Late Triassic Hydroclimatic Changes in Central China Linked to Evolving Mountain Topography
Abstract During the Late Triassic, tropical Pangea drifted northward into subtropical latitudes and became progressively drier. In contrast, South China, despite experiencing a similar latitudinal shift, transitioned from an arid to humid climate. Based on the sedimentary record of the Zigui Basin, this study constrains the arid to humid climatic shift

Microbially-induced Carbonate Precipitation for Immobilization of Toxic Metals [PDF]
Rapid urbanization and industrialization resulting from growing populations contribute to environmental pollution by toxic metals and radionuclides which pose a threat to the environment and to human health.

Abstract Global warming enhances soil moisture (SM)‐temperature (SM‐T) coupling, exacerbating extreme climates. However, the mechanisms and future trends of this enhancement remain inadequately understood. Analysis of multiple reanalysis data sets shows that during summer seasons of 1981–2020, approximately 45.6% of global lands exhibit a significant ...

Sediments, unlithified and lithified microbial mats in the Salar de Atacama, are formed by similar pathways involving coupled precipitation of authigenic Mg silicate and calcium carbonate. Differences in products reflect differences in the initial distribution of organic biomass.

The impact of space flight on survival and interaction of Cupriavidus metallidurans CH34 with basalt, a volcanic moon analog rock [PDF]
Microbe-mineral interactions have become of interest for space exploration as microorganisms could be used to biomine from extra-terrestrial material and extract elements useful as micronutrients in life support systems.

Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

Abstract We rely on a global sensitivity analysis (GSA) approach to identify the dominant physical and biogeochemical controls on dissolved oxygen (DO) dynamics in riparian aquifers. The study is motivated by the observation that availability of DO is key to regulating redox conditions and associated processes in the subsurface.
