Abstract

Geologist need often to construct 3D models and to check their coherency. Such coherence could be analyzed on the current geometry but could also be quantified through restoration. To achieve this restoration, i.e. the search for an initial geometry with a realistic deformation pathway between the initial and the final geometries, one needs appropriate tools. These include the classical cross-section balancing, the surface unfolding and the volumetric restoration. All these tools now exist, however the obtained results may strongly depend of the used methods. It is rather well known for the cross-section and surface restoration (flexural slip versus simple shear), let see now in 3D the difference between the algorithms. The various tools used mainly an elasticity behavior to approach the volume conservation but there are various way to implement this method. Infinitesimal strain, Finite Rotation, Finite Strain, implicit, explicit... What it means? And what are the differences on the results?
