Three-dimensional crystal scale fine model. (a) The 3D numerical rock specimen used with the grains assigned as potassium feldspar (blue), quartz (pink), plagioclase (green), biotite (peach) (as guided by the modal composition of the studied granite, the allocation of minerals is performed in a random manner). The outline of the polyhedral (the grains) can be seen. (b) 2D slice of a cube numerical specimen showing the different grain-to-grain contacts (color figure online).
