Exposure ages and erosion rates for lunar rocksThe available data on the effects of particle bombardment of lunar rocks are examined, taking into account rare gas data, neutron capture products, radioactive nuclei, and particle tracks. Attention is given to exposure ages, questions concerning the validity of exposure ages, the location of rocks during irradiation, the criteria for valid crater ages, special problems regarding lunar breccias, surface residence times from long lived radioactive nuclei, surface residence times from galactic cosmic ray track data, rocks with simple surface exposure, rocks with complex surface exposure, limits on surface residence times, suntan and subdecimeter ages, erosion rates, and a number of case histories related to exposure age measurements as applied to the problem of the dating of impact events.
