- Abstract
The South Pole-Aitken Basin (SPA) is located on the lunar farside, centered at ~53° S, 191° E. It is the oldest [1,2] and largest lunar basin [3-6]. Understanding the geological units and stratigraphy related to the SPA basin is fundamental for the interpretation of the history and evolution of the Moon, as well as for investigating the geological environment at the South Pole for future exploration. Our new map is an extension of the Apollo basin map [7], and includes parts of Orientale basin and the South Pole to provide a comprehensive view of the regional geology. First we defined units and features on the basis of geomorphology and albedo, mainly on Lunar Reconnaissance Orbiter [8,9] and Kaguya [10] data at a scale of 1:500000. In a second step, we used crater size-frequency distribution measurements [e.g.,11] to compile an absolute stratigraphy of the units in the region.
