Calculation and application of clinopyroxene-garnet-plagioclase-quartz geobarometers
(Springer-Verlag, 1988-09)
Recently published thermodynamic and experimental data in a variety of chemical systems have been evaluated to derive Gibbs free energies for hedenbergite and pyrope. These were used to calculate the geobarometric equilibria
Phlogopite-chlorite reaction mechanisms and physical conditions during retrograde reactions in the Marble Formation, Franklin, New Jersey
(Springer-Verlag, 1984-12)
A retrograde assemblage in a specimen from the Franklin Marble Formation containing an unusual occurrence of three micas has been studied. Microprobe analyses of the margarite, muscovite and phlogopite reveal significant ...
Heat capacity measurements for cryolite (Na3AlF6) and reactions in the system Na---Fe---Al---Si---O---F
(Elsevier, 1987-12)
The heat capacity of cryolite (Na3AlF6) has been measured from 7 to 1000 K by low-temperature adiabatic and high-temperature differential scanning calorimetry. Low-temperature data were obtained on material from the same ...
Heat capacity and phase equilibria of almandine, Fe3Al2Si3O12
(Elsevier, 1993-09)
The heat capacity of a synthetic almandine, Fe3Al2Si3O12, was measured from 6 to 350 K using equilibrium, intermittent-heating quasi-adiabatic calorimetry and from 420 to 1000 K using differential scanning calorimetry. ...
The heat capacity of a natural monticellite and phase equilibria in the system CaO-MgO-SiO2-CO2
(Elsevier, 1986-07)
The heat capacity of a natural monticellite (Ca1.00Mg.09Fe.91Mn.01Si0.99O3.99) measured between 9.6 and 343 K using intermittent-heating, adiabatic calorimetry yields Cp0(298) and S2980 of 123.64 +/- 0.18 and 109.44 +/- ...
The heat-capacity of ilmenite and phase equilibria in the system Fe-T-O
(Elsevier, 1985-10)
Low temperature adiabatic calorimetry and high temperature differential scanning calorimetry have been used to measure the heat-capacity of ilmenite (FeTiO3) from 5 to 1000 K. These measurements yield S2980 = 108.9 J/(mol ...
