What is the physical composition of the asthenosphere?

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. Various definitions of the boundary reflect various aspects of the boundary region.
