Geologically, Anglesite is a secondary mineral formed by the alteration of Galena within the oxidation zone of the deposit. In the Linares-La Carolina mining district, hydrothermal lead veins hosted by Paleozoic rocks gave rise to some of the finest associations of secondary lead minerals found in Spain.

Santa Flora Mine belongs to the Sierra Norte mining district of Seville, within the Ossa-Morena Zone, a Paleozoic geological domain affected by the Variscan orogeny. Mineralization is mainly hydrothermal vein-type, hosted in fractures and shear zones developed in Hercynian metamorphic and igneous rocks.
The veins are dominated by metallic sulfides, mainly of lead, zinc, and copper, with gangue minerals such as Quartz, Calcite, and Baryte. This mineralization style is typical of Variscan hydrothermal systems in the area, historically worked through small to medium-scale mining operations controlled by regional structures.
