• Effect of GIA models with 3D composite mantle viscosity on GRACE mass balance estimates for Antarctica (2015, methodology): “Above 400 km, where olivine is the main mantle material, the olivine flow laws from Hirth and Kohlstedt (2003) are used to compute Bdiff and Bdisl: B = Ad−p f H2Oreαϕe− E+P VRT , (2) in which A and α are constants, d is the grain size, f H2O is water content, ϕ is melt fraction, E is activation…”
• The relationship between shear wave velocity, temperature, attenuation and viscosity in the shallow part of the mantle (2013, methodology): “What is even more surprising is that the activation energy for body diffusion of Si, measured by Fei et al. (2012) to be 410±30 kJ/mol, agrees with both that obtained here by fitting the geophysical and petrologic information and that of Hirth and Kohlstedt (2003).”
• A 3‐D numerical study of the thermal evolution of the Moon after cumulate mantle overturn: The importance of rheology and core solidification (2013, methodology): “This viscosity is the experimentally determinated upper bound at 1300°C for a dry mantle composition comparable to the Earth’s upper mantle [Hirth and Kohlstedt, 2003].”
• Polycrystal anelasticity at near‐solidus temperatures (2016, result): “The obtained dependence on 𝜙 is consistent with that of YAMAUCHI AND TAKEI ANELASTICITY AT NEAR-SOLIDUS TEMPERATURE 7800 partially molten rocks, which is usually represented as 𝜂 ∝ e−𝜆𝜙 with 𝜆 = 25–30 [Mei et al., 2002; Hirth and Kohlstedt, 2003].”
• A thermodynamically self-consistent damage equation for grain size evolution during dynamic recrystallization (2011, methodology): “Typically n ∼ 3 and m ∼ 3 (Hirth & Kohlstedt 2003; Kohlstedt 2007).”
• Mechanisms for the generation of plate tectonics by two-phase grain-damage and pinning (2012, background): “…positive feedback occurs because of the interaction of grain-size dependent rheologies (such as diffusion creep or grain-boundary sliding; see Hirth and Kohlstedt (2003)) and grain-reduction driven by deformation through dynamic recrystallization (e.g., Karato et al., 1980; Urai et al.,…”
