A schematic representation of the kinds of processes, properties, and boundary conditions modeled in a typical sandbox experiment. The primary components of the model are the backstop, materials within the progressively deforming wedge, and the basal detachment. The schema applies to both indenter and subduction models. Actual wedge deformation is not shown. Diagram is modified from Graveleau et al., (op cit), Figure 14.

Analogue models of orogenic wedges

This post focuses on sandbox models and what they tell us about the mechanics and kinematics of orogenic wedge development. […]
