Abstract

<p>Viscosity is one of the important transport properties controlling the migration of magma in the Earth's interior. Experimental and geochemical studies have shown that magma is generated in the deep interior in the presence of CO<sub>2</sub>. However, our knowledge of the effect of CO<sub>2</sub> on the viscosity of magma (silicate melt) is limited. In this work, the viscosity of a molten jadeite composition containing 0.5 wt% CO<sub>2</sub> was measured under high pressure. We observed that in the presence of CO<sub>2</sub>, the viscosity was one to two orders of magnitude lower than without CO<sub>2</sub>.</p>
