A single fragment from an Apollo 16 soil appears to be a soil agglutinate that has experienced thermal metamorphism. Its texture is similar to that observed in many of the samples of recrystallized polymict breccias collected in the lunar highlands. Debris blankets, consisting largely of mineral and lithic clasts and derived from highland bedrock by major impacts, are less likely than agglutinate‐rich soil from the highland megaregolith to be the progenitor of this class of recrystallized rocks.
