Mantle-sourced magmas erupted at hotspot volcanoes can provide clues to the sulphur cycle over geological timescales. In this work, sulphur isotopes were analysed in crystal-hosted inclusions entrapped at depth, and reveal the presence of post-Archaean recycled material in the Canary Island mantle.
