Metal stable isotope signatures as tracers in environmental geochemistry

JG Wiederhold - Environmental science & technology, 2015 - ACS Publications
The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

Equilibrium fractionation of non-traditional isotopes: a molecular modeling perspective

M Blanchard, E Balan… - Reviews in Mineralogy …, 2017 - pubs.geoscienceworld.org
