The Centre de Recherches Pétrographiques et Géochimiques (CRPG) is a laboratory of the CNRS gathering in one research center about a hundred people working in the field of Earth and Planetary Sciences. Located in Vandoeuvre-lès-Nancy, France, the center is a member of the Fédération de Recherche Eau-Sol-Terre (EST). The laboratory is organised in three research groups, Geochemistry, Petrology and Geodynamics. In addition, CRPG hosts the Service d'Analyse des Roches et des Minéraux and the Service National de Sonde Ionique of INSU. The journal Geostandards and Geoanalytical Research is published in association with CRPG. The research themes of CRPG include the following subjects:

Cosmochemistry, planets and primitive Earth
  • Early planetary evolution
  • Conditions of the formation of chondrules
  • Metal-silicate differentiation
  • Primitive Earth's crust
  • Precambrian environments
Surface of our planet
  • Tectonics and exhumation
  • Evolution of topography
  • Dynamics of physical and chemical erosion
  • Paleo-environmental tracers
  • Environments altered by human activity
Magmas and deep fluids
  • Magmatism on the ocean ridges
  • Tracers of magmatic processes
  • Mantle-crust exchanges and fluids in the lithosphere
  • Isotopic tracing and dating of ore deposits
  • Metallogeny and gems
Natural resources and pollution control
  • Determining the age of petroleum
  • Numerical modelling of geological objects
  • Stabilisation and storage of nuclear waste
  • Effects of incineration of household waste
  • Glass and crystal
CRPG was founded in 1953 at the initiative of Professor Marcel Roubault, by agreement between the CNRS and the Academy of Nancy. The Institut National Polytechnique de Lorraine and its school of geology, the Ecole Nationale Supérieure de Géologie, and the department of Earth Sciences of the Université Henri Poincaré, are CRPG's privileged research partners.
