Near-infrared Spectral Diversity of the Ferrar Dolerite in Beacon Valley, Antarctica: Implications for Martian Climate & Surface Compositions

Petrology and Mineral Chemistry of the Antarctic Ferrar Dolerite: Implications for Martian Meteorites

Introduction: The study of terrestrial analogs to Martian igneous rock compositions and surface features is important in order to gain insight into past and present dynamic processes experienced on Mars. Previous Martian analog studies have been performed on materials from various terrestrial environments [e.g., 1-3]. For this study, we investigated petrological and mineralogical properties of ...

Characterization of spectral and geochemical variability within the Ferrar Dolerite of the McMurdo Dry Valleys, Antarctica: weathering, alteration, and magmatic processes

Orbital spectroscopy and laboratory analyses are utilized to identify major geochemical variations throughout the Ferrar Dolerite exposed in the McMurdo Dry Valleys (MDV) of Antarctica. Our laboratory results highlight the range of primary and secondary chemical and spectral variations observed throughout the dolerite, and provide the necessary calibration for detailed orbital investigations. P...

Plio-Pleistocene history of Ferrar Glacier, Antarctica: Implications for climate and ice sheet stability

The areal distribution and elevation of glacial drifts in Vernier Valley, southern Victoria Land, are used to reconstruct the PlioPleistocene history of upper Ferrar Glacier. Ne cosmogenic-nuclide analyses of surface cobbles on four moraines, Ferrar 1, 2, 3, and 4, provide age control. A minimum-age estimate for Ferrar Drifts calculated by assuming zero surface erosion indicates that the oldest...
