Geological Relationships between Hydrated Minerals and Fluvial Landforms in Tyrrhena Terra

Introduction: Tyrrhena Terra is located in cratered and dissected Noachian terrains in the southern hemisphere [1] south of Isidia Planitia and north of Hellas basin. Tyrrhena Terra contains both highlands and a series of intercrater plains. In this region, many outcrops of phyllosilicates are observed by OMEGA spectrometer on many craters walls or ejecta [2, 3]. Several plains in Tyrrhena Terr...

MRO’s HiRISE COVERAGE OF FLUVIAL LANDFORMS ON MARS DURING ITS PRIMARY

Introduction: The Mars Reconnaissance Orbiter's High-Resolution Imaging Science Experiment completed its primary science phase (lasting one Mars year) in November 2008. By the end of the primary science phase, the HiRISE camera completed 9549 observations for a total of approximately 8 Terabytes of data. These observations cover an area close to 938,000 km 2 or approximately 0.6% of the surface...

Fluvial fan deltas: Linking channel processes with large-scale morphodynamics

[1] Alluvial fan deltas are built by aggrading and avulsing river channels. A numerical model of flow and sediment transport in channels is combined with a condition for channel avulsion to describe evolution of the fan surface. The model combines elements of two recent approaches: (1) diffusional models of depositional basin filling, which describe the evolution of overall morphology, and (2) ...
