2D and 3D Finite Element Restorations of Geological Structures with Sliding Contact Along Faults
Abstract : A fully implicit finite element method is developed for the restoration of sedimentary basins. Internal deformation
is distributed with a linear hyper-elasticity constitutive law. Deformation is also accommodated by large sliding
along faults. This mechanism is represented by a frictionless bilateral contact algorithm between deformable
bodies. Application are shown with 2D forward or backward models of thrust related folding with multiple
intersecting discontinuities. An example demonstrates how this restoration algorithm enables to detect
misinterpretation in the structural model. One advantage of the method is to allow 3D modeling, as shown by
the restoration of a Miocene anticline in the Iranian Zagros thrust belt. The main interest of this method will be to
facilitate the coupling between restoration and forward modeling.
