Description:
It is shown that lunar rock 72315, because of its brief surface exposure age and a geometry which minimizes corrosion, makes it possible to obtain a virtually uneroded Fe spectrum, averaged over several hundred thousand years. The absolute exposure age of the rock is determined by taking into account the intensity of solar flares and galactic cosmic rays. The galactic cosmic ray production spectrum reported by Walker and Yuhas (1973) is used in the determination of the exposure age.
