Preliminary report of mineralogical and petrographic study of the Luna 16 lunar surface material sample
Abstract
Unsorted powder and grains larger than 0.5 mm from the L-16-19-118 lunar sample consisted of eight basaltic fragments, four fragments of breccias (of which one was quite light), one white grain (maskelynite), one chondrule, and slagged dark partially glassy chunks. The mineralogical composition of all rounded particles led to the assumption that they are all of lunar origin; but their presence in the regolith indicates formation of chondrulic meteorites. The existence of several grains of pyroxene coated with a thin glassy film merits attention.
