TARGET TRANSFORMATION CONSTRAINED SPARSE UNMIXING (TTCSU) ALGORITHM FOR RETRIEVING HYDROUS MINERALS ON MARS: APPLICATION TO SOUTHWEST MELAS CHASMA
Prior information Sparse unmixing Hydrous minerals Mars CRISM
2018/5/15
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...
Hydrous, Low-carbon Melting of Garnet Peridotite
Hydrous Low-carbon Melting Garnet Peridotite
2014/4/8
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

A hydrous melting and fractionation model for mid-ocean ridge basalts: Application to the Mid-Atlantic Ridge near the Azores
A hydrous melting mid-ocean ridge basalts
2014/4/8
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...
On the stability relations of hydrous minerals in water-undersaturated magmas
stability relations hydrous minerals water-undersaturated magmas
2012/4/1
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-

Synthesis, crystal structure, and phase relations of AlSiO3OH, a high-pressure hydrous phase
Synthesis crystal structure phase relations of AlSiO3OH high-pressure hydrous phase
2012/4/1
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...

Viscosity data for hydrous peraluminous granitic melts: Comparison with a metaluminous model
Viscosity data hydrous peraluminous granitic melts Comparison
2012/3/31
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...
