Layered mantling deposits in northeast Arabia Terra, Mars: Noachian-Hesperian sedimentation, erosion, and terrain inversion
[1] Thick, layered mantling deposits of different ages occur in several nonpolar regions of Mars and are thought to represent volcanic ash and/or climate-related ice-dust deposition. One such deposit is a layered mantling unit that unconformably blanketed highlands terrain in northeast Arabia Terra during the Late Noachian and/or earliest Hesperian. Shortly thereafter, by the mid-Hesperian, thi...
متن کاملLayered Mantle Deposits in Northeast Arabia Terra, Mars: I. Observations of Noachian-hesperian Sedimentation, Erosion and Terrain Inversion
Introduction and Background: Northeast Arabia Terra, west and north of Syrtis Major, has long been known to be characterized by significant terrain mantling and exhumation [1-3]. There are two widespread geological units at a scale of 1:15M [1]: dissected terrain (Npld; more highly dissected by valley networks (VN) than cratered unit; covers extensive area S and W of Syr-tis Major, interpreted ...

متن کاملDrainage basin evolution in Noachian Terra Cimmeria, Mars
[1] Geomorphic mapping of a 1 million square kilometer section of Terra Cimmeria on Mars (1:1M scale) indicates that prolonged, intense fluvial erosion occurred during the period of heavy bombardment. Crater counts date the termination of ubiquitous, intense erosion to the late Noachian, although some valleys may have continued downcutting into the early Hesperian. Stratigraphic and topographic...
متن کاملAncient Hydrothermal Springs in Arabia Terra , Mars
Introduction: Hydrothermal springs are important astrobiological sites for several reasons: 1) On Earth, molecular phylogeny suggests that many of the most primitive organisms are hyperthermophiles, implying that life on this planet may have arisen in hydrothermal settings [1-3]; 2) on Mars, similar settings would have supplied energyand nutrient-rich waters in which early martian life may have...
