Abstract: A series of hydrothermal experiments were performed to determine the phase relations on the beidellite-saponite pseudo-binary join. Quenched glasses with stoichiometric dehydrated compositio...
The phase relations at high pressure and high temperature for the FeTiO -MgTiO join were de-termined using several different experimental methods. Through a series of multi-anvil experiments,a phase ...
We report here an investigation of amphibole synthesis within the ternary system Ca Mg Si O (OH) - Mg Al Si O (OH) -Mg Si O (OH) (= TR-PG-MC) to define better the limits of solid solution for amphi...
Enthalpies of drop-solution (?H ) of a suite of stuffed quartz-derivative phases with the compo-drop-soln Al Si O (0 ? x ? 1) have been measured in molten 2PbO°§ O at 974 K. Substitution of sition...
