Pb-204, Bi, Tl, and Zn have been measured in Apollo 16 samples and Apollo 17 orange soil. These data in addition to already reported Apollo 14 and 15 Pb-204 results and literature data are used to support the Pb-204-metallic phase coherence. The partition of Pb-204 into very fine metallic grains appears to be the result of an impact process rather than metal segregation in a magma.
