Résumé : A 17 variscite beads set, buried in the Salpêtre cave in Pompignan (Gard, France) constitutes a unique Middle Neolithic set of ornaments in the southern France. PIXE (Particle Induced X-ray Emission) chemical analysis of these ornaments and reference samples from possible sources indicates a mineral origin from the Gava mines, near Barcelona (Spain). This discovery reveals an exchange system of the materials or finished objects on both sides of the Pyrenees mountains during the first half of the 4th millennium BC.
