Mechanical data for: High temperature friction and strength of felsite and basalt: Implications for supercritical EGS at Krafla, Iceland

All mechanical data of the examined felsite and basalt rocks are provided in ASCII dat files, and each data set is given a separate folder. Sample number, temperature and confining pressure (for saw-cut samples) is indicated by the folder names. In every file, the first column is strain (in %) and the second column is stress (in MPa) of deformed solid and saw-cut samples of felsite and basalt. For deformation of the solid rocks, we used a confining pressure of 50 MPa. Every sample was deformed at a constant axial displacement velocity of around 60 µm/min. The initial sample dimensions are 10 x 20 mm.
