TLDR
In this paper, the authors quantified the matrix effect of external calibration procedures for quantification of the total H2O content (H2OT = O(OH−++H2Om) in natural silicate glasses, based on the calibration of either the absolute (external calibration) or scaled (parameterisation) intensity of the 3550 cm−1 band.About:

Journal ArticleDOI
Why do mafic arc magmas contain ∼4wt% water on average?
TL;DR: In this article, the authors studied the H2O contents of the least degassed melt inclusions from each volcano and found that the mean and common average values for H2Os are within one s.d.
Journal ArticleDOI
Applications of Micro-Fourier Transform Infrared Spectroscopy (FTIR) in the Geological Sciences—A Review
TL;DR: These investigations demonstrate that the employment of high-resolution micro-FTIR imaging enables visualization and mapping of the distributions of organic matter and minerals on a micrometer scale in geological samples, and promotes an advanced understanding of heterogeneity of organic rich coal and shale.
Journal ArticleDOI
Volatile loss from melt inclusions in pyroclasts of differing sizes
TL;DR: This paper investigated the loss of H2O from olivine-hosted melt inclusions (MIs) by designing an experiment using tephra samples that cooled at different rates owing to their different sizes: ash, lapilli, and bomb samples that were deposited on the same day (10/17/74) of the sub-Plinian eruption of Volcan de Fuego in Guatemala.
Journal ArticleDOI
Water in granite and pegmatite-forming melts
Rainer Thomas,Paul Davidson +1 more
TL;DR: In this paper, water concentration data obtained from melt inclusion in minerals, mostly quartz and topaz, from granites and pegmatites, from natural glasses are compiled, and a large range of water contents are found: from 2 to more than 50% water with two distinct maxima at 10.5±8.1 and 26.2±14.3%.

Magma and volatile supply to post-collapse volcanism and block resurgence in Siwi Caldera (Tanna Island, Vanuatu Arc)

TL;DR: In this paper, complex spatterand pumice-rich pyroclastic deposits from an andesitic caldera forming eruption are described. But the authors focus on the Siwi sequence.

Infrared and Raman Spectra of Inorganic and Coordination Compounds
TL;DR: In this article, the normal modes of vibration are illustrated and corresponding vibrational frequencies are listed for each type, including diatomic, triatomic, fouratomic, five-atomic, six-atomic and seven-atomic types.

Viscosity of magmatic liquids: A model
TL;DR: In this paper, a model that predicts the non-Arrhenian Newtonian viscosity of silicate melts as a function of T and melt composition, including the rheologically important volatile constituents H2O and F, is presented.
Journal ArticleDOI
The compressibility of silicate liquids containing Fe 2 O 3 and the effect of composition, temperature, oxygen fugacity and pressure on their redox states
TL;DR: In this paper, the authors extended the empirical expression of Sack et al. to allow the calculation of Fe-redox equilibrium in a natural silicate liquid as a function of composition, temperature, fo2 and pressure; a more formal thermodynamic expression is presented in the Appendix.

Water in silicate glasses: An infrared spectroscopic study
TL;DR: In this paper, infrared and near-infrared transmission spectra have been taken on 19 volcanic and synthetic silicate glasses with known H2O contents (0.06-6.9 wt. %).
