Unraveling the Mystery: Scientists Discover Cause of Earth's Largest Continental Rift's Unusual Deformation

Scientists have used 3D thermomechanical modeling to uncover that the African Superplume, a massive mantle upwelling, is responsible for the unusual rift-parallel deformations observed in the East African Rift System. This adds complexity to the debate on the primary forces driving the rifting, suggesting a combination of lithospheric buoyancy forces and mantle traction forces. The research findings provide new insights into the processes involved in continental rifting and may help scientists better understand the breaking of continents.

Unraveling the Mystery of Earth's Largest Continental Rift Deformation.

Computer models confirm that the African Superplume is responsible for the unusual, rift-parallel deformation observed beneath the Earth's largest continental rift system, the East African Rift System. The deformation that comes with continental rifting usually follows predictable directional patterns in relation to the rift, but the East African Rift System has both rift-perpendicular and rift-parallel deformations. The study's findings could help clear up scientific debate on which plate-driving forces dominate the rift system, accounting for both its rift-perpendicular and rift-parallel deformation: lithospheric buoyancy forces, mantle traction forces, or both.
