Emplacement of a Debris Ocean on Mars by Regional-Scale Collapse and Flow at the Crustal Dichotomy

Giant debris flows could have filled the northern lowlands with approx. 2 km of sediment in 10(exp 3) to 10(exp 5) years by catastrophic regional terrain collapse. The outburst floods and chaos zones are probably the waning stage of this process. Additional information is contained in the original extended abstract.
