Triple oxygen isotope compositions reveal transitions in the moisture source of West China Autumn Precipitation

Communications Earth & Environment
The isotopic composition has long been used to investigate the factors influencing precipitation, whereas the variations of event-based precipitation isotopes caused by moisture transition and synoptic meteorological conditions remain limited.

Revealing the Drivers of Unexpected High Nitrogen Levels in Tropical Rainforest Rivers in Winter

Ecosystem Health and Sustainability
Elevated river nitrogen (N) concentrations have contributed to eutrophication and subsequent ecological damage worldwide. However, current research has mostly focused on nitrate (NO3−) in rivers, with relatively few studies on the sources of different N ...

Fingerprinting Fluid Source in Calcite Veins: Combining LA-ICP-MS U-Pb Calcite Dating with Trace Elements and Clumped Isotope Palaeothermometry

Tektonika
Application of geochemical proxies to vein minerals - particularly calcite - can fingerprint the source of fluids controlling various important geological processes from seismicity to geothermal systems. Determining fluid source, e.g.
