We presented petrological maps of four interesting craters, namely Alder, Antoniadi, Dryden, and Lyman. All craters show an increased Mg-rich rock content in the central peak region and the crater rims. More important, the craters Alder, Antoniadi, and Dryden show structures containing high abundances of anorthosite on the crater rim indicating geologically interesting events. We will include morpho-logic data into future studies to further analyze these interesting structures.
