Bulk APXS chemistry for select elements of all Gale unconsolidated targets, as well as average soils from the Mars Exploration Rover Spirit and Opportunity sites [Morris et al., 2006a, 2006b] normalized to Portage at Rocknest. Soils in the vicinity of Rocknest, High Dune, and Namib dune are indicated by colors. For Rocknest, the order of targets is unscuffed, scuffed, and Portage; note that high temperatures and large standoff distances degrade the quality of the first two samples. For High dune, the order of targets displayed is Warsaw, Weissrand, Kibnas, and Barby. For Namib dune, the order of targets displayed is scuff, scoop2, and discard piles A, D, C, B, C2, E, and F. Target details by number are in Table 3.
