‘‘Hot Spots Volcanics’ Hot Spots Volcanics’ Throughout Geological TimeThroughout Geological Time
Hot Spots Not Associated Hot Spots Not Associated With Plate TectonicsWith 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
