Resumen
The Candelaria mine is located in the Valoria river valley in Gallinero de Cameros (La Rioja), WGS84 30T 531550 E 4668600N, within the Cameros Basin. This was formed during the second extensional stage of the Iberian Mesozoic rift (Upper Jurassic-Lower Cretaceous) and, later, in the Alpine Orogeny, underwent a tectonic inversion, constituting the current positive relief (Salas et al., 2001). The host rocks of the mineralization are quartzitic conglomerates and sandstones of fluvial environments laterally related to shallow carbonate lakes belonging to the Tera Group (Purbeck facies). This basin has a great mining tradition as evidenced by different documents; however, there are hardly any studies of its mineralizations. The Candelaria mine was exploited in 1889 by Don Braulio de Pablo after confirmation by the Civil Government of the Province of Logroño. In the Municipal Archives of Gallinero de Cameros, it is described as a "argentiferous lead” mine. Nowadays, only a small gallery and a dump of small dimensions remain in the area. The aim of this work was to perform a preliminary chemical-mineralogical study of the Candelaria mine mineralization.
