Chemical compositions of low- and high-Ca pyroxenes in RB-QD04-0008 and RB-QD04-0024 plotted on a pyroxene quadrilateral diagram. (a) An enlarged diagram showing a chemical composition of high-Ca pyroxene in RB-QD04-0008. (b) An enlarged diagram showing those of low-Ca pyroxene in RB-QD04-0024. Chemical compositions of pyroxenes included in highly equilibrated and poorly equilibrated particles investigated by Nakamura et al. (2011) are also plotted for comparison.
