    • A model for germanium-silicon equilibrium fractionation in kaolinite 
      Pérez Fodich, Alida; Derry, Louis A. (Elsevier, 2020)
      Germanium is a useful tracer of silicate weathering and secondary mineral formation in the Critical Zone because Ge/Si ratios are fractionated during incongruent weathering of silicates. We develop an estimate of the ...
