Abstract

Clinohumite, a humite group mineral, originated from Pamir Mountains, USSR is used in the present work. Optical absorption, electron paramagnetic resonance (EPR), near infrared (NIR) and Mossabauer techniques are used in the characterization of the mineral sample. The optical absorption spectrum indicates that Fe(II) impurity is present in two sites with distorted octahedral structure. NIR results are attributed to water fundamentals. EPR studies on powder sample confirm the presence of Mn(II) in three different sites and also an iron impurity. Mossabauer studies confirm the presence of iron impurity in two different sites.
