IR mapping result for oligoclase–biotite zone specimen No. 7-26, which represents the highest grade of metamorphism in the study area. a Optical photomicrograph, plane-polarized light. b Cross-polarized light. The IR mapped areas are shown by squares. c Water distributions using the calibration of Paterson (1982). Numbers represent raw IR spectra in d
