Stable Isotopes

Stable Isotopes

Refers to non-radioactive isotopes of elements, including those of oxygen, hydrogen, carbon, sulfur, and nitrogen. In geothermal geochemistry, the stable isotope ratios of oxygen (18O/16O) and hydrogen (2H/1H) in thermal waters are used to trace its origin (e.g., meteoric, magmatic).
