Mars high resolution gravity fields from MRO, Mars seasonal gravity, and other dynamical parameters (2011, background): “For example, if we fix DT = 200K and crustal thickness to 50 km (cf. Zuber et al., 2000; Nimmo, 2002; Wieczorek and Zuber, 2004), then the allowed range in vM which satisfies both constraints is only about 84–86%.”
The composition of Mars (2019, background): “The average crustal thickness of 50 km, which is consistent with geophysical and geochemical constraints (Zuber et al., 2000; McGovern et al., 2002, 2004; Wieczorek and Zuber, 2004; Ruiz et al., 2009), is adopted in the modeling.”
Bulk composition and early differentiation of Mars (2007, background): “If the crust is 57 km thick, as inferred from geophysical studies [e.g., Wieczorek and Zuber, 2004 ], then 50% of the bulk Th is in the crust.”
The bulk composition of Mars (2013, background): “Since the crust averges 57 km thick (Wieczorek and Zuber, 2004), making up about .6 wt% of bulk silicate Mars, its mean Cl content should be around 50 ppm. GRS and MER data show that the average surface Cl conentration is about 5000 ppm.”
EARLY CRUSTAL EVOLUTION OF MARS 1 (2005, methodology): “Wieczorek & Zuber (2004) showed that this approach introduces errors, and they derived a mean crustal thickness for the southern highlands of 57 ± 24 km. Crustal thicknesses have also been estimated using geochemical data (see Chemical Characteristics, below).”
Degree-1 convection in the Martian mantle and the origin of the hemispheric dichotomy (2006, background): “However, Zhong and Zuber [2001] considered a low value for activation volume relative to what the Earth’s mantle is expected to have [Karato and Jung, 2003].”
Enceladus's and Dione's floating ice shells supported by minimum stress isostasy (2016, background): “Finally, isostasy plays a crucial role in understanding the long-wavelength gravity and shape as well as estimating the crust thickness of the planets Mars [Wieczorek and Zuber, 2004], Venus [James et al., 2013], and Mercury [Perry et al., 2015].”
Crustal structure of Mars from gravity and topography (2004, methodology): “Wieczorek and Zuber [2004] advocate a plausible range of bulk crustal densities from 2700 to 3100 kg m� 3. Following many authors, we adopt 2900 kg m� 3 as a Bouguer reduction density.”
Constraints on the Martian lithosphere from gravity and topography data and implication for volcanism and possible mantle heterogeneities (2005, background): “Assuming an average crustal thickness between 38 and 62 km [ Wieczorek and Zuber, 2004 ], the 6 km dierence in elevation between the Northern lowlands and Southern highlands would correspond to a dierence in density between 310 and 520 kg m 3. Though slightly on the high side, this number is roughly”
Experimental petrology of the basaltic shergottite Yamato‐980459: Implications for the thermal structure of the Martian mantle (2006, result): “In these models, the crust is assumed to be 53 km in thickness (the top four rows of the finite element grid), consistent with the results of Wieczorek and Zuber (2004).”
Heterogeneous distribution of H2O in the Martian interior: Implications for the abundance of H2O in depleted and enriched mantle sources (2016, methodology): “In order to compute the estimates, we use (1) a crustal thickness estimate of 57 km (Wieczorek and Zuber 2004), (2) a core radius of 1680 km (Taylor 2013), (3) an average crustal density of 2900 kg m 3 (Neumann et al. 2004), and an average mantle density of 3400 kg m 3 (Bertka and Fei 1997).”
