Jupiter’s moon Io is the most volcanically active body in the solar system, and is part of a growing class of discovered ‘lava-worlds’. These lava-worlds are typically assumed to have interiors dominated by convection. For Io, however, this is inconsistent with the observed surface heat flux. We present a model of coupled magmatism and volcanism showing that removal of tidal heat from Io’s mantle occurs predominantly by magmatic segregation. The mode and spatial variability of volcanoes on lava-worlds exerts a strong control on crustal thickness and interior melt fractions, whilst reducing the drive for mantle convection and precluding plate tectonics.
