The Rum layered intrusion is located in Scotland, on the island of Rùm (Inner Hebrides). It is a mass of intrusive rock, of mafic-ultramafic composition, the remains of the eroded, solidified magma chamber of an extinct volcano^[1] that was active during the Palaeogene Period.^[2] It is associated with the nearby Skye intrusion and Skye, Mull and Egg lavas.^[3] It was emplaced 60 million years ago above the Iceland hotspot.^[4]^[5]
