Figure 4. Topographic map of Mars from the MGS MOLA investigation with contours of constant radial magnetic field (black:negative, white:positive) as in Fig. 1. Elevation relative to a reference surface (yellow) range up to 8 km negative (yellow, green, light blue, dark blue) and 8 km positive (yellow, red, white). Crustal magnetization appears largely confined to the ancient southern highlands. Regions of extensive volcanism (e.g., Olympus Mons, Tharsis Montes) are non-magnetic as are regions surrounding the large impact basins Hellas and Argyre.
