Usefulness of weak bands in midinfrared remote sensing of particulate planetary surfaces.

Transmittance and reflectance spectra of calcite and quartz are presented for the wavelength range from 4000 to 400 cm-1 (2.5-25 mu m). It is the purpose of this paper to point out that these weak bands are potentially useful for compositional remote sensing of particulate planetary surfaces; this will require completion of supporting laboratory studies to document the occurrence of weak bands. -from Authors
