Study by Raman microscopy of a rock section
coming from the village of Viu in the Alps of northern Italy. Three
types of samples have been examined: a thick section (100 to 200 µ
thickness), a normal thin section and a polished slab. Images of the 3
preparations will be used to identify the locations of the Raman spectra
at 532 and 633 nm. About 13 different minerals have been
discovered in this rock with the Raman microscope.
