title: Electron paramagnetic resonance, NIR studies on zoisite, clinozoisite and chrom-zoisite minerals.
abstract: A zoisite group of mineral samples from different localities are used in the present study. An EPR study on powdered samples confirms the presence of Mn(II), Fe(III) and Cr(III) in the minerals. NIR studies confirm the presence of these ions in the minerals.
