Lakes 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 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...
متن کاملThin‐skinned deformation of sedimentary rocks in Valles Marineris, Mars
[1] Deformation of sedimentary rocks is widespread within Valles Marineris, characterized by both plastic and brittle deformation identified in Candor, Melas, and Ius Chasmata. We identified four deformation styles using HiRISE and CTX images: kilometer‐scale convolute folds, detached slabs, folded strata, and pull‐apart structures. Convolute folds are detached rounded slabs of material with al...
متن کاملStability of rock slopes in Valles Marineris, Mars
[1] New slope measurements from the Mars Orbiter Laser Altimeter (MOLA), in conjunction with the Rock Mass Rating system (RMR), permit inversions of slope height and angle from wallrock and interior deposits within Valles Marineris troughs for strength and lithology. Wallrock (50 < RMR < 65) is stronger than interior deposits (30 < RMR < 55). These values are consistent with layered igneous roc...
