WebA lithosphere (from Ancient Greek λίθος (líthos) 'rocky', and σφαίρα (sphaíra) 'sphere') is the rigid, [1] 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 more. Web1 okt. 2015 · Abstract. Archean cratons consist of crustal granite-greenstone terrains (GGTs) coupled to roots of strong, buoyant cratonic lithospheric mantle (CLM). Although this association is unique to the Archean and formed from ca. 4.0 to 2.5 Ga, the origins of terrestrial cratons are debated. I propose that crustal plateaus, quasi-circular craton-like ... simply mediterranean visalia

WebSurface-wave tomography has shown that over most of Earth, deformation of the mantle lithosphere has oriented olivine crystals with the fast axis in the horizontal plane, but at depths centered at ∼150 km within cratonic continental-lithosphere roots, the fast crystallographic axis is preferentially aligned vertically. Web1 jan. 2013 · The lithosphere then stabilizes, until a second high density root forms, triggering further lithosphere removal (Fig. 9 c).
