T he isotope composition of natural material can vary, either through the decay of a radioactive parent that results in radiogenic ingrowth of a particular isotope, or as a product of chemical reactions driven by physical changes, for example, during the interactions between biosphere, hydrosphere, and rocks (1). Stable-isotope fractionation can reach levels of several percent for light elements, such as hydrogen, carbon, nitrogen, oxygen, or sulfur. However, the magnitude of isotope… CONTINUE READING
