FIG. 5. — Olivine and Chassigny-like end-member (Fo₆₈) distributions. Data from the Mars Global Surveyor TES indicating olivine distribution (A) and details in Nili Fossae area of Chassigny martian meteorite-like olivine with molar ratio of Mg/Mg+Fe of 0.68 (designated as Fo₆₈). (A) Total mean surface-normalized abundance of olivine overlaid on MOLA global shaded relief map. (B) MOLA map of Nili Fossae area (yellows are highs, and blues are lows); rectangle is area shown in (C–E). (C–E) Fo₆₈ (Chassigny-like end-member) distribution, overlaid on MOLA topography. (C) Overlay is with 20% transparency (scale shows concentration of Fo₆₈, and vertical line in scale denotes the detection limits, with data interpolated to fill the map). (D) Overlay is with 60% transparency. (E) Overlay is with 80% transparency. Arrows in (C–E) point to the same location (with highest Fo₆₈ abundance). (A) Adapted from Koeppen and Hamilton (2008); (C–E) adapted from Hamilton et al. (2003).
