Scientific paper

A search for siderophile superheavy elements (SHE) in metal fragments within ordinary chondrites is described. The absence of excesses of tracks along the boundaries between olivines and metal grains allows upper limits to the SHE content of the metal of about 2.5 X 10 to the -13 to about 2.5 x 10 to the -15 kg per kg to be set at a time approximately four billon years ago, determined from the Pu-244 fission track densities in chondritic phosphates. Unless the metal of the lunar core was very much enriched in siderophiles relative to meteorites, SHE could not have played an important role in the early heating of the moon.
