| 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 Panchruane
and Dalcap clays. |
