The stable isotopes of hydrogen (δ2H) and oxygen (δ18O) have been widely applied in hydrology. The equation relating δ2H to δ18O in precipitation, also defined as a meteoric water line, can provide a reference point for interpretation of stable isotopic compositions of a range of water samples in an area. Influenced by many spatial and meteorological factors, the slopes and intercepts of meteoric water lines vary depending on location. Read more.
