Description:
The characteristics of 28 regolith breccias returned from the Apollo 15 site have been compared with those of Apollo 15 soils, Apollo 15 rock types, and Apollo 16 regolith breccias. The results suggest that KREEP basalts are not exotic to the site, and that the site is underlain by KREEP basalts which were converted to a KREEP-rich regolith full of small KREEP basalt fragments and KREEP composition glass. A possible implication of the present model is that agglutinate production was not significant in the time interval from 3.9-3.3 Gy.
