Considering the dimensions of these gravity minima and existing geological, aeromagnetic, magneto-telluric, seismic and well data, we suggest that fault-bounded sedimentary basins lie north of the CASZ in central and eastern Sudan. 参 考 资 料 The < 10 km cumulative Mesozoic extension within the African plate north of the CASZ implied by these studies, however, will not change significantly current plate models for the break-up of Africa and South America.We use cookies to help provide and enhance our service and tailor content and ads.

The Central African Rift System (CARS) and its associated CASZ (Shear Zone) comprise the failed arm of the Gulf of Guinea triple junction in South America-Africa breakup. Search for other works by this author on: These data indicate a thinned lithosphere beneath the Central African Shear Zone, where seismologically defined asthenosphere upwells from a depth of about 190 km to about 120 km in a relatively narrow belt.
The central block, which is 2 per cent slower than the adjacent blocks, roughly corresponds to the Central African Shear Zone. King This transcontinental shear zone is a major crustal discontinuity extending from north-eastern Brazil into CAR (Fig. English: Sketch map of Central African Shear Zone. The inset in Figure 3 (from Fairhead et al., 2013) shows how the pole of rotation describing the motion of the Adamawa Plateau, as an individual uplifted area, is explained by the interaction of a regional anomalous upper mantle associated with the West African Rift System, and the Central African Shear Zone, which provided a conduit for heat flow to the surface.

The Central African Shear Zone (CASZ) is a 4000-km-long, NE-striking wrench fault system, along which motion occurred during the break-up of Gondwanaland, but its location in central Sudan was poorly defined. King Solomon III Hence, there is a link between the present study and the previous ones, as it shows that the fault oriented NE-SW was derived from the tectonic event that has occurred during the Pan-African orogeny and it is directly aligned with the Central African Shear Zone (CASZ). ...

The Central African Shear Zone (CASZ) is one of the most familiar examples.
