Geomorphic study of fluvial landforms on the northern Valles Marineris plateau, Mars

Mars Reconnaissance Orbiter observations of light-toned layered deposits and associated fluvial landforms on the plateaus adjacent to Valles Marineris

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 ...

The 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...

Fluvial and lacustrine activity on layered deposits in Melas Chasma, Valles Marineris, Mars

[i] Valley networks on Mars are the most obvious features attesting that different geologic processes and possibly climatic conditions existed in the past. THEMIS images reveal valley networks within Melas Chasma, in Valles Marineris, a Hesperian-age canyon system. The valley networks in Melas Chasma are dense and highly organized, and the heads of the valleys are scattered at different elevati...
