Erosion, burial, and exhumation at Ganges Mensa, Mars

چکیده
Ross A. Beyer, NASA Ames Research Center, MS 245-3, Moffett Field, CA, USA ([email protected]) Ganges Mensa is a large mesa-like structure located near 311 E, 7.5 S on Mars within the Ganges Chasma. The slopes and surfaces of Ganges Mensa display a variety of morphologies, indicating that units of variable lithology constitute the stratigraphic stack of the mensa as observed by many previous studies. Excellent coverage by the Mars Orbiter Camera (MOC) [1, 2], the Mars Orbital Laser Altimeter (MOLA) [3, 4], and the Thermal Emission Imaging System (THEMIS) [5] shows that almost all surfaces on Ganges Mensa are heavily eroded and that there is evidence for burial and later exhumation of surfaces.

He–Pb double dating of detrital zircons from the Ganges and Indus Rivers: Implication for quantifying sediment recycling and provenance studies
He–Pb double dating of detrital zircons is more reliable than conventional U–Pb dating for tracing the source of detritus in sediments and can be used to constrain the percentage of recycled material in sediments. Conventional U–Pb dating can be used to constrain the provenance of sediments if the U–Pb zircon age pattern for potential source regions is known but can only be used to trace the so...
متن کاملExhumation of high-pressure rocks driven by slab rollback
Rocks metamorphosed under high-pressure (HP) and ultra high-pressure (UHP) conditions in subduction zones come back to the surface relatively soon after their burial and at rates comparable to plate boundary velocities. In the Mediterranean realm, their occurrence in several belts related to a single subduction event shows that the burial-exhumation cycle is a recurrent transient process. Using...
متن کاملMars sedimentary rock erosion rates constrained using crater counts, with applications to organic-matter preservation and to the global dust cycle
Small-crater counts on Mars light-toned sedimentary rock are often inconsistent with any isochron; these data are usually plotted then ignored. We show (using an 18-HiRISE-image, > 10 4 -crater dataset) that these non-isochron crater counts are often well-fit by a model where crater production is balanced by crater obliteration via steady exhumation. For these regions, we fit erosion rates. We ...

متن کاملWind-Driven Erosion and Exposure Potential at Mars 2020 Rover Candidate-Landing Sites
Aeolian processes have likely been the predominant geomorphic agent for most of Mars' history and have the potential to produce relatively young exposure ages for geologic units. Thus, identifying local evidence for aeolian erosion is highly relevant to the selection of landing sites for future missions, such as the Mars 2020 Rover mission that aims to explore astrobiologically relevant ancient...
