VIIVI b.C) to assign the origin of these materials using spectroscopic analysis. For this purpose, a total of 30 samples of minerals defined as talc have been analyzed, from different geological outcrops in the north of the peninsula and the archaeological site.Based on the results obtained, the origin of the talcs used in La Ercina seems to respond to a regional supply (<60 km), bothtowards the NE (outcrop of Pico de las tres Provincas) and the NW (Talc mines of Puebla de Lillo). Finally, all the analyzes carriedout have allowed the creation of a specific spectrometry database of these minerals that can be used for the identification of otherpieces in museums, since it is a non-destructive technique.
