“…Other components that appear to be similar to this group in age, but preserve their igneous textures, include fragments of anorthosite, olivine breccia, mare basalt, and rhyolite glass. This compositional variety of fragments forms clasts in texturally later microbreccia-2 and 3 (Duncan et al, 1975b). Microbreccias 2 and 3 together with anorthosite clasts and fragments of basalt, which are compositionally different from the basalts included in microbreccia-1, bind with the matrix to form sample 14321.…”
