What are the long-term geological consequences of hotspot volcanism?

Jan 4, 2019 ... Based on observations mainly made on the Hawaiian volcanoes the compositional evolution of hotspot volcanoes is believed to reflect the ... The hotspot is fixed, so as the plates move, the first volcano moves away from the source of magma, and then becomes extinct. A new volcano forms over the ... In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle ... Volcanic Hot Spots - A volcanic hot spot is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. Sep 1, 2009 ... Occasionally volcanoes can form right in the middle of a plate. These so-called “hotspot” volcanoes are created when a narrow stream of hot ... Auckland's volcanoes are powered by a 'hot spot' deep beneath the surface. The hot spot is a zone of magma fed by a plume of hot rock rising up out of the ... A 30 foot slice of volcano looks like most other rocky terrain. Unless it ... hotspot, volcanoes would form. They would build enormous shield-shaped ... Feb 11, 2020 ... A hotspot is a large plume of hot mantle material rising from deep within the Earth. A line of volcanoes develops as a plate moves over a hotspot. Jul 31, 2019 ... New data analyses from Rochester researchers show that the volcanic hot spots that helped form the Hawaiian islands are not fixed, but are in constant motion. A hotspot is a small area within the mantle which is of a higher temperature than the area surrounding it, and is usually associated with volcanic activity.
