This suggests that the deformation of the lithosphere is strongly controlled by interfering vertical and lateral heterogeneities. First, the elastic response of the lithosphere to loading is included. This rheological layering raises a series of fundamental questions on the mechanics of the lithosphere. Derivation of some modern arc magmas by melting of young subducted lithosphere. As such, it provides a strong conceptual basis for illustrating the linkages between atmosphere, lithosphere, hydrosphere and biosphere. It will be less useful for those working on oceanic lithosphere, hydrocarbon geology or mineralization processes. Thus, fluids associated with subduction may have been responsible for triggering partial melting of lithosphere already experiencing decompression as a result of extension. Either of these mechanisms can cause the hot asthenosphere to rise close to the metasomatized lithosphere, initiating melting. There is considerable debate about the range of values of e for continental lithosphere. Instead, our results suggest that convective drawdown plays a role by pulling lithosphere toward the zone of maximum shortening. In particular, is the source of within-plate basaltic magmas in an extensional setting the lithosphere, convecting asthenosphere or both? The volume and composition of melt generated by extension of the lithosphere. The strain rate at which the lithosphere was stretched is taken as a standard 10-15sec-1. Selecting 100 km gives a conservative estimate as this area has the thinnest lithosphere and will produce the least lamprophyre on rifting. It is clear that such narrow cracks would be incapable of transporting significant volumes of magma through the lithosphere. The volume and rare earth concentrations of magma generated during finite stretching of the lithosphere. These basalts can provide an integrated record of the different processes involved in the evolution of the continental lithosphere. The extension of lithosphere accompanied with the upwelling of asthenosphere may be the key factor for the coeval magmas with different sources. However, the exact geochemical signature of the lithosphere remains at issue. This paper presents models of the thermal structure of extending lithosphere to investigate the conditions under which anatexis could occur. The model produces the most granite if hydration was coeval with transtension and penetrated the lithosphere along pre-existing lines of weakness. In contrast, mantle lithosphere thinning produces a negligible change in the upper crust. Radial extension might be due to the loads produced by the volcanic shields on the lithosphere, magma inflation or a combination of both processes.
