Witrynaridges have a more pronounced thinning of the lithosphere. Finally, the offset at which Dd goes to zero is controlled by the geometry of the base of the lithosphere which limits the width of the region above the solidus. Fast spreading ridges have thinner lids which allow melting due to the perturbed flow to extend further away from the ridge ... Witryna23 wrz 2010 · The Earth has distinctive convective behaviour, described by the plate tectonics model, in which lateral motion of the oceanic lithosphere of basaltic crust and peridotitic uppermost mantle is decoupled from the underlying mechanically weaker upper mantle (asthenosphere).

More extensive decompression melting … Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle.
