Geochemistry teams focus their research on different geochemical approaches to study organic and inorganic compounds in solid and liquid matrices such as rocks, soils, water in a modern and ancient environment.The research activities are organized around several themes :
- Aqueous geochemistry: transfer of metal ions, organic compounds and their metabolites. Thus, the transport and fate of these contaminants in groundwater and surface water are of particular importance for the hydrological and hydrogeological cycle.
- Environmental organic geochemistry using organic matter that provide information ranging from the origin of natural organic substances to the metabolic processes and bio-signatures.
- reconstruction of the wetland environment and climate using biomarkers
- Biomass development: solid organic waste has been shown to cause greenhouse gas emissions and climate change.. The valorization of the biomass can produce bioenergy and soil fertilizers.
- Source rock evaluation : the geochemical exploration and evaluation of the source rocks using geochemistry and paleoenvironmental geology allows to understand the processes of genesis, migration and accumulation of hydrocarbons. The evaluation of the reserves of hydrocarbons contained in the primary and secondary porosity of the source rock and the study of the history of burial, lead to characterize the provinces of unconventional hydrocarbons of gas or shale oil.
