“…The term olivine, (Mg,Fe) 2 SiO 4 represents solid solutions of the isomorphous forsterite, Mg 2 SiO 4 , and fayalite, Fe 2 SiO 4 . The study of the IR spectrum of the olivine sample from Ržanovo [16,18,21] showed that the band frequencies are much closer to the corresponding bands in the spectrum of forsterite, Mg 2 SiO 4 ( Fig. 16 and Table 5).…”

“…23 in ref. 16), it was presumed that, more likely, some structural changes appear during the recording of the almandine FT-Raman spectrum [16,18]. Later it was shown [19] that the strong bands in the FT-Raman spectrum of almandine (at 607 and 446 cm -1 ) are fluorescence bands that appear from the traces of rare earth impurities in the sample (Figures 7 and 8).…”

“…18). It suggests that one should be careful during their use for identification purposes as well as for spectra-structure correlations [18]. In fact, all bands observed in the dispersive Raman spectrum are present in the FT-counterpart, where two additional strong bands at 607 and 446 cm -1 were registered.…”

“…6). It means that the vibrational frequencies of the almandine having smaller unit cell volume (1533.2 Å 3 ) are, in general, higher than those of spessartine whose unit cell volume is larger (1565.7 Å 3 ) [18]. In addition to XRPD, it enables to discriminate between these two isomorphous minerals by using the FT IR method.…”

Raman is an important tool for diagnosing minerals in geoscience. However, smaller magnification of optical microscope assembled in conventional Raman spectroscopy limits the application of Raman in sub-micro and nano scale. Raman imaging and scanning electron microscopy (RISE) combine the advantage of scanning electron microscope and Raman spectroscopy, which can collect the morphology, composition, and structure information in the same micro region of the geological sample in situ. In this paper, we introduce the development and working mechanism of RISE, and carried out some typical applications in different research of geoscience. The purpose of this review is to allow readers to understand the basic principles and application potential of RISE in geoscience. Finally, we briefly point out current challenges faced by this technology and some research directions in the future. Highlights• Raman imaging and scanning electron microscopy as potential method was proposed for the research on geosciences.• Common polymorphism and isomorphism were distinguished clearly in situ.• A new research route for tiny inclusion and organic matter in situ was developed.

Two strong bands centered at 446 and 607 cm −1 have been observed in the FT-Raman spectrum of almandine [Fe 3 Al 2 (SiO 4 ) 3 ] excited with 1064 nm, which were completely absent in the corresponding dispersive Raman spectra obtained using 488, 514.5 and 532 nm excitation. Furthermore, the mentioned strong bands have not been registered in the anti-Stokes side of the FT-Raman spectrum, and were therefore assigned to laser-induced fluorescence bands. Their appearance is related to the presence of rare-earth element traces as impurities in the almandine sample. Additionally, the FT-Raman (and dispersive Raman) spectrum of the isomorphous spessartine [Mn 3 Al 2 (SiO 4 ) 3 ] mineral has been introduced, which did not show the presence of these fluorescence emission bands. The purity of the minerals was confirmed by study of their powder X-ray diffraction (PXRD) patterns.
