The engineer will be in charge of building 3D geological models from various data acquired during exploration campaigns targeting metal deposits in Canada and carried out by Orano, a mining company partner of the project. The construction of these geological models will be carried out using specific softwares, including the Gocad and SKUA-Gocad geomodelers.To do this, the engineer will simultaneously constitute data libraries of the different properties (physical, chemical, mineralogical or spectral) from which the 3D models will be produced. The generation of these data libraries will rely in particular on the application of machine learning methods, and the use of dedicated software suites, including those developed by Mira Gesocences (Gocad Mining Suite including Geoscience Analylist and Geoscience Integrator). The aim is to guarantee the updating of 3D geological models through the administration of geoscientific data management systems. These models will be used by the geological and geophysical modeling teams active within the GeomIn3D Chair with which the engineer will interact constantly. This work will be carried out within the framework of the GeomIn3D industrial chair financed by the ANR and the company Orano and supported by the GeoRessources (Nancy)-ITES (Strasbourg) and Orano laboratories.


-Construction, evaluation and update of 3D integrated geological models of Orano's mining exploration zones in Canada. Access to these 3D models will be a common thread of the GeomIn3D project because it will serve as a reference for geologists, geophysicists and modelers working within this chair and with whom the engineer will interact constantly.
- Development of a model and constitution of data libraries for the generation of 3D models. This phase will be carried out in close collaboration with the geochemists and geophysicists in charge of the various tasks of the GeomIn3D project and the geologists, geophysicists and “datascientists” from Orano. An inventory of the equations and calculation routines useful for the valuation of the various properties evaluated will be carried out and the opportunity to include them in the libraries will be defined with the industrial partner by the qualified experts.
- Definition of the variability of parameters and thresholds corresponding to the delineation of geological zones of interest for the discovery of metals. Considering that these parameters and their values ​​have a significance dependent on the geological environment and the presence or absence of metals, several libraries will be constituted and qualified according to the potential of the zones by the competent persons.
- Implementation of libraries, applicability tests and feedback. As batches of data are acquired and reprocessed, these libraries will be supplemented and tested. The feasibility of their extension to other batches of data from the natural analogues studied and of sharing with other players in the exploration of georesources may be considered during this phase.
-Production of technical developments in order to guarantee direct referencing of the geological material sampled and preserved with Orano's drilling databases and cartographic processing and modeling software

Work Context

This work will be mainly done within the laboratoire GeoRessources of the Université de Lorraine, located in Nancy (France). Regular and frequent missions will be carried out in Strasbourg (ITES) and Chatillon (Orano). Missions will be done at the Orano center in Saskatoon (Canada). GeoRessources is part of the Université de Lorraine (http://welcome.univ-lorraine.fr/), which is one of the leading higher education institutions in Europe with more than 55,000 students and 60 research laboratories. The Université de Lorraine ranks 13th in the Shanghai 2021 ranking in the "Mines and Mineral Engineering" category and 1st European university in this field of activity. The Department of Earth Sciences is one of the largest in Europe, with 4 laboratories hosting more than 300 researchers and 1000 students. Georessources is the French academic laboratory of reference for the study of deposits, with nearly 200 people (http://georessources.univ-lorraine.fr/), with long-term collaborations with major mining and oil companies. It is considered one of the reference centers for academic research on uranium deposits, with more than 40 years of research on this subject.
