57-63

Plots of specific gravity, state of order as inferred from X-ray powder films, and anorthite content of 43 plagioclases from anorthositic rocks and in the composition range An42-62.5 indicate that in this composition range relatively disordered plagioclases of a given anorthite content have Iower specific gravities than do relatively ordered plagioclases of the same composition.
