The South Pole-Aitken (SPA) basin is possibly the largest, oldest basin on the Moon. Since its formation the basin has undergone extensive modification events due largely to impacts and the limited emplacement of mare basalts. Nevertheless, albedo and geochemical data from Clementine and Lunar Prospector strongly suggest that the SPA interior contains distinct materials, which, due to the size of the basin, may be deep-seated in origin. Clearly, large and small craters have reworked materials within the basin and an unknown amount of exterior material has been transported into the basin. To confidently identify any material as representing deep-seated products requires an evaluation of the approximately 4Ga impact and resurfacing record. In order to identify likely components of the original SPA melt breccia and/or deep-seated material requires recognizing areas that have undergone minimum reprocessing by large craters, basins, and volcanism and the ability to reconstruct local stratigraphy.
