In Situ Falling Sphere Measurements of the Viscosity of Silicate Melts at High Pressures

Abstract

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… (More)
