Formation of agglutinate-like particles in an experimental regolithAgglutinate-like particles composed predominantly of glass were produced from a fragmental gabbro target that was repetitively impacted by Ni-alloy projectiles. The experimental glasses are much more heterogeneous in composition than their lunar counterparts, and they are dominated by incomplete mixing of melted component minerals and by plagioclase-rich compositions. Most of the particles are found to be highly enriched in feldspar and to be sustantially fractionated relative to the initial bulk target. It is suggested that fractionation trends within lunar agglutinitic glasses may be partly due to phase-specific melting.
