WebIn geodynamics, delamination refers to the loss and sinking (foundering) of the portion of the lowermost lithosphere from the tectonic plate to which it was attached. Mechanism [ edit] The outer portion of the Earth is divided into an upper, lithosphere layer and a lower, asthenosphere layer.

WebThe sediments that have accumulated in sedimentary basins during geological time represent a load on the lithosphere that should respond by flexure. Simple elastic and viscoelastic (Maxwell) plate models have been used to examine quantitatively the contribution of flexure to basin formation.
A lithosphere (from Ancient Greek λίθος (líthos) 'rocky', and σφαίρα (sphaíra) 'sphere') is the rigid, outermost rocky shell of a terrestrial planet or natural satellite. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of up to thousands of years or … Meer weergeven Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle.
