(a) The instrumental mass fractionation (IMF) is a linear function of Fe (apfu) and Altot (apfu). This is illustrated in the excellent correlation in measured vs. calculated IMF obtained for an individual SIMS session (see text for further explanations). (b) Illustration of the variation of IMF with chemical parameters: Fe (apfu) (solid solution dravite-schorl) and Altot (apfu) (solid solution schorl-elbaite-darrellhenryite). Note that the effect on IMF of Fe-Mg exchange is larger than the Al1Li1-Fe2 exchange. Error bars are uncertainties of the IMF (sIMF) determined as described in the text. Black squares represent end-member compositions.
