Chemical dispersion among Apollo 15 olivine-normative mare basalts.
Abstract
New analyses of Apollo 15 olivine-normative mare basalts for major and minor elements combined with a synthesis of all published data for them provide no support for the hypothesis that the coarser-grained varieties (olivine microgabbros) consist of two chemical groups. Instead, analyses of the coarse and fine basalts are consistent with their being a single group.
