Influence of indenter geometry on arcuate fold-and-thrust wedge: preliminary results of analogue modelling

Abstract

Analogue models, with sand and silicone, have simulated the progressive development of an arcuate foldand- thrust belt around indenters of different geometry, which moved along a straight translation path. In the most external part of the model, the resulting geometry of the deformed wedge is roughly independent of the indenter form. Deformation affected only the frontal part of the indenter and the lateral deformation zone around the latter was very narrow
