Webb5 juli 2024 · A wide range of natural K-, Na-, Ca- or (K + Li)-micas have been systematically examined by Raman spectrometry. The spectra are interpretable in terms of regular variations in peak positions and chemical parameters. Several vibrations give higher wavenumbers for Na-micas compared to K-micas, in accord with the smaller ionic size … WebbFirst, we looked for amphiboles by optical microscopy using the description of Treiman (1985, 1998) and analyzed them by electron microprobe. Then, Raman spectra were …

Webb1 juli 2024 · Raman-active modes carry essential chemical information, which allows for discriminating different species within the mineral group (e.g. amphibole group). In contrast to electron microprobe analysis, light elements such as hydrogen and lithium can be detected by Raman spectroscopy through the corresponding atomic vibrations.

Calcite grains range from 50 μm to 3 cm in size; in contrast to the saccharoidal calcite, larger grains are strongly deformed, aligned with the foliation and contain abundant primary micro-inclusions of celestine and Sr-rich anhydrite, whose identity was confirmed by Raman spectroscopy.
