EARLY CRUSTAL EVOLUTION OF MARS 1 (2005, background): “Both Zuber et al. (2000) and Nimmo & Stevenson (2001) argued that crustal thicknesses in excess of ∼100 km would lead to the destruction of lateral crustal thickness variations by lower crustal flow, giving an upper limit on crustal thickness.”
Correction to “Localized gravity/topography admittance and correlation spectra on Mars: Implications for regional and global evolution” (2004, background): “The average crustal thickness for the Hellas region is unlikely to be as great as 100 km, however, on the basis of the argument that temperatures near the base of such thick crust would lower the effective viscosity to the point that lower crustal flow would remove lateral variations in crustal thic”
Degree-1 convection in the Martian mantle and the origin of the hemispheric dichotomy (2006, background): “[19] Although plate tectonic-style mantle convection has been suggested for early Mars [Sleep, 1994; Nimmo and Stevenson, 2001; Lenardic et al., 2004], in this study we only considered stagnant-lid convection which is realized through either depth-dependent or temperature-dependent viscosity.”
Localized gravity/topography admittance and correlation spectra on Mars: Implications for regional and global evolution (2002, background): “Further, topographic relaxation arguments suggest that values of T cr > 100 km are unlikely [Zuber et al., 2000; Nimmo and Stevenson, 2001].”
Crustal structure of Mars from gravity and topography (2004, background): “Viscous relaxation arguments [Zuber et al., 2000; Nimmo and Stevenson, 2001] suggest that 50–100 km is the maximum thickness that could maintain hemispheric crustal variations against channel flow over Martian history.”
Thickness of the Martian crust: Improved constraints from geoid-to-topography ratios (2004, methodology): “Furthermore, our maximum value of 81 km is less than the maximum allowable value of 115 km based on the viscous relaxation study of Nimmo and Stevenson [2001] , as well as the 93-km maximum value obtained from thorium mass balance considerations.”
Gravity and Topography of the Terrestrial Planets (2015, result): “This range of values is consistent with estimates based upon the viscous relaxation of topography (Nimmo and Stevenson 2001; Zuber et al. 2000a) and geochemical mass-balance arguements, both of which require the crust to be less than ∼100 km thick (see Wieczorek and Zuber 2004).”
