Stibnite vein from Dębowina near Bardo (Polish Sudetes)
In the contact zone of the Bardo Structure
and Kłodzko-Złoty Stok Intrusion and
Kłodzko Metamorphic, metasomatic orebearing
quartz-carbonate veins rich in Sb,
Zn, Cu, Ag, Au, Pb are present. In 1771 the
mine ,,Reiche Silber Gluck” within stibnite
vein was founded in Dębowina near Bardo.
Its entrance was discovered again in 2007.
The stibnite vein is mainly build of stibnite
and sphalerite and of quartz and dolomite
rich in Mn. Stibnite crystallizes as columnar
or forming radiate centres and aciculars. Its
crystals reach size to 2 mm. Sphalerite appears
as individual anhedral and polymineralic
grained concentrations reaching size to
2,5 mm. Earlier pyrite and arsenopyrite crystallized
– they occur locally in this deposit.
There were found also in the deposit tetrahedrite
rich in Ag, what wasn't reported earlier
in studies from the mine in Dębowina.
