Web6 apr. 2024 · Amphibole is an important component in the middle to lower crustal rocks, and its deformation behaviors reflect the mechanical strength, rheological and physical properties of lithospheric crust. However, the detailed deformation characteristic and formation of CPOs, as well as deformation mechanisms in amphibole are highly debated. Web15 dec. 2015 · We present a new thermal and strength model for the lithosphere of Mainland China. To this purpose, we integrate a thermal model for the crust, using a 3‐D steady state heat conduction equation, with estimates for the upper mantle thermal structure, obtained by inverting a S wave tomography model.
