| 内容記述 | Cosmic ray exposure data for Apollo 17 samples and quantitative photogeologic data are presented which support the hypothesis that the Central Cluster unit and the Bright Mantle at the Apollo 17 landing site are related to impact of ejecta from the crater Tycho, lying about 2000 km to the southwest. The exposure ages point to a site-wide event 96 m.y ago, which included emplacement of the Bright Mantle and Central Cluster units. |
