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.

Webdiastrophism, also called tectonism, large-scale deformation of Earth’s crust by natural processes, which leads to the formation of continents and ocean basins, mountain systems, plateaus, rift valleys, and other features by mechanisms such as lithospheric plate movement (that is, plate tectonics), volcanic loading, or folding. The study of … WebA comparison is made with heat flow variations in order to assess the importance of lithospheric rheology in the style of extensional deformation. Three different rift sectors can be identified. The southwestern rift sector is characterized by strong gravity and topography contrasts marked by two major crustal faults and diffuse seismicity.

Web9 apr. 2024 · Orogenic processes can cause modification of the lithospheric mantle, in some cases leading to severe destruction and thinning of the lithospheric mantle, and thus crust-mantle decoupling.
