Description/Abstract | Phase relations of pumpellyite, epidote, lawsonite, CaCO/sub 3/, paragonite, actinolite, crossite and iron oxide are analyzed on an Al--Ca--Fe/sup 3 +/ diagram in which all minerals are projected from quartz, albite or jadeite, chlorite and fluid.^Fe/sup 2 +/ and Mg are treated as a single component because variation in Fe/sup 2 +//Mg has little effect on the stability of phases on the diagram.^Comparison of assemblages in the Franciscan, Shuksan, Sanbagawa, New Caledonia, Southern Italian, and Otago metamorphic terranes reveals several reactions, useful for construction of a petrogenetic grid.^The relative P-T stability of the reactant and product assemblages can be determined on the basis of their field distribution and the occurrence of associated calcite or aragonite and jadeite or albite. |
