Subsurface Volume Loss and Collapse due to Surface Infiltration of Osuga Valles' Catastrophic Floods, Mars
Abstract
Osuga Valles form a distinctive catastrophic system in which the flood events can be tracked from its chaotic origin down to its sink at terminal depressions or cavi. We have begun analyzing Osuga's terminal cavi, centered around 14°50'S and 37°25'W, to understand the possible formation mechanism(s) of these depressions. The cavi's association with the outflow channels implies that there may be a link between the inflowing floodwater and the formation of the cavi, and hence the possibility of formation by surface collapse from subsurface dissolution processes, if such subsurface mineralogy existed.
