Abstract

After having recalled facts which leaded the CEA to use new geochemical techniques for the prospecting of uranium deposits through sampling and analysis of soils and waters, the author describes the organisation and methods implemented for this prospecting activity: team composition for sampling and analysis, role of each engineer and technician in the prospecting stages (preliminary study, routine prospecting, result interpretation), sampling and analysis processes. He also reports campaigns of geochemical prospecting: study of the La Chapelle Largeau deposit (objectives, geological context, preliminary study, routine prospecting, study of geochemical anomalies), tactical research on Verneix indices (study of radioactivity anomaly discovered by radio-prospecting), strategical searches in a non prospected area in the South of Avallon. The author discusses the issues of efficiency and cost price of this geochemical prospecting technique in soils and in waters. Appendices present the equipment and operation modality for soil sampling, and for soil sample preparation, and principles, equipment and products for soil analysis and for water analysis [French] A la suite des resultats satisfaisants obtenus dans la recherche de methodes de dosage adaptees au cas de l'uranium, la Direction des Recherches Minieres du Commissariat a l'Energie atomique a decide, en decembre 1954, d'utiliser, conjointement avec les  More>>

Ces applications pratiques ont ete confiees a une Section de Geochimie dont l'organisation, les moyens en personnel et en materiel, ainsi que les methodes de travail, font l'objet d'un expose detaille. Quelques exemples de prospection, en France metropolitaine, montrent la nature des problemes poses (etude d'un gisement connu, recherche tactique sur des indices, recherche strategique dans une region non prospectee), les methodes utilisees pour les resoudre et les resultats qui ont ete obtenus. En conclusion, l'auteur souligne ce qu'apporte l'utilisation de la methode geochimique de prospection tant au point de vue pratique de la recherche puis de l'etude des gites qu'au point de vue economique ou grace a ses possibilites et a son prix de revient interessant, cette technique nouvelle peut rivaliser avantageusement avec celles utilisees jusqu'ici. Malgre leur but essentiellement pratique, ces recherches sont susceptibles d'apporter a la geochimie theorique un nombre considerable de faits et d'observations du plus grand interet. (auteur)}
