Toward a general viscosity equation for natural anhydrous and hydrous silicate melts (2007, background): “…various silicate melts, from felsic (e.g., rhyolitic melt, Neuville et al., 1993) to ultramafic composition (e.g., peridotite liquid, Dingwell et al., 2004), from anhydrous (e.g., Neuville et al., 1993) to hydrous ones (e.g., Whittington et al., 2000), and from high temperature to low temperature.”
Electrical conductivity of hydrous basaltic melts: implications for partial melting in the upper mantle (2011, background): “This trend differs from that observed for viscosity, i.e., the effect of dissolved water is larger for polymerized melts than for depolymerized melts (e.g., Whittington et al. 2000 ), because water preferentially reacts with bridging oxygen atoms.”
Dissolution mechanisms of water in depolymerized silicate melts: Constraints from 1H and 29Si NMR spectroscopy and ab initio calculations (2004, background): “There are only limited studies concerning the effect of water on the viscosities of more depolymerized silicate melts (Scarfe, 1973; Persikov et al., 1990; Persikov, 1991; Whittington et al., 2000; Whittington et al., 2001).”
