| 释义 | lithosphere noun environment specializeduk /ˈlɪθ.ə.sfɪər/ us /ˈlɪθ.ə.sfɪr/ [ C ] the solid outer layer of a planet: The interior of the Moon cooled and the lithosphere became rather thick. the lithosphere [ S ] the solid outer layer of the earth: （地球）岩石圈 The lithosphere is about 100 kilometres thick and is rigid and strong. Parts of the lithosphere could be moved apart by the sideways movement of the currents underneath. See also asthenosphere the atmosphere biosphere exosphere hydrosphere ionosphere mesosphere stratosphere thermosphere troposphere Related word lithospheric About two-thirds of the Earth's outer rigid shell is made of an oceanic lithosphere consisting of reduced mafic and ultramafic rocks. The lithosphere experiences flexure, just as a springboard does when a diver walks along it. The lithosphere essentially floats on the asthenosphere.

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.
