Bright and dark regions on Mars: Particle size and mineralogical characteristics based on thermal emission spectrometer data
- S. Ruff, P. Christensen
- Materials Science, Geology
- 1 December 2002
[1] Emissivity spectra (1670–200 cm−1) from the Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) show significant differences between bright and dark surfaces, allowing further… Expand
A thermal emission spectral library of rock-forming minerals
- P. Christensen, J. Bandfield, +5 authors W. Stefanov
- Materials Science
- 25 April 2000
A library of thermal infrared spectra of silicate, carbonate, sulfate, phosphate, halide, and oxide minerals has been prepared for comparison to spectra obtained from planetary and Earth-orbiting… Expand
Mars Global Surveyor Thermal Emission Spectrometer experiment: Investigation description and surface science results
- P. Christensen, J. Bandfield, +23 authors M. Greenfield
- Geology
- 25 October 2001
The Thermal Emission Spectrometer (TES) investigation on Mars Global Surveyor (MGS) is aimed at determining (1) the composition of surface minerals, rocks, and ices; (2) the temperature and dynamics… Expand
Detection of Silica-Rich Deposits on Mars
- S. Squyres, R. Arvidson, +15 authors P. A. D. de Souza
- Geology, Medicine
- Science
- 23 May 2008
Mineral deposits on the martian surface can elucidate ancient environmental conditions on the planet. Opaline silica deposits (as much as 91 weight percent SiO2) have been found in association with… Expand
Quantitative thermal emission spectroscopy of minerals: A laboratory technique for measurement and calibration
- S. Ruff, P. Christensen, P. Barbera, D. L. Anderson
- Materials Science
- 10 July 1997
Previous descriptions of thermal emission spectroscopy have presented techniques that vary in accuracy and reproducibility. Contributions of thermal energy from the instrument and environment are… Expand
Detection of crystalline hematite mineralization on Mars by the Thermal Emission Spectrometer: Evide
- P. Christensen, J. Bandfield, +13 authors M. Smith
- Geology
- 25 April 2000
The Thermal Emission Spectrometer (TES) instrument on the Mars Global Surveyor (MGS) mission has discovered a remarkable accumulation of crystalline hematite (a-Fe2O3) that covers an area with very… Expand
Alkaline volcanic rocks from the Columbia Hills, Gusev crater, Mars
- H. Mcsween, S. Ruff, +11 authors M. Schmidt
- Geology
- 1 September 2006
[1] Irvine, Backstay, and Wishstone are the type specimens for three classes of fine-grained or fragmental, relatively unaltered rocks with distinctive thermal emission spectra, found as float on the… Expand
Provenance and diagenesis of the evaporite-bearing Burns formation, Meridiani Planum, Mars
- S. McLennan, J. Bell, +29 authors A. Yen
- Geology
- 30 November 2005
Abstract Impure reworked evaporitic sandstones, preserved on Meridiani Planum, Mars, are mixtures of roughly equal amounts of altered siliciclastic debris, of basaltic provenance (40 ± 10% by mass),… Expand
Characteristics, distribution, origin, and significance of opaline silica observed by the Spirit rov
- S. Ruff, J. Farmer, +8 authors S. Squyres
- Geology
- 1 July 2011
[1] The presence of outcrops and soil (regolith) rich in opaline silica (∼65–92 wt % SiO2) in association with volcanic materials adjacent to the “Home Plate” feature in Gusev crater is evidence for… Expand
