Abstract:Povlen type hydroxyl-chrysotile is a new variety of Povlen type chrysotile, whose absorption, infrared, Mossbauer, EPR and NMR spectra are reported in this paper. Experimentation shows that the absorption spectra are caused by crystal-field transitions of Fe3+ and Fe2+ ions and charge-transfer transition of Fe3+→Fe3+, the infrared spectra by stretching vibrations of OH and Si-O, rotation of OH and bending vibrations of Mg-O and Si-O, the Mossbauer spectra by Fe2+octa.,Fe3+octa., and Fe3+tetra., the EPR spectra by Mno2+octa., Fe3+octa and Fe3+tetra.,and the NMR spectra by pipe water in fibre and OH on Mg-octahedra and Si-0 tetrahedra. It is also demonstrated that, when heated to 825℃,the structure was destroyed and forsterite phase formed. In addition, this paper interprets the color of Povlen type hydroxyl-chryso- tile and describes structural environments of the above transitional metal ions and OH in this mineral.
