The timescale of structural relaxation in a silicate melt defines the transition from liquid (relaxed) to glassy (unrelaxed) behavior. Structural relaxation in silicate melts can be described by a relaxation time, z, consistent with the observation that the timescales of both volume and shear relaxa

The frequency-dependence of the shear viscosity and modulus of rhyolite melt has been determined over a 10-14 loglo Pa s viscosity range and a 0.03-63 rad s-1 angular frequency range. The frequency-dependent viscosity determined at high frequencies is 5 orders of magnitude lower than the Newtonian v
