Exempel på lithospheric

• Heat flow measurements have been employed to map variations in lithospheric thickness.

• The regional subsidence in the Danish and North German basins may have been caused by lithospheric cooling.

• Chains of oceanic volcanoes occur when lithospheric plates drift over a" hotspot".

• Sea-floor spreading and continental drift were seen as involving these lithospheric plates rather than just oceanic or continental crust.

• The evidence, including that of xenoliths carried in the magmas, supports the idea of melting of old metasomatized lithospheric mantle, usually associated with rifting tectonics.

• An important consequence of this 'magmatic under plating' is that it reduces the density of the lithospheric column in which it is emplaced.

• An additional influence of lithospheric flexural stress caused by intrusive and volcanic loading cannot be ruled out, however.

• The second model involves derivation of the melts from a depleted lithospheric mantle source which was contaminated by subduction components.

• The break-off and detachment of the subducted oceanic slab and the accompanied upwelling of the deep asthenospheric mantle might lead to post-orogenic lithospheric extension.

• There is also little discussion of lithospheric scale modelling of the dynamics of mountain belts.

• Further east, however, two sets of observations support the existence of coeval lithospheric extension.

• The difference between this model and active rifting is that the convective upwelling is a consequence, not a cause, of lithospheric thinning and rifting.

• A certain degree of coherence should exist within the crust and between the crust and lithospheric mantle.

• Such melts thus preserve the best evidence for the composition of sub-continental lithospheric mantle, particularly for the origin of mantle enrichment.

• A 'heat flow province' may be regarded as a region with a certain mantle heat flow and a similar lithospheric thermal structure.

• Consequently, the lithospheric mantle was highly affected by an old continental component.

• Tracking changes in sub-continental lithospheric mantle through time.

• Lithospheric buoyancy and collisional orogenesis: subduction of oceanic plateaus, continental margins, island arcs, spreading ridges, and seamounts.
