A combined temperature dependent57Fe Mössbauer and single crystal X-ray diffraction study of synthetic almandine: evidence for the Gol'danskii-Karyagin effect
Synthetic almandine garnet, Fe3Al2Si3O12, has been studied by temperature — dependent single crystal X-ray diffraction and57Fe Mössbauer spectroscopy. The Fe2+ doublet in almandine is characterized by a small asy...

Prediction of refractive indices in minerals from crystallographic data: Applications and limitations of the point-dipole model
A point-dipole calculation which incorporates an expression for the Lorentz-factor tensor has been used to model the effect of chemical substitution on refractive index and optic axial angle (2V). Isotropic elect...
