Abstract
IR absorption spectra of four clay samples of Nepal are studied by KBr pellet technique. It was observed that Daman, Panchmane and Dalcap clay spectra show the two distinct peaks of a kaolinite in the OH absorption region. Daman clay spectrogram also shows some peaks between 910 and 1125 cm–1 which are assigned to a kaolinite mineral. On the basis of this study, it is, therefore, suggested that Daman clay is more kaolinitic than the Panchmane and Dalcap clays.
