Data of experimental investigation on the brittle-ductile transition of natural mafic granulite

The data set contains corrected stress-strain data of natural mafic granulite samples experimentally deformed in triaxial compression at temperatures of 950 – 1150°C and a confining pressure of 300 MPa, at varying strain rates between 10-4 s-1 and 10-6 s-1, and other relevant data of the figures in the paper. Depending on the applied conditions, which are nominally in the semi-brittle and ductile deformation regimes of mafic granulite, we observed the deformation characteristics of the brittle-ductile transition of natural mafic granulite. The experiments were performed on the cylindrical samples using a gas (argon) confining medium apparatus at State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing, China.
