a Optical photomicrograph of the syenite sample showing undulose extinction in K-feldspar in cross-polarized light. b EBSD phase map of the syenite sample. c GROD map of K-feldspar in the syenite sample. Black lines indicate grain boundaries. Yellow lines indicate subgrain boundaries by misorientation ranged from 2° to 10°. The red box indicates the location of the area displayed in (d). d Enlarged GROD map of K-feldspar in the syenite sample showing intracrystalline deformation. The EBSD patterns were collected automatically using a step size 3 μm. Kfs: K-feldspar, Hbl: hornblende
