The Hayabusa2 mission was tasked with returning samples from the C-complex asteroid Ryugu (1999 JU3), in order to shed light on the formation, evolution and composition of such asteroids. One of the main science objectives was to understand whether s

The genesis of hotspot magmatism remains controversial especially at continental margins such as offshore West Africa. Here, by analysing trace element and Pb isotopes of intraplate basalts, the authors conclude that their generation was caused by th
