Mars’ pre-tectonic model?

Filed under: Letters from Ionia — Tags: , — zankaon @ 7:42 pm

Might Mars serve as a pre-tectonic model for Earth? For example, no continents, no mountain building nor deep oceans? And does homogeneity of Valles Marineris, as opposed to Grand Canyon, suggest homogeneity for Earth’s pre-tectonic environment? Might recent ‘footprint’ analysis by Curiosity indicating feldspar (?), olivine etc., suggest more of a cooled mantle, rather than any crust? Thus does the homogeneity of Valles Marineris then suggest just a cooled mantle? TMM
