Abstract
We present here experimental data on the depth variation of fossil-track densities in the hypersthene and oligoclase crystals sampled from several cores taken from the least ablated regions of the meteorite Saint-Séverin. The implications of these results (and of those in the Patwar meteorite) to the extent of atmospheric/preatmospheric ablation, and to the time-averaged flux and energy spectrum of cosmic-ray iron-group nuclei during the last 10–50 × 106 years, are discussed.
