Two types of crystallization paths in iron oxide systems are illustrated by describing equilibrium crystallization in the fayalite field of the system FeO-Fe 2 O 3 -SiO 2 . In...

Unlike water vapor and F, carbon dioxide under pressure has little or no effect on the rates of melting or crystallization of granite or alkali feldspars, and the melting temperatures...

At 5,000 lbs./in. 2 of CO 2 , tilleyite is stable between 930 and 970 degrees C. and at 3,000 lbs./in. 2 of CO 2 , between 870 and 930...

The mineralogy of mottled limestones and associated dolostones of the Lower Ordovician Burchards limestone in W-central Vermont was quantitatively studied by X-ray diffraction. The dolomitic mottled patches consist of dolomite...
