Summary: Understanding the variations in sulfur isotopic composition of sedimentary pyrite is essential due to the crucial role of sulfur biogeochemistry in regulating the Earth's surface oxidation state. Recent research reveals that local depositional conditions significantly impact the delta S-34(pyr) values, challenging the previous interpretation of stratigraphic variations as global biogeochemical cycling changes. The study demonstrates strong local controls on delta S-34(pyr) and calls for a reevaluation of using these variations to infer global changes in Earth's surface environment.

Summary: This study examined the depositional environments and petroleum source rock potential of Middle Jurassic and Lower Cretaceous lacustrine sedimentary rocks in central Mongolia. The Middle Jurassic shale was found to have a mixed oil and gas potential source rock, while the Lower Cretaceous shales showed a high oil-prone but thermally immature character. The organic geochemical characteristics and depositional environments of these rocks are similar to source rocks in western Chinese basins and eastern Mongolian basins, respectively.

Summary: This article reviews the possibility of establishing the depositional age and tectonic settings of metamorphosed carbonate rocks from continental collision zones in the East African-Antarctic Orogen, comparing them with similar occurrences in other regions. It discusses the variations in carbonate deposition ages in different areas, as well as the geochemical characteristics and REE patterns of meta-carbonate rocks. The study suggests that different regions have different sedimentation histories and sources of carbonate deposition.

Summary: Boiling is a crucial process in magmatic-hydrothermal systems, triggering ore formation and controlling the enrichment of precious and rare metals in epithermal-porphyry mineralizations. New data from sulfides in shallow-marine hydrothermal systems on Milos Island reveal insights into the diversity of mineralization processes and the mixing of fluids with different isotope compositions. In the Vani area, condensation of vapor and mixing with seawater caused Hg-Bi-Mo-As-rich mineralization, similar to the active hydrothermal system at Milos.

Summary: This study provides robust evidence for the survival of whole-rock Sm-Nd isotopes in the presence of multistage hydrothermal alteration. The Lala Fe-Cu-REE deposit in southwestern China is host to a variety of REE-rich minerals that underwent extensive metasomatic alteration. The results show that despite resetting of major REE minerals, the whole-rock Sm-Nd isotopic system remained closed.

Summary: The text discusses the features associated with crustal evolution and metallogeny in the Western Bastar Craton, Central India, focusing on expressive granitic magmatism and a complex fault and shear zone system. Barite mineralization in the area is hosted in the 1.6 Ga Mul granite, with different types of barite present. The study utilized a comprehensive approach to characterize the ore-forming processes, fluid source, and structural control of the barite mineralization.

Summary: The study investigated the ore-forming fluids and processes in the Gouli goldfield through a comprehensive analysis of the texture, geochemistry, and isotopes of pyrite. Four distinct types of pyrite were identified, indicating evidence for a multi-stage hydrothermal fluid evolution. The findings suggest that multiple pulses of ore-forming fluids were exsolved during sequential episodes of primarily crustal-derived felsic magmatism with lesser mantle influences.

Summary: The Paleoproterozoic metasedimentary rocks of the Zaonega Formation in NW Russia provide important information about global environmental changes after the initial oxygenation of the Earth's atmosphere and oceans. This study examines the geochemical signals preserved in these rocks and their environmental meaning, particularly focusing on the unusually high pyrite sulfur isotope ratios. The results show that the formation of pyrite in the Zaonega Formation occurred through multiple stages, and early-stage pyrite has different isotopic signatures compared to late-stage pyrite. The findings suggest that a thorough understanding of the geological context and mechanisms associated with sulfur cycling and pyrite formation is essential for interpreting the isotopic records accurately.

Summary: Potassium metasomatism is a common geological process that can change the chemistry of large volumes of crust, forming potassium-rich rocks. Remote sensing on Mars has revealed potassium-rich terrains and rocks with evidence of K-enrichment in Gale Crater. This study suggests that the presence of potassium-rich rocks on Mars is consistent with potassium metasomatism, while the possibility of metasomatized crust sourcing the abundant feldspar in Gale Crater.

Summary: The study explores the role of biogeochemical sulfur cycling during the Eocene-Oligocene transition, reporting a decline in seawater sulfate isotope values. Quantitative modeling suggests a significant reoxidation of sulfide from shelf sediments, affecting marine pH and alkalinity. The numbers are similar in magnitude to those observed during Pleistocene glaciations.

Summary: Petrographic and geochemical studies were conducted on the Paleocene-Eocene limestones of the Ewekoro Formation to investigate their depositional and post-depositional imprints. The research identified three distinct microfacies and variations in depositional environments. Analyzing rare earth elements, carbon and oxygen isotopes provided insights into the characteristics of the limestone and its diagenetic processes.

Summary: Pyrite oxidation plays a critical role in the relationship between weathering and climate, especially through inversion models utilizing observations of river sulfate and its isotopic ratio. Measurements in western Iceland show that sulfate mainly derives from basalt weathering, and different geological formations influence the availability of unweathered bedrock.

Summary: The term Anthropocene emerged in the early 2000s to signify the end of the Holocene Epoch due to human activities, initially linked to the Industrial Revolution and later associated with global industrialization and globalization. While the concept is being evaluated for inclusion in the Geological Time Scale, it has also been applied in various scholarly fields with broader interpretations extending beyond the mid-twentieth century.

Summary: Glass microspheres are widely used as reflective components in road and pavement marking materials. They are able to be distinguished from other morphologically similar particles in road dust. In Kielce road dust, glass microspheres range from 30 to 1350 ?m in diameter and consist mainly of recycled Ca-, Na-, Mg-silica glass with minor admixtures. They serve as good markers of traffic-related pollution in different environmental archives.
