Rift Processes at Valles Marineris, Mars: Rate Dependent Strength Evolution Versus Necking
Abstract
Analytical models for extensional processes that either incorporate the evolution of lithospheric strength as a function of time or are based on the necking instabilities are presently applied to Valles Marineris, comparing the lithospheric structure predicted by each model as being necessary for the formation of the observed troughs. It is noted that the strength-evolution models are not fully 2D, while necking models do not address the evolution of the geotherm with time and finite extension.
