Stable Isotopes Principles of stable isotope fractionation

Stable Isotopes Principles of stable isotope fractionation. Annual layers in a tropical ice cap. Stable isotopes. Many elements of low atomic weight have two or more stable isotopes, e.g.: Hydrogen - H, D, T Carbon - 12 C, 13 C Nitrogen - 14 N, 15 N Oxygen - 16 O, 17 O, 18 O
