6. Mixing Process of the Lunar Surface Materials and their Cosmic-Ray Exposure Age
Published online by Cambridge University Press: 12 April 2016
Abstract
From the cosmic ray exposure age data, (time scale 107 - 108 years), of the lunar surface materials, we discuss the mixing process of the lunar surface layer caused by the meteoroid impact cratering. The gardening effect calculated using a crater formation rate slightly modified from the current population data is consistent with observed exposure ages of the lunar samples.
