• A review of water contents of nominally anhydrous natural minerals in the mantles of Earth, Mars and the Moon (2010, background): “slab-derived fluids or melts metasomatizing the mantle during the subduction of the Farallon plate (Dixon et al., 2004; Li et al., 2008).”
• The thermal structure of subduction zone back arcs (2004, background): “We further note that California and northern Mexico appear to be similarly hot [e.g., Goes and van der Lee, 2002; Dixon et al., 2004], although subduction terminated at 10–30 Ma.”
• Hydrogen incorporation in olivine from 2–12 GPa (2006, background): “…the past two decades as a result of new work on natural and synthetic NAMs as well as widespread recognition of the important inß uence of even trace amounts of OH on geochemical and geophysical processes (e.g., Hirth and Kohlstedt 1996; Asimow and Langmuir 2003; Karato 2003; Dixon et al. 2004).”
• Water, Melting, and the Deep Earth H 2 O Cycle (2006, background): “Subsequent studies have considered the relevance of this critical process to lateral variations in mantle viscosity (Dixon et al. 2004), the origin of the low velocity zone (Karato & Jung 1998), the pattern of flow and melting beneath ridge-centered hotspots (Ito et al. 1999), the major and trace…”
• Complex subduction and small-scale convection revealed by body-wave tomography of the western United States upper mantle (2010, background): “Hydration of the western U.S. lithosphere (Humphreys et al., 2003) and asthenosphere (Dixon et al., 2004; Yang and Forsyth, 2008) has been suggested, but lateral variations in hydration are unlikely to account for the 5–6% peak-to-peak VP/VS variations commonly imaged in the upper 200 km. Jacobsen…”
• Implications of deformation following the 2002 Denali, Alaska, earthquake for postseismic relaxation processes and lithospheric rheology (2006, result): “These slip estimates are generally consistent with those inferred from other geodetic [Wright et al., 2004], seismic [Ozacar and Beck, 2004], and combined GPS and seismic [Dreger et al., 2004; Oglesby et al., 2004] inversions in terms of the general location of high-slip patches.”
• Rheology of the Lower Crust and Upper Mantle: Evidence from Rock Mechanics, Geodesy, and Field Observations (2008, background): “Dixon et al. (2004) argued that addition of water from the subducting Farallon slab to the overlying mantle, as evidenced by geochemical studies of mantle xenoliths, further weakens mantle rheology below the tectonically active region.”
