Abstract
This system comprises means for standardizing the detected gamma spectrum and processing it by a reference spectrum. The lithology and/or the nature of the ores are determined, by a processing means, by comparison between the standard recorded spectrum and lithology and/or ore spectrum models contained in a library. The ore content, density and porosity can also be determined without supplementary measurements on the basis of the lithology and the nature of the ores.
