Bulk compositionspetrology and mineralogy of > 0.5 mm Luna 16 aluminous mare basalt particles are described. The data rule out any close genetic relationships between Luna 16 and other major types of lunar mare basalts. Compared to high‐Ti mare basaltsthe Luna 16 basalts contain lower TiO 2 (5.1 wt %) and Ta (∼ 0.8 ppm) and higher Al 2 O 3 (13.3 wt %) and REE (∼ 30‐70X chondrites) abundancessuggesting that the Luna 16 source rocks crystallized later than (i.e. stratigraphically above) the ilmenite‐bearing high‐Ti basalt cumulate source rocks. The REE pattern for the Luna 16 basalts requires that the source material from which they were derived crystallized from a light REE enriched magma.
