Mineralogy Of Aeolian Deposits In Gale Crater, Mars: The Bagnold Dunes To Glen Torridon, Eleanor Moreland
Mineralogy Of Aeolian Deposits In Gale Crater, Mars: The Bagnold Dunes To Glen Torridon, Eleanor Moreland
Senior Honors Papers / Undergraduate Theses
We select four sand deposits along the traverse of the Curiosity rover to evaluate the spatial distribution of mineralogy and grain size. While extensive work has focused on characterizing the Bagnold Dunes in-situ and from orbit, less attention has been given to deposits south of the Vera Rubin Ridge (VRR). Overall, our results illustrate a compositional dichotomy among aeolian deposits, separated by the VRR. Initial investigations of hyperspectral data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) show differences in the long wavelength spectral features and absolute reflectance measurements for the deposit south of the Bagnold Dunes. The southern …

Arts & Sciences Electronic Theses and Dissertations
We are currently living in the golden age of robotic exploration of Mars, with a continued robotic presence there since 1997. Next to Earth, Mars is the planet about which we have gathered the most geologic information. Unlike Earth, Mars does not appear to have plate tectonics, and the planet’s primary and secondary crust is dominated by basalts. Understanding the compositional diversity of the materials that make up the martian crust will give us a better insight into the geologic processes that formed the planet and its subsequent evolution. One large and growing source of martian surface compositions is the …
Spectral And Stratigraphic Mapping Of Layered Sulfate Deposits On Mars Using Advanced Crism Data Processing Techniques, Kathryn Elizabeth Powell
Spectral And Stratigraphic Mapping Of Layered Sulfate Deposits On Mars Using Advanced Crism Data Processing Techniques, Kathryn Elizabeth Powell
Arts & Sciences Electronic Theses and Dissertations
We apply orbital remote sensing of Mars to analyze the mineralogy and geologic setting of two areas near rover landing sites. We use the Compact Reconnaissance Orbiter for Mars (CRISM) observations, modeled to single scattering albedo, to identify and map hydrated sulfates in layered sedimentary sequences in these two locations. In Meridiani Planum, the Opportunity rover has characterized a ~10 m section of sulfate-bearing deposits known as the Burns formation. At our study area in ~20 km to the south at Iazu Crater, we found that the crater walls have strong spectral signatures of polyhydrated sulfate, strongly correlated with a …
