What is the role of water in the generation and eruption of hotspot magmas?

The Hawaiian Islands are the youngest volcanic mountains in a long chain of volcanoes that formed over a hotspot. They are still forming today. Another hot spot ... May 25, 2017 ... Abstract. Mantle plumes are buoyant upwellings of hot rock that transport heat from Earth's core to its surface, generating anomalous regions of ...

This study aims to improve understanding of climate-landscape linkages using hotspot volcanic islands in the tropics as natural laboratories. A volcanic hotspot is where magma pushes up from deep in the Earth's crust or mantle, and creates a volcano. 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 ... ... volcanism that is trailed by an age-progressive hotspot volcano chain. However, a range of observations call for significant extensions to classical theory ...
