Abstract

On the basis of data collected in Lac Léman (Switzerland), we discuss a few of the fundamental concepts that underlie geochemical investigations: the carrier substance, the natural background level, the grain-size effects and the areal variability of geochemical associations.

The key role played by the statistical methods in expressing, testing, and refining these concepts is emphasized.

Résumé

En se basant sur des données récoltées dans le Léman, on discute quelques-uns des concepts fondamentaux qui sous-tendent la méthodologie géochimique: le support sédimentaire des traces, la teneur naturelle, l’effet granulométrique et la variabilité spatiale des associations géochimiques.

On souligne également le rôle capital joué par les méthodes statistiques dans l’expression, la mise à l’épreuve et raffinement de ces concepts.
