Bright and dark regions on Mars: Particle size and mineralogical characteristics based on thermal emission spectrometer data
[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 furtherExpand
A thermal emission spectral library of rock-forming minerals
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-orbitingExpand
Mars Global Surveyor Thermal Emission Spectrometer experiment: Investigation description and surface science results
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 dynamicsExpand
Detection of Silica-Rich Deposits on Mars
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 withExpand
Quantitative thermal emission spectroscopy of minerals: A laboratory technique for measurement and calibration
Previous descriptions of thermal emission spectroscopy have presented techniques that vary in accuracy and reproducibility. Contributions of thermal energy from the instrument and environment areExpand
Detection of crystalline hematite mineralization on Mars by the Thermal Emission Spectrometer: Evide
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 veryExpand
Alkaline volcanic rocks from the Columbia Hills, Gusev crater, Mars
[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 theExpand
Provenance and diagenesis of the evaporite-bearing Burns formation, Meridiani Planum, Mars
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
[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 forExpand
Characterization and petrologic interpretation of olivine‐rich basalts at Gusev Crater, Mars
Additional co-authors: PR Christensen, BC Clark, JA Crisp, DJ DesMarais, T Economou, JD Farmer, W Farrand, A Ghosh, M Golombek, S Gorevan, R Greeley, VE Hamilton, JR Johnson, BL Joliff, GExpand
