Extended Data Fig. 2: Topography and crustal structure around Utopia Planitia.
From: A thick crustal block revealed by reconstructions of early Mars highlands
a, MOLA topography of Mars (ref. 9). b, crustal thickness of Mars (ref.17). In a–b, the maps are in Lambert azimuthal equal-area projection, centred on Utopia Planitia. Each map covers all of Mars except for a small region antipodal to the map centre. Maps are draped over present-day topography for reference. c, radial profiles of surface and mantle topography measured from the centre of Utopia. d, radial profiles of crustal thickness. In c–d, each coloured line represented a different radial profile, coloured by the azimuth of that profile. The white lines are the mean of the surface and mantle topography profiles.
