Manganese deposit. Located within the Obcina Mestecăniș Mts.

One of many stratabound Mn deposits within the East Carpathian Mn-rich belt: a Cambrian/Ordovician (with greenschist facies metamorphism in Silurian) island arc complex. Other deposits include: Arșița (in Iacobeni), Argestrut, Borca, Broșteni, Cosna, Dealul Rusului, Drancani, Oița, Roșu, Sărișor, and Terezia.

In terms of structural geology, these deposits belong to the Central East Carpathian basement nappes. At least some of them, i.e., the ones of the Iacobeni area (Arșița, Tolovanu, Argestrut, Dadu, Oița) are within the Putna Nappe (part of Sub-Bucovinian Nappe). In terms of lithostratigraphy, they belong to Tulgheș Group, that is, Lower Palaeozoic metasedimentary/volcanosedimentary sequence. In a more detailed description they are listed under Harghita Fm. (Tg2), a variegated sequence with Mn-rich metacherts / black quartzites.

Note: this is most likely this quarry (visible in the satellite photoes) and it, approximately, fits to the data interpolated from a large-scale map in Munteanu et al. (2004). The true site might, possibly, be located some 1 km to the SW.

Current exploitation in the very quarry most likely concerns dolomites.
