High-resolution reflectance spectra of Mars in the 2.3-μm region: evidence for the mineral scapolite High-resolution reflectance spectra of Mars in the 2.3-μm region: evidence for the mineral scapolite
patially resolved reflectance spectra of Mars in the 2.2- to 2.4-μm spectral region were obtained in August 1988 using the NASA 3-m Infrared Telescope Facility. The spectra show weak absorption features due to Martian atmospheric carbon monoxide and a surface mineral. Both CO and the mineral absorptions are composed of overlapping narrow features, but in many locations, such as Hellas...

Mineral Resources of the Mount Nutt Wilderness Study Area, Mohave County, Arizona Mineral Resources of the Mount Nutt Wilderness Study Area, Mohave County, Arizona
The Mount Nutt Wilderness Study Area (AZ-020-024) is located in the Black Mountains about 15 mi west of Kingman, Arizona. At the request of the U.S. Bureau of Land Management, approximately 27,210 acres of the wilderness study area was evaluated for mineral resources (known) and mineral resource potential (undiscovered). In this report, the area studied is referred to as the 'wilderness...

Spectral characteristics of chlorites and Mg‐serpentines using high‐resolution reflectance spectroscopy Spectral characteristics of chlorites and Mg‐serpentines using high‐resolution reflectance spectroscopy
The present laboratory study using high‐resolution reflectance spectroscopy (0.25–2.7 μm) focuses on two primary phyllosilicate groups, serpentines and chlorites. The results show that it is possible to spectrally distinguish between isochemical end‐members of the Mg‐rich serpentine group (chrysotile, antigorite, and lizardite) and to recognize spectral variations in chlorites as a...

Search for volatiles on icy satellites: I. Europa Search for volatiles on icy satellites: I. Europa
New reflectance spectra have been obtained for both the leading and trailing sides of Europa, using the Cooled Grating Array Spectrometer (CGAS) of the NASA Infrared Telescope Facility (IRTF). The spectra are of higher precision than any yet obtained. Spectra of Europa's trailing side (central meridian longitude ≈300°) obtained in 1985 show two weak absorptions near 2.2 and 2.3 μm. Both...

Europa: Characterization and interpretation of global spectral surface units Europa: Characterization and interpretation of global spectral surface units
The Voyager global multispectral mosaic of the Galilean satellite Europa (T. V. Johnson, L. A. Soderblom, J. A. Mosher, G. E. Danielson, A. F. Cook, and P. Kupferman, 1983, J. Geophys. Res. 88, 5789–5805) was analyzed to map surface units with similar optical properties (T. B. McCord, M. L. Nelson, R. N. Clark, A. Meloy, W. Harrison, T. V. Johnson, D. L. Matson, J. A. Mosher, and L...

Spectral properties of ice‐particulate mixtures and implications for remote sensing: 1. Intimate mixtures Spectral properties of ice‐particulate mixtures and implications for remote sensing: 1. Intimate mixtures
The spectral properties of water ice-particulate mixtures are studied for the purpose of deriving the ice and particulate abundances from remotely obtained spectra (particulates referring to nonicy materials in the form of grains). Reflectance levels and ice absorption band depths are a complex function of the single scattering albedo of the particulates embedded in the ice. The ice...
