Chandrasekhar, "Synthesis of a-cordierite (indialite) from flyash," Materials Research Bulletin, vol.
He details the chemistry, taxonomy, formation, and geochemistry of the beryl group of gemstones, and then information on each mineral--bazzite, beryl, indialite, pezzottaite, and stoppaniite--including its locality, etching and surface features, and many color photos.
Beryl ([Be.sub.3][Al.sub.2][Si.sub.6][O.sub.18]), bazzite ([Be.sub.3][Sc.sub.2][Si.sub.6][O.sub.18]), stoppaniite ([Be.sub.3][Fe.sub.2.sup.3+][Si.sub.6][O.sub.18]) and indialite ([Al.sub.2]Si[Mg.sub.2][Al.sub.2][Si.sub.4][O.sub.18]) are isostructural with space group symmetry P[6.sub.3]/mcc, whereas pezzottaite, Cs[Be.sub.2]Li[Al.sub.2][Si.sub.6][O.sub.18], is rhombohedral with space group symmetry R[bar.3]c.
