Fig. 5From: Water distribution in quartz schists of the Sanbagawa Metamorphic Belt, Japan: infrared spectroscopic mapping and comparison of the calibrations proposed for determining water contentsIR mapping result for chlorite-zone specimen No. 7-93. 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. Spectra for the lowest (line 1) and highest (line 2) water contents are shown. Other spectra are mixtures of quartz (Qtz) and phyllosilicates (Phyl) and show large variations in band components and water contentsBack to article page
