Twelve clasts were separated from breccia 14304 for consortium study: six pristine highlands rocks, two mare basalts, and four nonpristine highlands rocks. The pristine highlands rocks include representatives of the magnesian troctolite-anorthosite and alkali suites, the two most common subgroups of the Mg suite found at the Apollo 14 site. Two troctolite clasts have olivine (~Fo 90) and plagioclase (~An 94) compositions similar to one group of Apolo 14 troctolites. One also contains spinel (Mg' 66--85). Incompatible element abundances in one are similar to those of 14305 troctolites, although the HREE (heavy rare earth elements) pattern is distinct among Apollo 14 troctolites. A dunite clast (~Fo 89) may be an unrepresentative piece of a troctolite. Alkali lithologies include an alkali anorthosite and an alkali norite, which is a rock type not previously described. The alkali norite has a pristine igneous texture and contains inverted pigeonite (Mg' 64), plagioclase (An82), K-feldspar, ternary feldspar, REE-rich phosphates, and silica. It resembles alkali gabbronorites from Apollo 14 and 67975 in mineralogy and mineral compositions. Alkali lithologies and phosphate-bearing magnesian anorthosites from Apollo 14 may have formed from Mg-rich magmas that assimilated various amounts of material rich in P and REE. This material could be a fractionated derivative of urKREEP. another pristine clast from 14304 is an Mg-gabbronorite. The two mare basalt clasts are very high potassium (VHK) basalts. They have 4 mg/g K and K/La ratios of 580 and 700. The parent magmas of VHK basalts could have formed from typical low-Ti, high-Al basaltic magmas by assimilation of K-rich material. This material could also be a fractionated derivative or urKREEP. Nonpristine 14304 clasts include melt-textured anorthosites and an augite-rich poikilitic melt rock. The latter is probably polymict, but its major component must be an Mg-suite gabbro.
