In fine (type A) and coarse-grained (type B) Apollo 11 lunar volcanic rocks clinopyroxenes are extremely inhomogeneous. Ferrosilite-rich areas in type B rocks have decomposed to submicron vermicular intergrowths of clinopyroxene-fayalite-cristobalite(?). Plagioclase has normal zoning with K2O up to 0.5 percent in rims. Ilmenites are relatively homogeneous with low MgO (0.1 to 2 percent) and high ZrO2 (up to 0.26 percent). Metal phase in troilite has <0.02 percent nickel. The breccias (type C) and fines (type D) contain similar phases and aggregates of types A and B together with glassy spherules containing 0.09 to 10.52 percent TiO2. Rare metal fragments with meteorite-like compositions occur in breccias and fines. Gross similarities between eucrites and Apollo 11 volcanic rocks indicate similar evolutionary environments, but detailed mineralogical differences suggest either separate origins or, if eucrites are lunar, chemical inhomogeneities on the lunar surface.
