Layers of mafic and ultramafic intrusive rocks forming the mountain of Hallival

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]
