文摘
- •
Lithosphere deformation modes evolve during continental rifting leading to breakup.
- •
Lithosphere deformation evolves from wide to narrow widths, and it includes jumps and continuous lateral migration.
- •
Buoyancy induced upwelling initiates earlier melting, speeds up lithosphere thinning while maintaining weaker subsidence.
- •
Melt retention is necessary for the formation of magma-poor rifted margins.
- •
A diachronous deformation evolution is preferred for the Iberia-Newfoundland, consistent with the rift northward propagation.
