Our experimental data provided here are consisting of: (1) Original files from the deformation experiments. All the data were recorded with frequency of 1 second (ti). Recorded parameters are stress (fi), confining pressure (pci) and displacement of sigma-1 (deformation) piston (dxi). (2) Original FTIR spectra from two experimental sets with H2O addition range 0 - 0.5 wt% (for H2O amount in samples, check Table 1 in the article). (3) Most important original EBSD files (.ctf).
