2016-4-15 · An additional uncertainty arises for the kyanite-/diamond-bearing samples in this study. Kyanite is virtually devoid of trace elements, except for Ti, V and Cr, the concentrations of which are much lower than in garnet and cpx (Jacob et al., 2009), and its main effect is to dilute the bulk-rock trace-element content, excepting Al 2 O 3. Thus, samples reconstructed without kyanite likely return maximum concentrations, but the exclusion or inclusion of kyanite …
