WebCrustal rheology controls the style of rifting and ultimately the architecture of rifted margins. Here we review the formation of three magma-poor margin pairs, Iberia-Newfoundland, the central segment of the South Atlantic Rift, and the South China Sea by integrating observational data into a numerical forward modelling framework. WebMoreover, the driving forces of plate tectonics cannot exceed the integrated lithospheric strength. This provides an important constraint on the geodynamics of oceans and continents.

Role of Lithosphere Rheology on Rift Architecture SpringerLink

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. WebLateral variations in lithospheric strength have been adopted often in flexural modeling (both 2D and 3D) to better fit the observed basement deflections, typically supported by gravity data. This approach provides essentially a "snap-shot" of the role of lithosphere strength in determining the present day geometry.
