Short summary
We reproduced in an experiment the mixing of two different magmas by bubbles. Bubbles form filaments when dragging portions of one magma into another and thus mingle both magmas. Bubble mixing must be an accelerating process in nature, because formed filaments are channels of low resistance for subsequently rising bubbles. In natural gas-rich magmas, this may be an important mechanism for magma mixing. Natural samples from Axial Seamount show evidence for bubble mixing.
