A KREEP-rich fragment-laden melt series in the Apollo 14 white rocks is interpreted to be the result of impact into a source region possibly consisting of KREEP volcanic rock flows, underlain and surrounded by anorthositic-troctolitic highlands rocks. The melt groundmass is a high-alumina, high-K2O Fra Mauro basalt, enriched in plagioclase. A poikilitic texture is developed in the coarser members of the series, possibly as a result of the impact melt being seeded with relict plagioclase nuclei.
