GeoRessources is a « Unité Mixte de Recherche », a research laboratory based on the consortium of CNRS, Université de Lorraine and CREGU. GéoRessources is devoted to fundamental research on geological resources : ore deposits, hydrocarbons (conventional as well as unconventional), geothermal energy, underground reservoirs (hydrocarbons, sequestration of acid gases).
Our organic geochemistry laboratory is performing research on all aspects of organic matter associated to geological resources. It concerns the characterization of geological samples, experimental investigation on the reactivity of fossil organic matter, modeling of reactivity. All measurements and experimental results are interpreted as to better understand the origin and fate of organic matter in geological settings, either as natural occurences (e.g. petroleum, ore deposits) or as material for usage (e.g. geological barriers, underground storage). Current research projects deal with the Re-Os contents of petroleum and their use as geochronometer to date events affecting petroleum, the geochemistry of water-oil-rock interactions in petroleum systems, the role of organic matter in various uranium deposits. Georessources is providing to the Ecometals project expertise on organic geochemistry: analyses of organic matter in the initial ore, during or after processing.
