular charophytes evolved in response to Cryogenian cooling. This period also saw the likely origin of the common ancestor of Zygnematophyceae and Embryophyta. The expansion of terrestrial flora during the Marinoan glaciation was represented not only by Chlorophyta but also by Streptophyta and Zygnematophyceae.

Summary: The presence of trace amounts of dissolved cerium is shown experimentally to increase the porosity of hematite formed via fluid-induced replacement of magnetite, enhancing efficiency of magnetite replacement, fluid flow, and element mass transfer. Cerium acts as a catalyst affecting the nucleation and growth of hematite, ultimately controlling the kinetics, texture, and composition of fluid-mineral systems. This study provides new insights into how trace elements like cerium can precondition ore systems for enhanced metal accumulation, contributing to the large size and metal endowment of world-class ore deposits.

Summary: This study conducted a systematic trace element geochemical analysis using the sediment core SO184-10043 to reconstruct the marine redox environment (MRE) over the past 35,000 years. The results showed that the variability in MRE was consistent with high-latitude climate records, influenced by the summertime insolation and the motion of the Intertropical Convergence Zone (ITCZ) and monsoon system in the tropical Indian Ocean. The presence of freshwater lids acted as barriers and influenced upwelling development, resulting in strong oxic conditions in the MRE.

Summary: This article reviews the literature on the relationship between the concentration of selected elements in the serum of patients with major depressive disorder (MDD) and the onset and progression of this psychiatric condition. According to the results, metallomics may serve as a potential screening tool for patients with MDD, providing assessment of symptom severity. Deficiencies or excessive amounts of selected elements may be associated with the progression of depressive symptoms or even the onset of the disease in individuals predisposed to MDD.

Summary: The seawater chemistry of the Cryogenian Nanhua Basin was significantly influenced by the fluxes of freshwater and seawater, with black shale deposition associated with low salinity and Mn-carbonate deposition linked to higher salinity. During anoxic depositional intervals, enhanced decay of organic matter led to C-12-enriched dissolved inorganic carbon precipitating in Mn-carbonates.

Summary: Colloidal transport of major and trace elements in surface and soil waters is well-established in boreal and subarctic regions. However, little is known about the colloidal associations of organic carbon and major and trace elements in atmospheric precipitation such as snow. In this study, snow cores from western Siberia were analyzed, revealing significant proportions of major and trace elements in the colloidal form. The findings suggest the importance of further research on atmospheric colloids.

Summary: This study demonstrates that in situ oxygen isotope analysis of cassiterite is a promising tool to refine sources of ore-forming fluids, and to decode hydrothermal dynamics controlling tin and tungsten mineralization. Oxygen isotope analysis of cassiterite samples from six Sn(-W) deposits in China shows considerable variability in delta O-18 values, revealing a strong magmatic affinity with variable or low involvement of meteoric water in ore-forming fluids. This suggests a reevaluation of the role of meteoric water in Sn-W mineralization.

Summary: The study investigates the dynamic redox changes in a large lake in central China during the Paleocene-Eocene Thermal Maximum (PETM) using isotopic methods. Three major anoxic episodes were identified, likely caused by thermal stratification in the lake. The findings suggest that current global warming may lead to similar ecological stress in large lakes through enhanced nutrient fluxes and expansion of anoxic zones.

Summary: Biosilicification, the process of forming biological structures composed of silica, is widely distributed among eukaryotes and plays a significant role in global biogeochemical cycles. Recent discoveries of silica transporter genes and silicon accumulation in bacteria suggest that prokaryotes, particularly in ancient times, may also have played a previously unrecognized role in the Si cycle. This study reports the identification of a magnetotactic bacterium that forms intracellular, amorphous silica globules, revealing intracellularly controlled silicification within prokaryotes and its potential influence on the biogeochemical Si cycle during early Earth history.

Summary: This study found that cows with mastitis had significant gut dysbiosis, characterized by enrichment of opportunistic pathogenic bacteria and depletion of commensal bacteria. Fecal microbiota transplantation from cows with mastitis to mice induced mastitis and altered gut and mammary microbiota in mice. The commensal bacteria improved mastitis symptoms by producing butyrate, limiting bacterial translocation.

Summary: The activation of intestinal microbiota-mediated AhR plays an important role in infection-induced inflammation, and can be regulated by dietary Trp and probiotics. The study found that AhR activation alleviated endometritis by repairing barrier function and inhibiting inflammatory responses, while inhibition of AhR aggravated the disease. Gut dysbiosis damaged AhR activation and exacerbated endometritis. Supplementation with dietary Trp and AhR ligands, as well as the use of probiotics, showed protective effects against endometritis. These findings provide potential strategies for intervention in infectious diseases and reproductive health by regulating gut microbiota and metabolism.
