| Description | New radiometrically determined ages of Martian meteorites add to the growing number with crystallization ages <~ 1.4 Ga. The observation of mainly geologically young ages for the Martian meteorites, the only exception being the ~4.5 Ga ALH84001 [1], is paradoxical when viewed in context of a Martian surface thought to be mostly much older as inferred from the surface density of meteorite craters [2]. There appears to be at least a twofold difference between the observed ages of Martian meteorites and their expected ages as inferred from the ages of Martian surfaces obtained from crater densities. |
