Resumen
The Cameros Basin has a great mining tradition as evidenced by different documents and mining vestiges, however there are hardly any studies of mineralization. The stratigraphy of the basin consists in sequences of conglomerates, sands, muds and lacustrine limestone at the top. These sequences have been affected by a very low to low metamorphism during the Middle-Upper Cretaceous and no magmatic signs have been observed (Mas et al., 2002). The mining vestige is located in the vicinity of Gallinero de Cameros (La Rioja), and it consists of a collapsed pithead (Fig. 1A), situated in a silicified conglomerates and quartzites level coated by green and blue patinas, and a dump composed of several centimetric blocks of these rocks. The history of this mining evidence is uncertain because there are no documents in the Regional Historic Archive of La Rioja. The aim of this work was the preliminary study of the mineralization of this mine
