Fluvial Depositional Landforms on Permeable Plain

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...

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...

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

Towards an Ontology of Landforms

The paper begins with the question “Do mountains exist?” It shows that providing an answer to this question is surprisingly difficult, and that the answer which one gives depends on the context in which the question is posed. Mountains clearly exist as real correlates of everyday human thought and action, and they form the archetype for geographic objects. Yet individual mountains lack many of ...
