Reflectance spectra of representative expanded vermiculite ore samples

Reflectance spectra of representative expanded vermiculite ore samples from each of the four major historical sources

Detailed Description

Reflectance spectra of representative expanded vermiculite ore samples from each of the four major historical sources: Libby, Montana; Louisa, Virginia; Enoree, South Carolina; Palabora, South Africa. The shapes of the 1.40- and 2.32-micrometer (μm) composite absorptions vary depending on sample mineralogy and composition. Arrows mark the long wavelength edge of the intense Fe-electronic absorption envelope; vertical lines mark the 2.24- and 2.38-μm composite absorptions
