DAG has some interesting terrestrially-old and visually still nice meteorites where weathering was/is very slow. This W3 LL example shows that. The sentence below is from an abstract on the DAG meteorite area: "The existence of meteorites in the DAG area is the result of a combination of specific geological and geomorphological conditions: there is a bright-colored, old limestone plateau (*2 Ma), under arid weather conditions over long periods of time, with rapid elimination of surface water if present and low erosion rates". |
