I have been modeling an intermediate magma but haven't been able to get amphibole and pyroxene to output properly. In order to get any amphibole to be part of the output I have to deselect pyroxenes from the available phases. Otherwise, all I get is pyroxene with no amphibole phase present. I have widely adjusted the H2O values with no change to this problem. I've tried this with both MELTS for Excel and rhyolite-MELTS 1.1.0 with the same results.
