摘要：

Reflection spectra of particulate samples of minerals that commonly occur in hydrothermally altered rocks and soils were recorded to display their features at their natural spectral bandwidths in the near-infrared from 1.3 to 2.4 micrometre. Atmospheric transmission spectra were recorded over limited wavelength segments in the same region to demonstrate the availability of some of the diagnostic mineral bands that occur close to regions of intense absorption. For remote-sensing purposes, the features in the 2.2 micrometre region are emphasized as particularly valuable because they are common to alteration minerals and allow discrimination from nonalteration minerals which provide features only as close as 2.4 micrometre. Detection of unique features near 1.76 micrometre that occur only in alunite and gypsum is possible through the atmosphere and so provides diagnostic potential. -from Author
