WebLithospheric extension is attributed to processes related to plate tectonics. From Wikipedia When the upper lithospheric crust experiences extensional pressures, the brittle crust … Webthe extension value estimated from preservation of the volume of the crust is about 12 km [Bois, 1993]. As it has been shown that the northern segment was affected by two distinct periods of extension, the extension value resulting from the West European rift episode only is probably about 12 km. Thus the extension rate deduced

WebLithospheric mantle stratification is a common feature in cratonic areas which has been demonstrated by geophysical and geochemical studies. The influence of lithospheric mantle stratification during craton evolution remains poorly understood. Web6 jun. 2024 · Preliminary lithospheric thinning was induced by the extension of the NCC resulting from trench retreat of the Paleo-Pacific plate at ~140-120 Ma. Then, decompression melting of the lithospheric mantle caused pervasive melts in the weakened lithospheric mantle, resulting in the lithospheric mantle having a low viscosity …

Web[2] Lithospheric modification during continental rifting is an axiomatic consequence of plate tectonic processes. The processes whereby the continental crust is modified by magmatism during the progressive evolution from continental rifting to seafloor spreading, are however poorly constrained. Web10 dec. 2024 · We can hardly propose a constrained lithospheric thickness beneath the MNM rift arm based on our velocity density contrasts alone.
