Geologic Mapping and Drainage Basin Analysis in Margaritifer Sinus, Mars

The Margaritifer Sinus region within the cratered highlands of Mars is located near the eastern end of Valles Marineris and approximately 1000 km northeast of Argyre Planitia. In an attempt to refine the understanding of the evolution of valley and channel networks in and near southeastern Margaritifer Sinus (MC19SE), drainage basin mapping is being undertaken as part of a NASA-funded effort to systematically map Mars MTM quadrants -10022, -15022, -20012, and -25012. Efforts involve detailed geologic mapping and evaluation of drainage morphometry in topographically defined basins. The goal is to better define the timing, processes, and geomorphic thresholds contributing to the formation of these enigmatic drainage features.
