The peak positions of the Raman bands correlate with content of major components of garnets. Raman shift of stretching ν1 and bending ν2 vibrations reflects Ca–Mg and Al–Cr isomorphism. The found correlations have been applied for rough estimation of the garnet compositions. This method allows to discriminate E-type and P-type garnets marking diamondiferous mantle rocks.
