Luna 16 - Relative proportions and petrologic significance of particles in the soil from Mare Fecunditatis.

Some 2380 lithic and vitreous particles from levels A and G of the Luna 16 core-tube sample were classified. The relative proportions of particle types from each of the two layers are reported, and some petrological and mineralogical aspects of the lithic and vitreous components of the lunar regolith are discussed. Possible sources of the particles in the Luna 16 soil are examined.

Mineralogy, petrology, and chemistry of a Luna 16 basaltic fragment, sample B-1.

Petrological, mineralogical, and chemical investigations of the B-1 Luna 16 sample have revealed that the sample is a fine-grained ophitic basalt which is distinguished from the Apollo samples by containing a single pyroxene, an ilmenite content intermediate to that of the Apollo samples, and subequal amounts of pyroxene and plagioclase. It is also distinguished by a high Sr content and a high K/U value.
