Gaillard F.; Pichavant M.; Scaillet B. (2003)The critical role of iron on crystal-silicate liquid relationships and melt differentiation is mainly controlled by the redox conditions prevailing in magmas, but the presently available database merely constrains the ...
-
Gaillard F.; Scaillet B.; Pichavant M. (2002)The kinetics of Fe oxidation-reduction in two hydrous rhyolitic melts, one metaluminous and the other peralkaline, have been studied at 800 °C, 2kb, for melt water contents from ~5 wt% to saturation and fO2 between NNO-2 ...

LABORATORY MEASUREMENTS OF ELECTRICAL CONDUCTIVITY OF HYDROUS AND DRY SILICIC MELTS UNDER PRESSURE Gaillard F. (2004)An interpretation of the electrical signature of molten rocks within the Earth's interior in terms of nature and temperature conditions of magma requires additional laboratory data on the electrical conductivity of silicate ...

Gaillard F.; Schmidt B.; Mackwell S.; McCammon C. (2003)A kinetic model for the rate of iron-hydrogen redox exchange in silicate glasses and melts has been derived from time-series experiments performed on natural rhyolitic obsidians. Cylinders of the starting glasses were ...

Gaillard F.; Scaillet B.; Pichavant M.; Beny J.M. (2001)New experiments on the effect of dissolved water on the ferric-ferrous ratio of silicic melts have been performed at 200 MPa, between 800°C and 1000°C and for fO2 between NNO-1.35 and NNO+6.6. Water-saturated conditions ...
