Fig. 9From: Strain localization and fabric development in polycrystalline anorthite + melt by water diffusion in an axial deformation experimentIR mapping results for the upper and lower sample boundaries of the water-added experiment. a Optical image (cross-polarized light with a gypsum plate). The compression direction (σ1) is shown by an arrow. The upper and lower sample boundaries are shown as white dashed lines. The IR-mapped area is shown as a gray rectangle. b IR mapping results shown as water contents in zoisite. c Raw IR spectra selected from (b). The numbers correspond to the parts in (b). The IR spectrum for the sample boundary corresponds to the No. 4 spectrum, and the calculated water content was 1500 ppm H2OBack to article page
