Stable isotope geochemistry explores how isotopes behave in natural systems. It covers fractionation processes, analytical techniques, and applications in various Earth systems, from the atmosphere to the lithosphere.
This field helps scientists understand paleoclimate, biogeochemical cycling, and planetary formation. It also has practical uses in environmental studies, ecology, and even extraterrestrial research.
