In this paper, the problems of the distinguishing characters and the cal- culative method of Polarization Color Indices of ore minerals are discussed. The new. calculative method of Polarization Color Indices of ore .minerals according to the Standard System (XYZ) of C. I. E is established. The counting method and processes are described. The luminance, hue and degree of saturation or purity of excitement of Polarization Color of ore minetals can be obtained from above new calculative method with SE as light source. The Polarization Color Indices of more than hnadred ore minerals are given. The systematic data, which include the Lumi- name of Polarization Color Rvis ( % ). Chromaticity Coordinates x, y, Dominant wave length dd (run), and Degree of saturation Fe of Polarization Color Indices, will aid to identify the main anisotropic ore minerals.
