Abstract

This paper reports the Raman spectrometric and X-ray diffraction analyses of structural characteristics of opals from the most important localities (Mexico, Australia, Brazil). Volcanic opals from Mexico have similar Raman spectra characterised by a very strong general band… in order to continue, download the full paper in PDF
