The paper presents new data on the weathering zone in Miedzianka, Holy Cross Mountains (Poland), including macroscopic, microscopic and chemical investigation, using scanning electron microscope (SEM) with energy dispersive spectrum (EDS). The deposit contains sulphide mineralization (e.g. chalcopiryte, chalcocite), and carbonates with hydroxyl (malachite and azurite) in the weathering zone. Additionally, arsenic – bearing sulphosalts of the tennantite – tetrahedrite group and Ba-sulphate were found. Moreover, cracks are observed on a macro- and micro-scale, filled with new minerals that formed during the weathering.

Wody strefy aeracji na hałdzie kopalni Schwarz Adler w Miedziance charakteryzują się bardzo silną zmiennością składu chemicznego oraz cech fizycznych i chemicznych. Ich chemizm znacznie odbiega od typowych wód strefy saturacji. Na badanej hałdzie identyfikowano różne fazy mineralne podczas okresowych, sezonowych sesji terenowych. Wyniki obserwacji zmienności warunków hydrogeochemicznych zostały potwierdzone przez modelowanie geochemiczne z użyciem programu PHREEQC.

Groundwater from aeration zone on dump of Schwarz Adler mine in Miedzianka has a very strong variation of chemical composition and physical and chemical characteristics. Their chemistry is far from typical waters of saturation zone. Different sets of mineral phases were identified during the fields sessions on the examined dump. These observations indicate variability of hydrogeochemical conditions and processes. The results of investigations are confirmed by geochemical modeling using the PHREEQC code.

Dla turystów, którzy interesują się górnictwem, geologią i archeologią, jednym z ciekawszych regionów Polski są Góry Świętokrzyskie. W przeszłości intensywną, podziemną eksploatację kruszców prowadzono m.in. w oddalonej o ok. 10 km od Chęcin górze Miedzianka. Obecnie na jej stokach można znaleźć ślady dawnego górnictwa kruszcowego. Niektóre z nich, w postaci sztolni i korytarzy, po odpowiednim zagospodarowaniu i przystosowaniu do ruchu turystycznego mogą stanowić ciekawą propozycję dla osób odwiedzających województwo świętokrzyskie.

“Miedzianka Mountain” reserve in Chęciny municipality includes, among others, a hill having the same name, where copper ore and silver was extracted in the past on an industrial scale. As a result, a number of excavations connected with natural caves were formed and they have never been made available to visitors before. The types of ore concentrations in the deposit were mined at various stages of its exploitation, dating back to the second half of the 15th century. Two important mining drifts are described in the article: “Zofia” and “Teresa”, the qualities of which justify the purpose of making them available for tourists. It has been emphasized that adaptation of the caves and underground post-mining excavations for visitors and tourists is the right way to protect them effectively and to use them for touristic purposes.

The historical deposit of polymetallic ore in Miedzianka-Ciechanowice is located in the Rudawy Janowickie Mts. This deposit includes lens-forming contact-metasomatic ores and hydrothermal veins related to the Karkonosze granite. The ore assemblages are abundant in Cu, and more rarely in Pb, Ag, As, Fe, and others elements, were mined in Miedzianka-Ciechanowice from the early Middle Ages to the mid 20th century. This paper presents descriptions the selected objects of mining and smelting activity in the Miedzianka-Ciechanowice area. Old dumps, adits, shafts and ruins of copper smelter are a unique assemble of relicts related to the development of the local mining. The authors propose to create a geotourist route in this area.

The Miedzianka mining district has been known for ages as a site of polymetallic ore deposits with copper and, later, uranium as the main commodities. Although recently uneconomic and hardly accessible, the Miedzianka ores attract Earth scientists due to the interesting and still controversial details of their ore structure, mineralogy and origin. Our examination of the ore mineralization from the Miedzianka district was based exclusively on samples collected from old mining dumps located in the vicinity of Miedzianka and Ciechanowice, and on samples from the only available outcrop in Przybkowice. In samples from the Miedzianka field, chalcopyrite, pyrite, galena, bornite, chalcocite, digenite, arsenopyrite, magnetite, sphalerite, tetrahedrite-tennantite, bornite, hematite, martite, pyrrhotite, ilmenite, cassiterite and covellite are hosted in quartz-mica schists and in coarse-grained quartz with chlorite. In the Ciechanowice field, the ore mineralization occurs mainly in strongly chloritized amphibolites occasionally intergrown with quartz and, rarely, with carbonates. Other host-rocks are quartz-chlorite schist and quartzites. Microscopic examination revealed the presence of chalcopyrite, pyrite, sphalerite, galena, tetrahedrite-tennantite, bismuthinite, native Bi, arsenopyrite, löllingite, cassiterite, cobaltite, gersdorffite, chalcocite, cassiterite, bornite, covellite, marcasite and pyrrhotite. Moreover, mawsonite and wittichenite were identified for the first time in the district. In barite veins cross-cutting the greenstones and greenschists in Przybkowice, we found previously-known chalcopyrite, chalcocite and galena. The composition of the hydrothermal fluids is suggested to evolved through a series of consecutive systems characterized, in turn, by Ti-Fe-Sn, Fe- As-S, Fe-Co-As-S, Cu-Zn-S and, finally, Cu-Pb-Sb-As-Bi compositions.
