3D modeling

3D modeling is a tool for building 3D subsurface models of geological structures accounting for available data.

The 3D modeler used in Geosciences Rennes is gOcad. Gocad is a 3D modeler specifically developped for geological application since 1989. It has been initially developped at Nancy, in the LIAD laboratory. Gocad is now a Paradigm product.

Examples of geological application of gOcad may be found here in the CRPG web site, my previous laboratory.

At Rennes, gOcad is used for :

Research :

  • Modeling of offshore and intracontinental basins around and in Africa, in order to quantify sediment supply evolution around Africa since the Permian
  • Kilometric -scale modeling of the deformation in the N of cap Corse, France
  • Modeling of the Corinth rift fault network and sedimentary architecture
  • Developpement of plugins (e.g. georeferencing maps in gOcad)

Teaching :

  • About 20 h for the 1st year of Geosciences Master (structural modeling)
  • About 3h for the 2nd year of Geosciences Master (example of application)
  • 6 Master or PhD students working on the above subjects
