  1. The Crazy Mixed-Up Lunar Crust The lunar surface has 43 large, ancient impact basins that excavated and distributed a large amount of material across the entire Moon, affecting the geochemistry of the crust. http://www.psrd.hawaii.edu/Jan09/lunarBasins.html

  2. The Crazy Mixed-Up Lunar Crust Petro and Pieters mapped the horizontal and vertical distribution of well-mixed basin ejecta on a 1x1º global grid, showing contrasting patterns on the nearside versus farside. http://www.psrd.hawaii.edu/Jan09/lunarBasins.html

  3. The Crazy Mixed-Up Lunar Crust • PKT has the highest amount of deeply-mixed basin ejecta • FHT and SPAT received smaller amounts of shallowly-mixed ejecta from the 42 (post-SPA) basins • Surprisingly, geochemical signatures survived despite all the horizontal and vertical mixing of materials during the basin formation era early in lunar history The cumulative effects of basin formation directly influenced the observed geochemical terranes, outlined on the map. http://www.psrd.hawaii.edu/Jan09/lunarBasins.html
