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.本次受试的霏细岩（felsite）与玄武岩（basalt）的全部力学数据均以美国信息交换标准代码（ASCII）格式的dat文件提供，且每个数据集均配有独立文件夹。文件夹名称标注了样品编号、试验温度以及针对锯切样品的围压。每个文件的第一列为应变（单位：%），第二列为霏细岩与玄武岩的完整岩块及锯切样品受载变形后的应力（单位：MPa）。针对完整岩块的变形试验，我们采用了50 MPa的围压条件。所有样品均以约60 µm/min的恒定轴向位移速率完成变形测试。样品的初始尺寸为10 × 20 mm。
