Quantitative analysis of hydrated minerals from hyperspectral remote sensing data is fundamental for understanding Martian geologic process. Because of the difficulties for selecting endmembers from h...
We present an empirical model of sulphur solubility that allows us to calculate f S2 if P, T, fO2 and the melt composition, including H2O and S, are known. The model is calibrated against three main ...
Teleseismic converted phases are used to probe the composition of the downgoing oceanic crust as a function of depth along the Cocos slab in central and southern Mexico. Previously, modeling of the re...
The presence of volatile species in the Earth’s upper mantle drives the formation of low-degree melts at pressures and temperatures at which volatile-free mantle rocks would be subsolidus. The two ...
The distribution of the rare earths and yttrium (REY) in co-existing hydrous Mn oxides and Fe oxides that form marine hydrogenetic ferromanganese crusts is used to better describe the partitioning and...
The major element, trace element, and isotopic composition of mid-ocean ridge basalt glasses affected by the Azores hotspot are strongly correlated with H2O content of the glass. Distinguishing the r...
Reaction of a hydrous mineral with a water-bearing silicate melt is analyzed in terms of the sto- ichiometry of (in)congruent dissolution. Application of the law of mass action provides an explana- ...
Changes in configuration and hydrogen bonding are inferred from the complex responses of peak parameters (frequency, width, height, and area) to compression for various hydroxyl groups) depend not on...

Phase egg, first described by Eggleton et al. (1978), was synthesized and its composition determined to be AlSiO3OH. The crystal structure of AlSiO3OH, including the position of the hydrogen, has been...
Twenty-two andradite samples from a variety of geological environments and two syn-thetic hydroandradite samples were studied by Fourier transform IR spectroscopy. Their spectra show that H enters and...
The structure of sodium tetrasilicate (Na2Si4O9) glasses containing 0 to 10 wt% water was investigated by a combination of Raman, IR, and NMR methods. Both the 29 Si magic angle spinning NMR data and...
We performed 27 viscosity determinations on dry and water-bearing peraluminous hap-logranitic melts. The dry melt compositions cover the range of normative corundum to be expected in peraluminous gran...
