Imaging spectroscopy of geological samples and outcrops: Novel insights from microns to meters
(GSA Today, 2015-12-01)
Imaging spectroscopy is a powerful, non-destructive mineralogic tool that provides insights into a variety of geological processes. This remote measurement technique has been used for decades from orbital or aerial platforms ...
Detection of rotational spectral variation on the M-type asteroid (16) Psyche
(The Astronomical Journal, 2016-12-28)
The asteroid (16) Psyche is of scientific interest because it contains ∼1% of the total mass of the asteroid belt and is thought to be the remnant metallic core of a protoplanet. Radar observations have indicated the ...
Spectral reflectance properties of zeolites and remote sensing implications
(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 ...
Submicroscopic metallic iron in lunar soils estimated from the in situ spectra of the Chang’E-3 mission
(Geophysical Research Letters, 2017-04-22)
Submicroscopic metallic iron (SMFe) created by space weathering has strong effects on the optical properties of the lunar surface. Spectra measured in situ by the visible-near-infrared spectrometer (VNIS) on board the ...
Reflectance spectra of "featureless" materials and the surface mineralogies of M- and E-class asteroids
(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 ...
