A Preliminary Study on Identification of Clay Minerals in Soils with Reference to Reflectance Spectra

摘要

The characteristics of the reflectance spectra of clay minerals and their influences on the reflectance spectra of soils are dealt with in the paper. The results showed that dominant clay minerals in soils could be distinguished in light of the spectral-form parameters of the reflectance spectra of soils, thus making it possible to develop a quick method to determine clay minerals by means of reflectance spectra of soils in the lab, and providing a theoretic basis for remote sensing of clay mineralsin soils with a high resolution imaging spectrometer.
