The composition of the asthenosphere

WebJan 28, 2011 · The nature and extent of the regional lithosphere–asthenosphere interaction beneath Ireland and Britain remains unclear. Although it has been established that ancient Caledonian signatures pervade the lithosphere, tertiary structure related to the Iceland plume has been inferred to dominate the asthenosphere. To address this apparent ... WebThe asthenosphere has a convection current, made by magma swirling around in a circular motion, from top to bottom. The convection current is what makes the plates move. The asthenosphere is part of a gigantic layer that takes up a full 2/3 of the Earth's radius: the mantle. The asthenosphere is part of the upper mantle, closest to the crust.

The asthenosphere extends from an upper boundary at approximately 80 to 200 km (50 to 120 miles) below the surface to a lower boundary at a depth of approximately 700 kilometers (430 mi). The lithosphere-asthenosphere boundary (LAB ) is relatively sharp and likely coincides with the onset of partial melting or a change in composition or anisotropy.
