Sulfates in Valles Marineris and Implications for Mars' Aqueous History
Introduction: Mapping the type and distribution of hydrated mineralogy is one way to track the aqueous history of Mars. Sulfates are a potentially good tracer of past climate because they form by aqueous processes , so their presence, volume, and process of formation can characterize how much water was available. The sulfates in Valles Marineris (monohydrated Mg or Fe sulfate and polyhydrated s...
متن کاملLakes in Valles Marineris, Mars
Introduction: The question whether the Valles Marineris harbored lakes has been debated ever since McCauley [1] proclaimed that the horizontality and lateral continuity of the interior layered deposits (ILD) suggested that they were deposited in lakes. Recent evidence, summarized here, sheds new light on this old problem. Morphology and composition: The increasingly better resolution of images ...
متن کاملMorphology and geometry of Valles Marineris landslides
The walls of the Valles Marineris canyons are affected by about 45 landslides. The study of these landslides provides a test of the hypothesis of processes having affected Martian wallslopes after their formation. The dynamics of Valles Marineris landslides are controversial : either the landslides are interpreted as large debris flows or as dry rock avalanches. Their morphology and their topog...
متن کاملThe Formation of Valles Marineris, Mars
Introduction: Valles Marineris is the most prominent tectonic feature on Mars, consisting of troughs up to 2000 km in length, 200 km in width, and 10 km in depth. A scenario for trough formation is here proposed that is consistent with the geological and geophysical evidence, and predicts a priori the observed trough depths. The proposed mechanism entails a combination of Tharsis loading over t...
متن کاملGravity Observations of Structure in Valles Marineris, Mars
Introduction Valles Marineris is one of the most prominent tectonic structures on Mars. It is approximately 4000 km long [1] and up to 11 km deep [2]. Valles Marineris is oriented radial to the Tharsis volcanic province and formed primarily by normal faulting in an extensional rifting environment [3]. Detailed geologic mapping indicates that it formed primarily during the Early Hesperian [4], c...
