The raman study of amphiboles
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.

Given the key role of fibre length in the mechanisms of asbestos toxicity, much work has been devoted to finding suitable comminution routes to produce fibres in desired size intervals. A promising method is …

Webb1 aug. 2015 · In this study, the AMS is characterized in 28 single crystals and 1 crystal aggregate of compositionally diverse clino- and ortho-amphiboles. High-field methods were used to isolate the paramagnetic component of the anisotropy, which is unaffected by ferromagnetic inclusions that often occur in amphibole crystals. Webbamphiboles are also common. 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.

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 … small red watering canWebbAmphiboles are minerals of either igneous or metamorphic origin.
