Development of a new laboratory technique for high-temperature thermal emission spectroscopy of silicate melts
[1] With the prevalence of glass and molten silicates in volcanic environments, and the important role of surface emissivity in thermal infrared (TIR) measurements, it is imperative to characterize accurately the spectral features associated with silicate glasses and melts. A microfurnace has been developed specifically for use with a laboratory Fourier transform infrared (FTIR) spectrometer to...
متن کاملViscosity models for silicate melts
Rheology of silicates (melts or super cooled as glasses) is one of the most important fields to mankind, as geological activity largely influences life. In this paper, unifying empirical models for the Non-Newtonian shear viscosity and the extensional viscosity are proposed. The models have only one parameter, the zero shear viscosity (the Newtonian plateau), and are valid for a vide range of c...
متن کاملStructure and dynamics of magnesium in silicate melts: A high-temperature 25Mg NMR study
25Mg NMR spectra for several silicate and aluminosilicate melts were obtained from 1000–1470 8C. The peaks are initially very broad, but narrow with increasing temperature to near 500 Hz at the highest temperatures. The peak positions for most of the melts do not shift noticeably with temperature in the range studied, except for a sodium magnesium silicate composition that was previously studie...
متن کاملGeological Notes Diffusion of Water in Silicate Melts
The transport of water in silicate melts is examined from a theoretical point of view, taking into account the presence of both H20 and OH species. It was assumed that only H20 molecules may diffuse and that a constitutive relationship between the number density nH 0 of H20 molecules and the total water content (n:E) exists such that nH,o = g(n:E) . This is related to dissociation or to chemica...
متن کاملIn Situ Falling Sphere Measurements of the Viscosity of Silicate Melts at High Pressures
Introduction Experimental measurements of viscosity are critical to understanding igneous processes in the Earth’s mantle that control the rate of extraction of melts from partially molten source regions and the time scales for magma mixing. Traditionally, the settling velocity of a highdensity sphere through a molten sample is determined from the initial and final positions of the sphere and e...
