Short summary
Methods of measuring trace water contents of quartz at high resolution using synchrotron infrared radiation and spectroscopy are described and applied to deformed rocks of the Moine Thrust of NW Scotland and the Main Central Thrust of the Himalaya in NW India. By imaging OH absorption bands, variations in water content can be linked to deformation microstructures, providing information on the histories of deformation, recovery, introduction and loss of water, and water weakening.
