Abstract

Re-examination of a vast amount of lead and xenon isotope data that have been accumulated since the Apollo 11 landing on the moon in July 1969 reveals that some of the lunar fines and breccia started to retain their radiogenic lead and fissiogenic xenon isotopes about 5 billion years ago when the ratios of235U and244Pu to238U in the early solar system were approximately 4 and 2 atoms per 10 atoms of238U, respectively.
