Abundances of O, Si, Al, and Mn determined in a Luna 20 fines sample by instrumental neutron activation analysis are presented and compared with those found in Apollo lunar soil samples. The results obtained include the finding that O/Si ratios exhibit very little variability among fines samples from various lunar landing sites, whereas the Al/Si ratio is highly variable.
