Abstract

The thermal and isostatic consequences of continental deformation, particularly surface elevation, horizontal buoyancy forces and metamorphism in the crust, depend to a considerable extent on the way in which strain is distributed between the crust and the mantle lithosphere [1]. Since these vertical strains may be strongly "decoupled" by processes such as convective thinning or detachment of the lower thermal boundary layer [2], with the extent of this "decoupling" varying in space and time in an orogen [3], it is useful to parameterise the vertical strain on the scale of the crust, f{hook}c, and lithosphere, f{hook}1, respectively. We illustrate this parameterisation by considering the the..
