‘Hot Spots Volcanics’
Throughout Geological Time
Hot Spots Not Associated With
Plate Tectonics
Hot spots and mantle plumes:
• Caused by rising plumes of deep mantle
material
• Volcanoes can form over them (Hawaiian
Island chain)
• Mantle plumes
– Long-lived structures
– Some originate at great depth, perhaps
at the mantle-core boundary
