The quantitative determination of moganite in flint and chert plays an important role in the characterisation of these silica rocks and in the study of their genesis and evolution. Both Raman and infrared (IR) spectroscopy promise to be rapid and cost-effective tools for such studies. However, the use of vibrational spectra of moganite in silica rocks is hampered by the proximity of specific moganite bands with IR and Raman vibrations bands of non-bridging Si-O in silanol (SiOH) groups of… Expand
