A re-examination of thortveitite
American Mineralogist (June 1988) 73 (5-6): 601-607


Four different natural crystals of thortveitite (Sc,Y) (sub 2) Si (sub 2) O (sub 7) have been analysed by electron microprobe, and the structure has been determined from single-crystal data using MoKalpha radiation up to at least theta = 40 degrees (final R approx 0.02). A Si-O-Si angle of 180 degrees is confirmed with crystal symmetry C2/m.
