Emission spectrographic anaiysis of a light green apophyllite from Poona, India, indicates that 1600 ppm V and 350 ppm Mn are the principal trace constituents. Only 70 ppm Fe was found. Optical spectra have been obtained which indicate that tetravalent vanadium is primarily responsible for the color and dichroism of this material.
