Size effects resolve discrepancies in 40 years of work on low-temperature plasticity in olivine

Abstract:

The strength of olivine at low temperatures and high stresses in Earth’s lithospheric mantle exerts a critical control on many geodynamic processes, including lithospheric flexure and the formation of plate boundaries. Unfortunately, laboratory-derived values of the strength of olivine at lithospheric conditions are highly variable and greatly disagree with those inferred from geophysical observations. Here we demonstrate via nanoindentation that the strength of olivine depends on the length-...
