• Water distribution across the mantle transition zone and its implications for global material circulation (2011, unknown): “Its abundance is small compared to other components (SiO2, MgO, CaO, etc.), yet even a small amount of water can modify the melting relationships (e.g., Inoue, 1994) and rheological properties (e.g., Karato and Jung, 2003; Mei and Kohlstedt, 2000) drastically.”
• A new analysis of experimental data on olivine rheology (2008, background): “…in the past to derive its dependence on temperature, pressure, stress, grain size, and composition [e.g., Weertman, 1970; Goetze and Evans, 1979; Chopra and Paterson, 1984; Karato et al., 1986; Bai et al., 1991; Hirth and Kohlstedt, 1995a; Mei and Kohlstedt, 2000a; Karato and Jung, 2003].”
• Generation of intermediate-depth earthquakes by self-localizing thermal runaway (2009, background): “Deformation and metamorphism are always associated with infiltration of external fluids and the fluids caused the infiltrated parts of the gabbro to become more reactive and thereby weaker relative to their dry precursor”
• Effect of water and stress on the lattice-preferred orientation of olivine (2006, methodology): “, 1996; Wallace, 1998; Jung and Karato, 2001a,b) and water is known to have significant effect on the plastic deformation of olivine (Carter and Avé Lallemant, 1970; Chopra and Paterson, 1981, 1984; Mackwell et al., 1985; Karato et al., 1986; Mei and Kohlstedt, 2000a,b; Jung, 2002; Karato and Jung, ”
