The disseminated copper mineralization is related to the Permian postvolcanic hydrothermal activity of basaltic volcanism. The association of minerals reflects composition of wall-rocks, as confirmed by the presence of Ni-Co minerals (siegenite, gersdorffite and carollite). The vein copper mineralization is associated with faults formed during the Alpine overthrust of the Hronicum Unit. These structures allowed the circulation of the hydrothermal fluids. More data are needed to explain the origin of these fluids. Metallic elements might be mobilized from disseminated preconcentrations, and subsequently transported and deposited into the structurally favourable milieu. Low temperature chalcopyrite, digenite, covellite, idaite, malachite, azurite, iron hydroxides, jarosite and gypsum represent supergene association of minerals. Acknowledgement We thank ¼.
