Iron silicate equilibria in the Cape Smith Belt, New Quebec.

By Tsutomu. Hashimoto


This thesis is a study of phase equilibria among iron-rich silicate minerals in the metamorphic iron formations in the Cape Smith Belt, New Quebec, and is based on the chemical analyses of eight iron-rich silicate minerals. Mineral assemblages investigated include: grunerite-stilpnomelane, grunerite-stilpnomelane-almandite-biotite, stilpnomelane-minnesotaite-iron chlorite, all with quartz, magnetite, and calcite. Their stability relationships in the system FeO-MgO-Fe203-Al203-Si02-H20, during metamorphism are discussed
