WebDelamination occurs when the lower continental crust and mantle lithosphere break away from the upper continental crust. There are two conditions that need to be met in order for delamination to proceed: The lower lithosphere must be denser than the asthenosphere. WebA variety of geophysical observations suggests that the upper portion of the lithosphere, herein referred to as the elastic plate, has long-term material properties and frictional strength significantly greater than the lower lithosphere.

WebNiels Bohr. The lithosphere forms the outer (typically, 50–300 km thick) rigid shell of the Earth. It includes the crust and, in general, some non-convecting part of the upper mantle called the lithospheric mantle (Fig. 1.1). Oceanic lithosphere is recycled into the mantle on a 200 Ma scale, whereas the study of the continental lithosphere is ...
