25Mg NMR spectra for several silicate and aluminosilicate melts were obtained from 1000–1470 8C. The peaks are initially very broad, but narrow with increasing temperature to near 500 Hz at the highes...
The shear viscosities of melts in the system Na-Fe-Si-O-F-Cl were determined over a wide range of temperatures (400–1200 8 C) at 1 atm pressure in air. The compositions are based on the addition of Fe...
Algorithmic modifications to the MELTS software package are presented in order that calculations of heterogeneous phase equilibria can be performed in the subsolidus. Methods are presented for: (1) se...
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...

Anovel type ofhigh-temperature, high-pressure cell has been designed for near-infrared and optical spectroscopy of hydrous silicate meltsat pressures up to 3 kbar and temper-atures up to 800 0c. It co...
In situ, high-temperature Raman spectroscopy of Na,O.9SiO, glasses and melts with and without 2 mol% P,05 has been conducted to 1491 K (near the liquidus temperature). In the temperature range from 29...
