Figure F5. Comparison of mineral compositions between microgabbros and coarse-grained host gabbros. Except for plagioclase in Sample GS77-11, the compositions of the same minerals in the two groups are broadly similar, suggesting that there is a fairly good degree of compositional equilibrium between the two. Fo = fosterite, ol = olivine, cpx = clinopyroxene, An = anthorite.
