An investigation was made of chemical variation within garnet, chlorite, and plagioclase in the metamorphosed Standing Pond amphibolite of the Hanover quadrangle, New Hampshire-Vermont. The mineral assemblages epidoteplagioclase, sphene-rutile, ilmenite-rutile, garnet-rutile- ilmenite, and kyanite-muscovite are also discussed. Little correlation was round between metamorphic zone, ironmagnesium ratios and calcium and manganese content of the various minerals. The theoretical grounds for such correlation are discussed, and it is concluded that the apparent metamorphic grade fluctuates within zones because of minor differences in temperature-pressure conditions and bulk composition.
