Salt tectonics and collapse of Hebes Chasma, Valles Marineris, Mars
A photogeologic and physical modeling study indicates that Hebes Chasma, Mars, formed by collapse of the megaregolith. Local heating facilitated drainage of ~105 km3 of brines and entrained particulates through fractures in the chasma fl oor and into a regional aquifer. A megaregolith rich in salts and water is implied by massive, low-gradient allochthonous fl ows that terminate in deep pits an...
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 کاملSulfate and hematite stratigraphy in Capri Chasma, Valles Marineris
Introduction: Analysis of OMEGA and CRISM spectral data for sulfate-rich Interior Layered Deposits (ILDs) in Valles Marineris has revealed complex assemblages of iron oxides and multiple sulfates [1-7]. We have been developing stratigraphic assemblages to assess the similarities and differences among chasma [3, 5, 7]. Here we present sulfate and iron oxide stratigraphy within the central ILD of...
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 کاملFluvial 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...
