Provenance of Apollo 12 KREEP.Possible origins of KREEP in Apollo 12 lunar samples are evaluated in terms of their probabilities. Preference is given to the assumption that the KREEP may be a mixture of roughly equal proportions of (1) ejecta from Copernicus, (2) ejecta from Reinhold, (3) ejecta from local highlands, and (4) material excavated from Fra Mauro deposits buried below the landing site.
