Abstract
The effects of heterogeneities in CTE and elastic parameters are particularly noticeable in Archean lithosphere, where difference in predicted elevations and geoid heights can reach values of â¥300 and â¼6 m, respectively, when compared to standard models. These effects are less (â²40 and 0.25 m, respectively) in Phanerozoic continental and oceanic lithospheres. Uncertainties in experimental data and geotherms indicate that compositional effects cannot be completely resolved by seismic tomography in regions with P-wave and S-wave anomalies â²Â±1.5 and ±3%, respectively.
