These processes are well understood at mid-ocean ridges, where most of Earth's volcanism occurs. It is less commonly recognised that the plates themselves deform internally, and can permit volcanism in those regions where the deformation is extensional. portfolioanalyse cash cow

WebDue to their expressive lithospheric thickness and a high degree of Fe depletion, cratons have a high P-wave velocity, which enables a good study though seismic tomography methods. On the other hand, the SCLM beneath a craton is not homogeneous, since cratons were formed through accretions of lithospheric blocks. WebThe lithospheric plates in our models have an effective elastic thickness, which provides an upper bound for rapid processes, like slab detachment, to the surface deformation of lithosphere with a more realistic rheology. The surface topography which develops during subduction is compared with the topography shortly after
