Continental extension may occur in two main different modes, narrow and wide rifting, which
mainly differ in the width of the deformed region. A third mechanism, the core complex, has …

The large scale structure of the earth is caused by geodynamic processes which are
explained using energetic, kinematic and dynamic descriptions. While" geodynamic …

Since Vening‐Meinesz's realization that the East African Rift represented an extensional, not
compressional, feature and since the widespread acceptance of plate tectonics two decades …

Stretching and thinning of continental lithosphere during rifting and initiation of seafloor
spreading cause upwelling of mantle rocks into a pressure/temperature environment where …

The initiation of the Afro-Arabian Rift System on three nearly straight segments occurred
shortly after massive amounts of basalt poured out of the triple junction of those segments in …

The complex plate boundary between Arabia and Africa at the northern end of the Red Sea
includes the Gulf of Suez rift and the Gulf of Aqaba—Dead Sea transform. Geologic …

The physical conditions required to provide for the tectonic stability of cratonic crust and for
the relative longevity of deep cratonic lithosphere within a dynamic, convecting mantle are …

Convection in the upper mantle can give rise to normal stresses on the base of the
continental lithosphere that may cause localized elevation of its surface and extensional …

In the central Andes, giant porphyry copper deposits of similar ages group into discrete
geographic clusters that are regularly spaced and aligned within orogen-parallel belts. This …

Lithospheric necking and magmatic intrusion are thought to be the primary processes
responsible for narrow continental rifts. There is much less agreement as to the cause of …
