... for compositions QUE 94201 and Y 980459 (Y98). Results are shown for augite (QUE 94201 composition with Wo = 33 mol%), pigeonite (QUE 94201 composition with Wo = 13 mol%), and orthopyroxene (Y98 composition with Wo <4 mol%). Olivine is also shown for comparison. In all cases, the error bars represent the 1σ...

... on the same bulk composition as the natural sample; and (3) that bulk composition represents a melt from the martian mantle, so an accurate D Cr and D V are measured. Presently, the two best candidates for martian melts, Y 980459 and QUE 94201, indicate an f O 2 of IW to IW+1 for the upper martian mantle...

... basalts. Shergottites Yamato 980459 (Y 980459) and NWA 5789 are not elevated in the SiO 2 activity proxy, but experiments suggest that the Y 980459 parental magma could have been hydrous ( Draper, 2007 ), and both are elevated in XSiO 2 ( Gross et al., 2011 ). To strengthen this argument, we used...
