Geodynamics of continental rift initiation and evolution
A continental rift is a nascent plate boundary where the lithosphere is thinned by tectonic
activity. Some continental rifts undergo extension to the point that they generate a new …

Displaced cratonic mantle concentrates deep carbon during continental rifting
Continental rifts are important sources of mantle carbon dioxide (CO2) emission into Earth's
atmosphere,–. Because deep carbon is stored for long periods in the lithospheric mantle …

Geodetic constraints on cratonic microplates and broad strain during rifting of thick Southern African lithosphere
Southern Africa is typically considered to belong to a single tectonic plate, Nubia, despite
active faulting along the southwestern branch of the East African Rift System. We analyze …

Tectonics and landscape of the Central African Plateau and their implications for a propagating Southwestern Rift in Africa
Abstract The Central African Plateau (CAP) covers a million square kilometers of African
lithosphere absent of recent volcanism and intense seismicity. Treating the CAP erosion …

A reappraisal of the H–κ stacking technique: implications for global crustal structure
SUMMARY H–κ stacking is used routinely to infer crustal thickness and bulk-crustal VP/VS
ratio from teleseismic receiver functions. The method assumes that the largest amplitude P …
