Samples
editLunar sample 12004, an olivine basalt, was collected at the rim of Middle Crescent.[2] Samples 12014, 12015, and 12016 were probably collected there, but the provenance is less certain. 12014 is also an olivine basalt.[3] 12015 is an olivine vitrophyre.[4] 12016 is an ilmenite basalt.[5]
