Lithospheric extension

Web19 dec. 2008 · Extension of the lithosphere is modelled numerically using a 2-D plane-strain finite element method for viscous-plastic creeping flows. The evolving temperature and pressure fields within the model are coupled to an algorithm that predicts the amount and timing of decompression melting of upwelling mantle.

Web30 mrt. 1996 · However, lithospheric extension also increases the geothermal gradient serving to weaken the lithosphere. The rate of extension is critical in determining which of these processes predominates. WebThe oceanic lithosphere record of plate divergence only extends back some 200 Ma, corresponding to a little over 4% of Earth's 4.56 Ga history. However, the record for continental lithospheric extension leading to break-up and sea-floor spreading extends back to the Archaean. Webshear extension of the lithosphere is modeled as occurring along a straight shear zone. Two parameters define the simple shear model: the dip of the shear zone and its width. Likewise, the pure shear model is defined by two variables: the initial width of a vertical zone of pure shear extension and the rate of change of its width. reading festival line up 2004
