At the European recent Prehistory variscite was a precious gemmological material that appears in scarce megalithic burials of the Atlantic facade, especially at the Iberian peninsula and West France. Here we describe the main results of the mineralogical and geochemical analysis of a great and diverse group of archaeological and geological variscite and turquoise samples from the Iberian peninsula, especially from the Atlantic facade and the SW of Spain. Samples were analysed last years by the use of different analytical techniques as XRD, WDXRF, ICP-MS-LA and PIXE and stereomicroscopy. The geochemical results, obtained especially by PIXE and ICP-MS-LA techniques, on these archaeological samples were discussed in relation to their possibl...
