Rum layered intrusion explained

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,[1] the remains of the eroded, solidified magma chamber of an extinct volcano[2] that was active during the Palaeogene Period.[3] It is associated with the nearby Skye intrusion and Skye, Mull and Eigg lavas.[4] It was emplaced 60 million years ago above the Iceland hotspot.[5] [6]
