- Summary:
- The Airborne Visible Infrared Imaging Spectrometer (AVIRIS) were used to map the distribution of ferric oxide, sulfate, and phyllosilicate minerals exposed on fresh and altered cones on the summit of Mauna Kea Volcano, Hawaii. Unaltered cones exhibit concentric zoning of iron oxide signatures with crystalline hematite located near the summits and nanophase iron oxide signatures found at the base of cones and on flow surfaces. Altered cones (Puu Poliahu and Puu Waiau) have exposures of three phyllosilicate and possible jarosite units. The relatively small spatial scale associated with alteration zones seen on Mauna Kea demonstrates the importance of obtaining high spatial resolution hyperspectral observations of Mars.
