The Mn orebody occur as lenses and is hosted in CVS’s jasper and metasediments (XJM). Primary paragenesis consists of rhodonite and rhodochrosite (SRM), with a predominance of the latter. These are subsequently affected by regional metamorphism, being recrystallized and enriched in Mn – partially replacing them with both spessartine and braunite (MMM). This is followed by the replacement of the braunite masses by at least two Mn (hydr)oxides minerals, most probably associated to supergene enrichment, including pyrolusite (MNS). Finally, intense albitization affects all previous geological domains, occasionally leaving relics and being accompanied by rare late quartz veins, in one of which grains of ardennite are observed.
Despite the longevity of the mine and its mining operations (from its discovery until 1976, albeit with several long interruptions), there is little geological information available, as the records are old and quite disorganized, many of them lacking reference to authors and/or year of publication.
