Spectral and photogeologic mapping of Schrödinger Basin and implications for post-South Pole-Aitken impact deep subsurface stratigraphy

► We mapped the Schrödinger region using LROC and M3. ► The region provides a cross-section of the lunar crust. ► The peak ring is composed of massive blocks of lunar magma ocean cumulates. ► The peak ring is compositionally and texturally distinct from the ejecta blanket.
