This map of the iron concentration of the Apollo 16 landing site was derived from the Clementine color data presented in slides #14 and #15. The iron concentrations are shown by color, and the map data are overlaid on the Apollo 16 metric image shown earlier (slide #13). Note that the Cayley plains show iron concentrations of between 4 and 6 wt%, which is in line with the values determined for Apollo 16 soil samples. The rugged Descartes highlands show areas with slightly less iron content, from 2 to 6 wt%. Iron values were determined using the technique of Lucey et al. (1995). Right
