Diogenite exposure ages
Abstract
He, Ne and Ar isotopes have been measured in six, and Al-26 in two diogenites. Cosmic-ray exposure ages corrected for shielding effects using Ne-22/Ne-21 ratios are generally concordant. Five diogenites have a group age of 14 Myr and three others may have a group age of 24 Myr, implying that two collisions may have produced 8 of the 9 diogenites.
