;
 Crystal-structure refinement of synthetic Fe- and Mg-staurolite by
 Rietveld analysis of X-ray powder-diffraction data
 Sample: Fe-staurolite synthesized at 5 kbar
 Note: These coordinates do not reproduce the reported bond lengths, but
 Koch-Muller tells me that the coordinates are correct, and the reported
 bond lengths were incorrect.
