Lithosphere strength
Weboverall lithosphere strength is located in the seismogenic upper crust instead of within the uppermost mantle. This conception of lithosphere rheological layering is however in … WebStrength appears to be concentrated in the crustal upper 7–12 km of the lithosphere. This finding is in very good agreement with the depth distribution of seismicity. Earthquake hypocenters are restricted to the uppermost crustal levels, suggesting that brittle deformation of the lithosphere is limited to depth of 5–15 km ( Tóth et al. , 2002 ).

WebA majority of continental elastic thickness estimates, especially those from extended regions, are relatively low and in the range of 0-20 km. Only in the cool cratonic interiors does the continental lithosphere appear capable of showing any degree of long-term strength. Web16 jul. 2024 · As an important part of the continental lithosphere, the continental lower crust can influence and control many important geodynamic processes, which are of great significance to the evolution of the lithosphere. Extensive plastic deformation is common in continental lower crust. There have been many studies focusing on the rheology of the …
