FIG. 9. Calibrated digital video images taken with interference filters at wavelengths of 438 nm, 591 nm and 692 nm (from left to right). The upper sequence pictures a copper sulphide paragenesis in Kipushi, the central sequence is taken on a stannite-bearing ore from Vernerov and the lower sequence is from the sulphide paragenesis of the Panasqueira tin-tungsten deposit. Variable reflectance intensities are clearly noticeable for minerals such as bornite (Bo), pyrite (Py), arsenopyrite (Apy), chalcopyrite (Cp) and stannite (Sta).
