| Popis: | The polymetallic Rem{nik ore deposit is situated at the Kobansko area in northern Slovenia. Mineralizationoccurs in the thrust zone of the weakly metamorphosed old Palaeozoic rocks of the Magdalensberg formation, theRem{nik nappe, onto the retrogressed schists of the Austroalpine metamorphic basement. Hydrothermal ore mineralizationand silicification follow slaty cleavage in partly brecciated marmorized dolomite lenses and subordinatelyin metatuffites and phyllites. Its origin is most probably connected to the lively Tertiary magmatism, occurring atthe Pohorje Mountains. Mineral paragenesis of the predominant Pb, Cu and Zn silver bearing sulphide ore is associatedwith numerous secondary minerals. Among them, two rare sulphates with H2O of Cu and Zn occur, foundfor the first time in Slovenia. The green, transparent monoclinic crystals, only some tenth of millimetre in size weredetermined by SEM as ramsbeckite (Cu, Zn)15(SO4)4(OH)22 · 6(H2O). Greenish in colour are also leafy, hexagonal,flowery intergrown crystals, which most probably belong to namuwite (Cu, Zn)4(SO4)(OH)6 · 4(H2O). Its submicroscopicsize and small quantity did not permit reliable determination, yet. |
