(a) Optical microscope photograph of Tsukuba gabbroic rock. (b) and (c) show polarization microscope images under reflective conditions of the black area A and the white area B, respectively. The angles of the polarizer are shown. These observed areas are selected from the sample area shown as solid frames in (a), which correspond to analyzed areas for XAFS imaging. The dashed frames (2.7 mm × 3.4 mm) indicate the viewing area for observation using the polarization microscope. |
