The raman study of amphiboles

WebbRepresentative micro-Raman spectra of glasses and amphiboles are shown in the Supplement (Figs. S2 and S3). In three samples, the percentage of amphibole spectra displaying the most intense peak near 750 cm −1 does not differ much from that of the amphibole standards: 58 % of all acquired spectra in sample 17-7C, 69 % in sample 17 … WebbThis study describes the field relationships, petrography and geochemistry of various metamorphic and magmatic rocks from the Barru Block, South Sulawesi, Indonesia, and reports Rb-Sr isochron ages for clastic metasedimentary rocks.

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. WebbAmphiboles are minerals of either igneous or metamorphic origin. Amphiboles are more common in intermediate to felsic igneous rocks than in mafic igneous rocks, [8] because the higher silica and dissolved water content of the more evolved magmas favors formation of amphiboles rather than pyroxenes.

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. WebbWe present details of a field-based study on the evolution of alkaline to peralkaline rocks from the Mont Saint-Hiliaire complex, Quebec, Canada. The progressive magmatic evolution of the complex is represented by three melt batches: (1) primitive gabbroic rocks (XFecpx = 0.17-0.27, where XFecpx = molar Fe tot /(Fe tot

Webb4 feb. 2010 · Abstract Abstract— We studied micro Raman spectroscopy of amphiboles and pyroxenes in the martian meteorites Zagami and Lewis Cliff (LEW) 88516. The obtained Raman spectra of the amphiboles are similar to those of kaersutite, reconfirming the previous studies that they are kaersutitic amphiboles enriched in Ca, Al, and Ti. Webb9 apr. 2024 · For more than 40 years, intensive research has been devoted to shedding light on the mechanisms of asbestos toxicity.
