regions with high hematite index values were extracted and examined in detail. Factor analysis and target transfor-mation techniques [Malinowski,1991;Bandfield et al., 2000, 2002] were applied to the TES spectra to confirm the presence of crystalline hematite. Finally, linear decon-volution [Ramsey and Christensen, 1998] was used to

Jul 25, 2012· [8] TES emissivity spectra have been analyzed for hematite mineral detection. Each of the six TES detectors has an instantaneous field of view of ∼8.5 mrad, which equates to a spatial resolution of ∼3 × 8 km. TES is a Fourier‐Transform Michelson interferometer that covers the wavelength range from 6 to 50 μ m, or ∼1670 to 200 cm −1 [Christensen et al., 1992].

University of Minnesota's Mineral Pages: Hematite

With few exceptions, the economic uses of hematite revolve about its iron-rich composition and characteristic red color. Its name comes from 'haima', the Greek words for blood, a reference to hematite's distinctive color. Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that ...

Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

hematite | Definition, Uses, & Facts | Britannica

Hematite, heavy and relatively hard oxide mineral, ferric oxide, that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for 'blood,' in allusion to its red color. Learn more about hematite in this article.

Hematite's Streak: All specimens of hematite will produce a reddish streak. The streak of a mineral is its color in powdered form when scraped across a streak plate (a small piece of unglazed porcelain used to produce a small amount of mineral powder). Some specimens of hematite will produce a brilliant red streak, others will produce a reddish brown streak.

second method determines a hematite "index" on un-corrected emissivity spectra. The index is the sum of the two band depths at 550cm-1 and 450 cm-1 relative to the peak height at 500cm-1 (A-B)+(A-C), where A is the emissivity at the peak and B and C are values at the band centers. The two methods correlate extremely
