    Small near-Earth asteroids (NEAs) (<20 m) are interesting, because they are progenitors for meteorites in our terrestrial collection. The physical characteristics of these small NEAs are crucial to our understanding of the ...
  • Cloutis, Edward A. (Journal of Geophysical Research, 2002-06-13)
    Reflectance spectra of a suite of compositionally diverse pyroxenes exhibit variable spectral properties which are associated with various elemental substitutions. Those associated with transition series elements, such as ...
  • Cloutis, Edward A.; Gaffey, Michael J. (Journal of Geophysical Research, 1991-12-25)
    Pyroxene reflectance and transmittance spectra have been examined in a search for systematic relationships between spectral features and compositional variations and to assess the applicability of reflectance spectroscopy ...
  • Cloutis, Edward A.; Gaffey, Michael J.; Smith, Dorian G.W.; St. J. Lambert, Richard (Journal of Geophysical Research, 1990-01-10)
    The 0.3- to 2.6-μm reflectance spectra of meteoritic enstatite (nearly pure MgSiO3), iron meteorite metal, magnetite and amorphous carbon, and various mixtures of these materials with mafic silicates have been measured in ...
  • Olsen, K. S.; Cloutis, E.; Strong, K. (Geophysical Research Letters, 2012-10-11)
    Intense interest in the characteristics of a methane source on Mars has been spurred by recent observations of a plume structure. The current NASA Mars Science Laboratory and future landers and orbiters will be tasked with ...
  • Cloutis, Edward A.; Asher, Pranoti M.; Asher, Pranoti M. (Journal of Geophysical Research, 2002-09-25)
    The 0.3- to 26-μm reflectance spectra of a suite of 28 zeolites were measured and analyzed to derive spectral-compositional-structural relationships. Below ~7 μm, the spectra are largely dominated by absorption features ...
  • Goltz, Douglas M.; Piniuta, Brent; Huebner, Erwin; Attas, Michael; Cloutis, Edward; Broomhead, John (International Journal of Conservation Science, 2013-01-01)
    In this study we describe the application of X-ray fluorescence, variable pressure scanning electron microscopy and visible (420-720 nm) hyperspectral imaging to assess the surface properties of a wood tally stick that ...
