Thèmes de recherche
Je cherche à comprendre les conditions de formation des principaux ciments et fractures minéralisées observés dans les bassins sédimentaires, en particulier les bassins d'avant-pays, ainsi que dans les orogènes. Je me base essentiellement sur des observations de terrain, des outils pétrographiques, géochimiques et isotopiques.
I aim to understand the formation conditions of major cements and mineralized fractures observed in sedimentary basins, particularly foreland basins, as well as in orogenic belts. My research primarily relies on field observations, petrographic, geochemical, and isotopic tools.
