Iron isotope fractionation during proton- and ligand-promoted dissolution of primary phyllosilicates

We studied stable iron isotope fractionation during dissolution of a biotite and chlorite enriched mineral fraction from granite by HCl and 5 mM oxalic acid in a pH range of 4–5.9. Batch experiments covered a time period from 2 h to 100 days and were performed at initial potassium concentrations of...
