WebLithospheric extension is attributed to processes related to plate tectonics. 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. portland oregon new years 2022 fireworksWeb11 apr. 2024 · Dating the timing of ductile shear deformation is critical to the understanding of complex, multi-episode kinematics that commonly occur within the study of continental tectonics. The Tan-Lu Fault zone in East China is a lithospheric discontinuity that records multistage sinistral strike-slip shearing during Mesozoic time. optimize healthcare llcWebLarge-scale folding is a key mechanism of lithospheric deformation and has been described in many parts of the Earth, both for the continental and oceanic lithospheres.
