The chemical composition, crystal and electronic structure and magnetic properties of the (Mg_1-xFe_x)₂SiO₄ olivines (nominal x=0.060 and 0.091), synthetic and terrestrial (Lower Silesia, Poland) were investigated by X-ray diffraction, photoelectron and Mössbauer spectroscopy, electron spin resonance and magnetostatic methods. It was found that in synthetic olivines the carbon, proceed from starting materials, located in the Mg sites lead to distortion of the crystal lattice.
