(eg,Walker, 1999), led to the definition of rift zones in the Canaries as a linear clustering of surface vents fed bydyke swarmsfrom the depth (Fig. 1.26). Walker argued that these structures may be an invariable characteristic of ocean volcanoes, and this appears to hold true, at least...

The inversion of the Deep Tow data, near the seafloor, provides a high-resolution definition of the location of the tip of the propagating rift, at 2°38.1′N, 95°30.0′W.Stephen P. MillerDepartment of Geological Sciences and Marine Science InstituteR. N. Hey...
In our model, strain is largely E-W extensional across the Eastern and Western Branches with larger magnitudes of strain rates within deforming zones and low strain rates in rigid plate interiors, as expected per our definition of rigid and deforming zones. Figure 4D is a comparison of the ...

The Great Rift Valley is a huge fracture in the crust of the earth in the eastern part of Africa. Crustal rifts are found all over the world, but the one in East Africa is the largest. The rift is a complex series of faultlines that runs from the Red Sea down into Mozambique. ...
(see Fig.2for the definition of parametersf,α,a, andbthat define the mobile belt geometry). Under the assumption of thermal steady state, the thinner mantle lithosphere in the belts leads to higher temperatures in the lithosphere, which in turn decrease its strength (compare the first two ...
To this, we add a definition of rift-induced processes, i.e. processes leading to compositional changes during rifting (e.g. serpentinization or decompression melting). Using this approach, we focus on 3 well-studied rift systems that are the Alpine Tethys, Pyrenean–Bay of Biscay and Iberia...
