List of orthopyroxene minerals
WebAbstract. An internally consistent set of standard state and mixing properties has been derived for olivine, orthopyroxene, garnet, cordierite, and ilmenite in the system FeO-MgO-CaO-Al 2 O 3 -TiO 2 -SiO 2 -H 2 O from analysis of relevant phase equilibrium and thermophysical data.
