The crust of the Earth records the deformational processes ofthe inner Earth and the influence of the overlying atmosphere,The state of the Earth's crust at any time is therefore theresult of internal and external processes, which occur on differenttime and spatial scales. In recent years important steps forwardin the understanding of such complex processes have been madeby integrating theory and observations with experimental andcomputer models. This volume presents state-of-the-art analogueand numerical models of processes that alter the Earth's crust.It shows the application of models in a broad range of geologicalproblems with careful documentation of the modelling approachused. This volume contains contributions on analogue and numericalsandbox models, models of orogenic processes, models of sedimentarybasins, models of surface processes and deformation, and modelsof faults and fluid flow.
