Observations of groundwater-surface water exchange effects on emerging pollutants in a subtropical catchment

The occurrence of emerging pollutants (EPs) in aquatic environments is a major threat to natural ecosystems and human health, but the connections between EPs in surface water and groundwater have been largely unexplored. Here, a total of 38 EPs, including antibiotics, per- and po...

Seasonal variations of soil water vapor distribution transport and phase transition in the loess unsaturated zone from fixed volume monitoring

Abstract Water vapor is a crucial yet often overlooked water resource in the soil’s unsaturated zone of arid and semi-arid regions. Understanding water vapor behavior in the soil’s unsaturated zone is crucial for research on soil and energy balance, vegetation water stress, and w...

Three-Dimensional Identification of In Situ and Migrated Organic Matter in Shale Based on Micro-CT

Accurate differentiation of in situ organic matter (IOM) from migrated organic matter (MOM) and their three-dimensional characterization are fundamental for understanding hydrocarbon generation, migration, and accumulation in shale reservoirs. However, conventional micro-computed...

The Cambrian Magmatic Evolution in the Damara Belt, Namibia: Constraints from Garnet-Bearing Granites

Abstract Garnet is a petrogenetic key indicator, common in igneous and medium- to high-pressure metamorphic rocks. It provides valuable constraints for pressure–temperature–time paths in orogenic belts and offers insight into magma generation, evolution, and crystallization. To i...
