Inclusions of nanocrystalline hydrous aluminium silicate “Phase Egg” in superdeep diamonds from Juina (Mato Grosso State, Brazil)
TL;DR: In this paper, Schmidt et al. used focused ion beam (FIB) to detect a porous, nanocrystalline groundmass, which is composed of nanometre-sized crystals of a hydrous aluminium silicate phase with Al:Si approximately 1:1 and chemical composition of phase "Egg" (AlSiO 3 (OH)), a minor volume fraction of nanocrystine stishovite and pore space, which was originally filled with a fluid or gas.

TL;DR: In this paper, the mineral-specific IR absorption coefficients were calculated for natural and synthetic olivine, SiO2 polymorphs, and GeO2 with specific isolated OH point defects using quantitative data from independent techniques such as proton-proton scattering, confocal Raman spectroscopy, and secondary ion mass spectrometry.

TL;DR: The incorporation of hydrogen in mantle olivine xenocrysts from the Udachnaya kimberlite pipe was investigated by Fourier transform infrared spectroscopy and secondary ion mass spectrometry (SIMS) as discussed by the authors.

Dehydration experiments on natural omphacites: qualitative and quantitative characterization by various spectroscopic methods
TL;DR: In this paper, a series of natural omphacites from a wide range of P, T occurrences were investigated by electron microprobe (EMP), infrared (IR)-, Mossbauer (MS)- and optical spectroscopy in the UV/VIS spectral range (UV/VIS), secondary ion mass spectrometry (SIMS) and single crystal structure refinement by X-ray diffraction (XRD) to study the influence of hydrogen loss on valence state and site occupancies of iron.
Optical absorption study of natural garnets of almandine-skiagite composition showing intervalence Fe2+ + Fe3+ → Fe3+ + Fe2+ charge-transfer transition
TL;DR: A broad (FWHM ≈ 7300 cm−1) intense band at ~21 700 cm− 1 in the optical absorption spectra of natural Fe2+, Fe3+-rich garnets is attributed to electronic intervalence charge-transfer transitions (IVCT), VIIIFe2+ + VIFe3+ → VIIIF e3++ VIF e2+. In Fe3+, Fe2+-bearing garnets of predominantly almandine compositions, this band causes yellowish tinges in addition to the pink color, typical of pure Fe 3+-
