GeoMod2004 Analogue - Numerical model comparisons

Numerical and analogue models are widely used to investigate the evolution of geological structures as, for example, fold-and-thrust belts or sedimentary basins. The underlying assumption with both methods is that their results approximate the development of structures in the real Earth in a reasonable manner. We may then expect that the results of analogue and numerical models look at least similar if applied to the same setup. This is what motivated us to initiate a series of analogue and numerical model comparisons. The results of the GeoMod2004 shortening and extension experiments have been published in Analogue and Numerical Modelling of Crustal-Scale Processes , Buiter, S.J.H. and Schreurs, G. (eds), Geological Society, London, Special Publications, 253 :
