Lithospheric thinning
WebRemoval and thinning of cratonic lithosphere is believed to have occurred under different tectonic settings, for example, near subduction zones and above mantle plumes. WebThinning of the lithosphere by heat carried convectively to its base is a possible mechanism for the initiation of continental rifting. The lithosphere-asthenosphere boundary marks the …
