The main objective of the workshop is to enable the participants to build a 3D geological model while acquiring field data. The construction of the model is seen as a tool facilitating the interaction between the field work and the interpretation of the data. It is not a separated step that should be conducted when all the field data have been aquired.
The workshop includes therefore both field mapping in the Jura close to Neuchâtel (vallée des Ponts), coding of the data, and construction of a 3D model with the 3D Geomodeller software.
Furthermore, the course is designed to be a real workshop with a large part of exchanges between the participants and the teaching staff. All participants (modellers, field geologists, or mathematicians) are expected to learn from the expertise of the others with the common objective to better understand the geological structure of the site.
3D Geomodeller is a tool developed jointly by the BRGM and the australian company Intrepid Geophysics. The software allows the construction of 3D geological models from field observations and interpretation.
Its originality lies in the use of an implicit method in which the limits between the different geological objects are not modelled explicitely but are modelled as the iso-surface of an underlying potential.
All the method is based on a mathematical technique allowing the interpolation of the potential from all available field data. More details about the software and its advantages are described on its web site.
