Calibrations of phase abundance, composition, and particle size distribution for olivine-orthopyroxene mixtures from reflectance spectra

Cloutis, Edward A.; Gaffey, Michael J.; Jackowski, Timothy L.; Reed, Kevin L. (American Geophysical Union, 1986-10-10)

Spectral reflectance measurements of characterized (phase abundance, particle size) mixtures of olivine and orthopyroxene were utilized to define the correlations between spectral and albedo parameters of such assemblages ...

Pyroxene spectroscopy revisited: Spectral-compositional correlations and relationship to geothermometry.

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 ...

Reflectance spectra of "featureless" materials and the surface mineralogies of M- and E-class asteroids

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 ...

Metal-silicate mixtures: Spectral properties and applications to asteroid taxonomy.

Cloutis, Edward A.; Gaffey, Michael J.; Smith, Dorian G. W.; St. J. Lambert, Richard (Journal of Geophysical Research, 1990-06-10)

The reflectance spectra of combinations of olivine, orthopyroxene, and iron meteorite metal show systematic variations in spectral properties which can be used to constrain many of the physical and chemical properties of ...
