Dislocation creep of olivine: Backstress evolution controls transient creep at high temperatures

LN Hansen, D Wallis, T Breithaupt… - Journal of …, 2021 - Wiley Online Library
Transient creep occurs during geodynamic processes that impose stress changes on rocks
at high temperatures. The transient is manifested as evolution in the viscosity of the rocks …
