Lamprophyres represent hydrous alkaline mantle melts that are a unique source of information about the composition of continental lithosphere. Here the authors use isotopic compositions of lamprophyres to map a hidden terrain boundary and an unknown fragment of Armorica in the mantle lithosphere of southwest Britain.
