COMPOSITIONAL CLASSIFICATION OF "KIMBERLITIC" AND "NON-KIMBERLITIC" ILMENITE

Wyatt B.A.; Baumgartner M.; Anckar E.; Grutter H. (2004)

Ilmenite is one of the common kimberlitic indicator minerals recovered during diamond exploration, and its distinction from non-kimberlitic rock types is important. This is particularly true for regions where these minerals ...
THE STRUCTURE OF HEMATITE (α-FE2O3) (001) SURFACES IN AQUEOUS MEDIA: SCANNING TUNNELING MICROSCOPY AND RESONANT TUNNELING CALCULATIONS OF COEXISTING O AND FE TERMINATIONS

Eggleston C.M.; Stack A.G.; Higgins S.R.; Bice A.M.; Boese S.W.; Pribyl R.D.; Nichols J.J.; Rosso K.M. (2003)

The iron oxide–water interface is of interest not only in geochemical and environmental processes, but also in fields ranging from corrosion to photocatalysis. The structure of α-Fe2O3 (001) surfaces is not fully understood, ...
THE VISIBLE DIFFUSE REFLECTANCE SPECTRUM IN RELATION TO THE COLOR AND CRYSTAL PROPERTIES OF HEMATITE

Torrent J.; Barrón V. (2003)

Hematite (α-Fe2O3) possesses distinct spectral properties which facilitate its identification in mineral mixtures. This paper reports the relationships between the visible diffuse reflectance (DR) spectrum and the color ...
