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 …
