Weakening Effect of Graphite on the High-Temperature Dislocation Creep of Olivine–Graphite Aggregates

This data set is about the raw data on deformation of olivine-graphite aggregates at confining pressures of ~300 MPa and temperatures of 1423- 1523K in a Paterson gas-medium apparatus. This data set can be used to inverstigate the dislocation creep of olivine-graphite aggregates and weakening effects of graphite. Results show that increasing graphite content leads to progressive weakening of olivine–graphite aggregates, accompanied by systematic variations in rheological parameters.
