Figure 9
Simulated (A, B) and measured (C) log-normalized diffraction patterns from four 20 µm-thick – grain slices of α-quartz (SiO2). The diffraction pattern was integrated over a 10° sample rotation interval and is displayed with increasing levels of magnification in columns A, B and C, with the full tiled detector depicted in A1, B1 and C1. Diffraction peaks present in the true measured data which are only captured after the introduction of a random mosaicity are marked with circles. Diffraction peaks present in the simulated data but missing in the measurements are marked with squares. |
