Pre-tectonic oceanic plateau?

Filed under: Letters from Ionia — Tags: , — zankaon @ 12:32 am

Was there oceanic plateau formation for before plate tectonics era? Perhaps later, plateau gave rise to terranes along west coast of nearer equatorial positioned N. America. Might Mars serve as a model of what pre-tectonic earth  era looked like? Are there plateau on Mars? If not, would this then be consistent with such plateau formation for after commencement of plate tectonics? Might plate tectonics have started in middle or later Archean (1-2 Byrs after origin) for Earth? TMM
