Occurrences of manganese linked to volcanism, stratiform. Geology: lenses and bands of pyrolusite and psilomelane, oriented N55º W and 80º NE, sub-concordant with the host rocks; at depth, rhodochrosite and rhodonite appear. Host rocks: jasper, quartzites, tuffs, schists. Contact zone of the volcano-sedimentary complex with phyllite-quartzitic formation, Mértola-Albernoa sub-sector.
