Mineralogy of a basaltic clast, Ba-2, found on the cut surface of a new slab of lunar highland regolith breccia 60019 was studied and compared with that of lunar meteorites ALHA81005 and Y791197. The coarse-grained Ba-2 clast consists of Na-bearing plagioclase, high-Ca clinopyroxene, ilmenite, silica, and mesostasis. The mineralogy and chemical zoning trends in the Ba-2 clast suggest that this basalt is similar to the 60639,1 basalt in the Apollo 16 rake samples, and to Luna 16 high-alumina moderate-TiO2 mare basalts; however, olivine is not present in Ba-2. On the basis of these and other findings, and assuming the early formation of the Apollo 16 regolith breccia (as proposed by McKay et al., 1986), it is suggested that B-2 could represent a post-Nectaris lava flow older than the formation of 60019.
