Description
Summary:We provide the first detailed 1:100,000 scale geomorphologic map of the ~100 km Amundsen crater region, which is of high scientific relevance for future exploration, e.g., NASA's VIPER mission, the Artemis program, and the Chinese International Lunar Research Station (ILRS). We investigated the complex geological history of the region before and after the formation of Amundsen crater on the rims of the South Pole-Aitken (SPA) and Amundsen-Ganswindt basins. We present a new Amundsen crater formation age of ~4.04 Ga, which, in contrast to previously derived ages, is based on non-light plains terrain. The estimated maximum excavation depth for Amundsen crater is ~8 km, and elevated concentrations of FeO near the crater suggest that Amundsen may have redistributed SPA-derived materials. Plains materials of various kinds were observed both inside and outside Amundsen crater and are estimated to be up to 350 m thick and ~3.8 Ga old. A less cratered, tens of meters thick, mantling unit indicates a resurfacing event ... : Mapping Scale is 1:100,000. Digitization scale is 1:1M. ...
