The Service d'Analyse des Roches et des Minéraux (SARM) is the CNRS Analytical Research facility which is part of the Centre de Recherches Pétrographiques et Géochimiques (CRPG).
The Service was founded in 1972, to harmonise the analytical potential of the CRPG with the needs of the geological community in France. Today, the SARM is an important research facility of INSU and counts about fifteen technicians and engineers. The SARM has an analytical capacity of more than 6000 samples per year. About 60 different elements are analysed in its laboratories.
It comprises :
- three analytical laboratories (spectrochemistry, mineral chemistry, isotope geochemistry),
- an administration office,
- a technical support unit,
- a grinding workshop.
The SARM has at his disposal several spectrometers, element analysers and other instrument accessories for sample preparation and analytical work, as welle as a computer room for data base.
Although the Service d'Analyse des Roches et des Minéraux is a CNRS laboratory, a quarter of the analyzed samples are from other research public organizations and private companies.
Since 1963, under the initiative ok K. Govindaraju, the SARM prepares and characteries geological reference materials for geochemical analyses. These "GEOSTANDARDS" are distributed around the world.
