Are there different types of mantle plumes with varying properties?

A 30 foot slice of volcano looks like most other rocky terrain. Unless it ... hotspot, volcanoes would form. They would build enormous shield-shaped ... Jan 6, 2022 ... The team found that nearly half of hotspot volcanoes are substantially hotter than mid-ocean ridge volcanoes, as conventional thinking suggests. La Grille, Unknown - Evidence Credible, Comoros Hotspot Volcano Group, Shield ; Karthala, 2007 CE, Comoros Hotspot Volcano Group, Shield ... Hotspots at the seafloor create subsea volcanoes; building upward, they ultimately become volcanic islands. Hotspots are stationary but the crusts above them ... The hotspots are creating volcanoes. Since the hotspot is mostly stationary when the tectonic plate moves it creates a new volcano. The action of the plates ... A volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. High heat and lower pressure at the base of the ... May 10, 1995 ... Here we show that recent estimates for the volume of hotspot volcanism and the size of the swell suggest a shared origin: swell relief is ... Jan 1, 2020 ... We examine swell bathymetry and island drowning at 14 hotspots and find a correspondence between island lifespan and residence time atop swell bathymetry. Jan 1, 2020 ... Island lifetime depends on the rate and magnitude of island subsidence, which, in turn, depends on the dynamics of the oceanic lithosphere and ... Feb 24, 2012 ... Summary · Volcanoes grow above hotspots, which are zones of melting above a mantle plume. · Hotspot volcanoes are better able to penetrate oceanic ...
