... compositions. Configurational entropy of mixing models requires W Ri and W Tr to be reduced if the whole solid solution is stable at the synthesis temperature of 1123 K, but not if richterite-rich compositions are metastable. The similarity between Δ H mix of tremolite-richterite and fluor-tremolite-fluor...

...) , and the present study. Amphiboles ( e.g., fluor-edenite, F-rich tremolite) and Ca-rich pyroxenes ( e.g., diopside) are not common minerals in granitic pegmatites, but are quite common in mafic or peralkaline pegmatites. Calcic pyroxenes like diopside, though unusual, are present in Li- and B-rich...
