Possible REE anomalies of Apollo 17 REE patterns.
Abstract
Six Apollo 17 samples were analyzed for the rare-earth elements and Ba. It is pointed out that the 'liquid-type' lunar materials show the positive Ce anomaly, while the 'solid-type' lunar materials do not show the corresponding effect. These results from the Apollo 17 analyses are in agreement with Nakamura's (1974a) recent observation about the Ce anomaly.
