Abstract

The analytical method is applied in locating pyroxene optical indicatrices, in thin sections, in the universal stage. Eight extinction operations were carried out for each section, with Φ= 45°, 135°, 225° and 315°. The main conclusion is that the analytical method may be used as a routine procedure in determining the optical properties of these minerals.
