Discussion of recent papers on carbonated peridotite, bearing on mantle metasomatism and magmatism: response

I agree with Eggler [1] that there is no discrepancy in the "10-kbar difference in pressure between the pseudoinvariant point H_2 of Olafsson and Eggler [2] and an invariant point I_6 in CaO- MgO-SiO_2-CO_2" if the topology shown in his Fig. 1 is established. My discussion [3], however, was more concerned with the difference of about 8 kbar between the points H_2, related to the range of amphibole stability, in the only two experimental studies reported on the solidus for dolomite-amphibole- peridotite [2,4], which are reproduced in my Fig. 1A and 1B [3]
