Resumen

Optical microscopy is a basic but still indispensable tool for examining mineral parageneses in ores. The design and concepts behind the reflected light ore microscope have obviously not been subject to spectacular technical evolutions in the last decades. However, digital imaging capabilities have opened new and stimulating perspectives for automated mineral identification. Recent works in developing multispectral image analysis (Pirard, 2004) have demonstrated its superior potential with respect to conventional colour imaging, but at the same time reconciliation with spectroscopic databases such as the Quantitative Data File III (Criddle and Stanley, 1993) still needs a more in-depth investigation as well as the possibility to extend both imaging and spectroscopy into the near infrared domain. In this paper, the authors present results gained from multispectral imaging in the range between 400 and 1000 nm together with spectrophotometric data from the QDFIII database, with an emphasis on minerals that cannot be easily distinguished in the visible spectrum.
