... enriched in magmatic sulfur ( Thollot et al., 2012 ). The jarosite at Ophir Chasma occurs as layers along the canyon floor, pointing again to evaporating groundwater ( Wendt et al., 2011 ). In each of these cases, the jarosite is restricted to areas of natural groundwater emergence or pooling water...

We divide the sedimentary deposits in the Valles Marineris into those that have not been tectonically disrupted (deposits in Ophir, Melas, Juventae, and Ganges Chasmata) and those that have, like the west Candor Chasma deformed layered deposits ( Metz et al. 2010 , Okubo 2010 ). This work has...
