Mars Crustal Dichotomy: Large Lowland Impact Basins may have Formed in Pre-Thinned Crust
Author(s): Frey, H. V.
Abstract: Crater retention ages of large impact basins on Mars suggest most formed in a relatively short time, perhaps in less than 200 million years. Large basins in the lowlands have thinner central regions than similar size basins ...
