Scientific paper

Results are presented from SIMS analyses of major, minor, and trace elements in lunar picritic glass beads obtained from the Apollo 14 (A-14) and Apollo 17 (A-17) landing sites. The results obtained indicate that the glasses from each site differed significantly in their Ba/Sr and light-REE/heavy-REE ratios. The differences between the A-14 and the A-17 glasses appear to be the result of a higher KREEP component in all the A-14 glasses, indicating that the mantle source of the A-14 site is intrinsically different from the A-17 mantle source.
