摘要: A SAMPLE of natural stishovite1 (SiO2), purified by Dr. D. J. Milton, extensive HF digestion Coconino sandstone, from Meteor Crater, Arizona, was studied infra-red absorption techniques. marked shift to lower frequencies 400 cm−1 has been observed in the position maximum peak when compared with that more usual tetrahedrally co-ordinated silica minerals, quartz, coesite, and fused silica.
