Iceland Plume

The Iceland Plume is a postulated upwelling of anomalously hot rock in the Earth's mantle beneath Iceland. Its origin is thought to lie deep in the mantle, perhaps at the boundary between the core and the mantle at ca. 2880 km depth. Opinions differ as to whether seismic studies have imaged such a structure. In this framework, the volcanism of Iceland is attributed to this plume, according to the theory of W. Jason Morgan.

Famous quotes containing the word plume:

    In some of those dense fir and spruce woods there is hardly room for the smoke to go up. The trees are a standing night, and every fir and spruce which you fell is a plume plucked from night’s raven wing.
    Henry David Thoreau (1817–1862)
