Web25 okt. 2024 · A 100 km thickness is imposed as the minimum continental and maximum oceanic characteristic thickness. It should be kept in mind that material properties such as viscosity vary continuously throughout the depth of the lithosphere, so the definition of thickness may vary.
WebABSTRACT We have investigated the anelastic dispersion and attenuation of P- and SV-wave scattering by nonisothermal inclusions of finite thickness. The inclusions, which are aligned and sparsely embedded in an isotropic medium, induce an initial static stress field (acoustoelasticity) and a nonlinear dependence of the velocities on this stress. Moreover, … WebSedimentary thickness varies from 0–3 km in stable craton to 10–20 km in extended regions. Typical Moho depths are 44–48 km in Archean crust …
