A large-strain, torsional deformation apparatus has been developed based on diamond anvil cells at high pressures, up to 135 GPa with a help of hard nano-polycrystalline anvils. These pressure conditions correspond the base Earth’s mantle. An X-ray laminography technique is introduced for high-pressure in situ 3D observations strain markers. The this study introduces possibility rheological measurements deep Earth materials under ultrahigh-pressure conditions.
