Abstract Synthetic Mg2TiO4 qandilite was investigated to 50 and 40.4 GPa at room temperature using Raman spectroscopy and X-ray diffraction, respectively. The Raman measurements showed that cubic Mg2TiO4 spinel transforms to a high pressure tetragona

The dominant phases of Earth’s upper mantle are commonly referred to as nominally anhydrous minerals (NAMs) but may contain significant amounts of water. The colloquial term “water” in NAMs is related to the presence of hydroxyl-bearing (OH-) p

It is well known that some garnet compositions can incorporate hydrogen and/or fluorine at levels up to several wt%. However, accurate measurement of these elements can be difficult at trace to minor concentration levels, so they are frequently ignor

In order to extend the pressure and compositional range where silicate melts can be quenched to form glass in a multi-anvil high-pressure and high-temperature apparatus, a rapid-quench technique, which includes an external cooling system and a low th

Raman spectra at 298 K of the SiO4 symmetric stretch region (800–1200 cm−1) for low alkali (M) silicate glasses (5 and 10 mol% M2O, for M = Cs, K) yield intense well-resolved Q3 peaks at ~1100 cm−1 with mostly Lorentzian character, in contrast
