We have measured in situ M6ssbauer transmission spectra of iron silicate spinel in a diamond anvil cell at room temperature and pressures up to 16 GPa. The observed spectra show a doublet characteristic of the paramagnetic state. The isomer shift and quadrupole splitting at atmospheric pressure are
## Abstract The Mössbauer resonance absorption is measured in various silicates containing iron. The observed isomeric shifts are in accordance with the interpretation of WALKER. Even for Fe^3+^ ions, large quadrupole splittings are found. The analysis of the spectrum of tourmaline is similar to th
