Abstract
The gold content of sixty geochemical reference samples has been determined by atomic absorption spectrometry using a graphite furnace atomizer after digestion of sample with aqua regia and extraction of gold as chloride by methylisobutylketone. A comparison with published data shows clearly the need for much more data on most samples before consensus values could be assigned.La teneur en or dans soixante échantillons géochimiques de référence a été déterminée par le spectromètre d'absorption atomique équipé d'un four à graphite. L'échantillon a été mis en solution avec de l'eau régale et l'or extrait avec du methylisobutylketone. Un examen des données publiées sur l'or montre qu'il faut davantage de résultats pour fixer des valeurs de consensus dans la plupart des échantillons.Keywords
