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.

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.
