The introduction of new mass spectrometers in the form of multicollector ICP-MS has provided Geochemists with the ability to detect with high precision minor shifts on the stable isotopes of the metal and metalloid elements that are induced by physico-chemical reactions. Read more...
Fluid solid interaction redistributes isotopes between different compartments (e.g. minerals & water). Larger relative mass differences in isotope ratios lead to a larger shift in the 7Li/6Li ratio during isotope fractionation. Read more...
