... along the forsterite-brucite join in the MgO-SiO 2 -H 2 O (MSH) system contain several hydrated phases, including hydroxylclinohumite, hydroxylchondrodite, and the DHMS phase A. With the inherent difficulties in synthesizing hydrous phases and elucidating consistent phase boundaries in the MSH system...

... modeling in the CaO-MgO-Al 2 O 3 -SiO 2 -H 2 O-CO 2 (CMASV) system indicate that the presence of Ti and F in H 2 O-rich fluids facilitated the formation of clinohumite, which in turn indicates that the presence of F in the H 2 O-rich fluids must have enhanced Ti mobility, as the solubility of Ti (or TiO 2...

... be interpreted in terms of a rotation of the OD vector and a reduction in the degree of static disorder associated with the hydrogen bond acceptor/donor site. These new crystallographic data are discussed in terms of corresponding spectroscopic measurements reported recently in the literature. Within the MgO...

... the effects of composition on the elasticity and sound velocities of minerals along the forsterite-brucite join in the MgO-SiO 2 -H 2 O system, confirming previous observations. Increasing H 2 O content along the forsterite-brucite join leads to apparent reductions in the elasticity and sound velocities...

.... Phase relations in the system CaO–CO 2 and MgO–CO 2 ( Huang and Wyllie, 1976 ). At high pressures and temperatures, CaCO 3 and MgCO 3 decomposition curves are bounded by points Q 1 and Q 2, respectively. At higher pressures and temperatures, calcite and magnesite melt incongruently: Cal(CaCO 3...
