This data set is about the raw data on deformation of 10 water-unsaturated, 2 anhydrous and 2 water-saturated diopside aggregates at confining pressures of ~300 MPa and temperatures of 1323- 1523K in a Paterson gas-medium apparatus. This data set can be used to inverstigate the dislocation creep of polycrystalline diopside aggregates and water-weakening effects. Results show that the strength of diopside was comparable in strength to that of olivine under dry conditions but weaker than that of olivine under water-saturated conditions in the dislocation creep regime, showing remarkable water-weakening effect.
