| Most stable isotope geochemistry is performed on the light elements Oxygen, Carbon, Hydrogen, and Sulphur. Analyses can be performed on whole-rock samples, carbonate and evaporite mineral components, or reservoir fluid samples. These analyses require highly specialised equipment and are performed at a university or a commercial isotope lab. Information can be obtained about the source of the element (for example, the relative contribution of organic matter or fresh water) and the temperature of mineral precipitation. |
