(a) and (b) as a function of the two external tilt angles and for a single grain (marked in Fig. 9) of the anhydrite rock section with a thickness of 0.03 mm. The measurement was carried out at a wavelength of 600 nm for a total of 441 positions of the tilting stage. [The angular range of the orientation angle measured by the Metripol system is 0 ≤ ≤ 180°; this causes the 180° step seen in Fig. 10(b).] |
