“…7b presents the late Variscan tectonothermal event, which, within the Dinarides, developed into a rift during Early Permian times. Recorded tectonothermal overprint ranging from 298 Ma to 265 Ma, was synchronous with the formation of widespread siderite-barite-polysulphide deposits (Palinkaš et al 2008;Borojević Šoštarić et al 2009;Strmić Palinkaš et al 2009) and the formation of the Dinaride evaporites. The Permian event could be related to ongoing Alpine rifting similar to that in the Southalpine and Austroalpine basement units of the Alps (e.g.…”

“…During Late Carboniferous-Early Permian times, shallowing of the sedimentary basin evolved into a dry land-phase followed by deposition of fine-to coarse-grained quartz-sandstones and of quartz-conglomerates. The onset of the new sedimentation cycle is interpreted as a possible boundary between the Variscan and post-Variscan tectonic and metallogenic events (Palinkaš et al 2008). Formations of the Paleozoic Banovina-Kordun Unit were interpreted as very low-grade sedimentary sequences (Majer 1964) while the Paleozoic Sana-Una Unit were metamorphosed under low-and very low-grade P-T metamorphic conditions (Podubsky & Pamić 1967;Podubsky 1968).…”

Very low-grade and low-grade metamorphosed basement rocks from distinct inliers of the Africa-derived northwestern Dinarides (Medvednica Mts and Paleozoic Sana-Una Unit, respectively) have been studied with the multigrain step-heating 40 Ar ages from the very low-grade basement exposed at Petrova and Trgovska Gora of the NW Dinarides. Within low-grade metamorphic basement rocks from the Medvednica Mts, we found no Variscan ages. White mica from phyllitic basement rocks of the Medvednica Mts gives predominantly early Alpine ages ranging between 135 and 122 Ma and younger Alpine ages of ~80 Ma. The early Alpine ages of 135 and 122 Ma are interpreted as the date to the onset of ductile nappe stacking predating the formation of Gosau-type collapse basins. The late early Alpine event of ~80 Ma can be traced in the entire Cretaceous-aged orogen of the CircumPannonian Region and is synchronous with subsidence of the Gosau-type basins and opening and closure of the neighbouring Sava-Vardar Zone.

“…Hematite/siderite ore from the Vareš location near Sarajevo are of metasomatic origin deposited in limestones that now form a series of greatly metamorphosed rocks. [29] The metasomatic deposits of siderite had been formed primarily in carbonate rocks in the presence of mineralising solution in line with the reaction: The oxygenation of FeCO3 under hydrogeothermal conditions produced hematite. Hematite at the Vareš location is often associated with smaller amounts of siderite due to an incomplete oxidation of Fe 2+ , as confirmed by present investigation.…”

Natural goethite, hematite and siderite were analysed with 57 Fe Mössbauer, XRD and FT-IR. FE SEM images of samples were also taken. The Mössbauer spectra of limonite (α-FeOOH · nH2O) from Budapest (Hungary), Ljubija (Bosnia and Herzegovina) and Korçё (Albania) showed the same type of spectrum, indicating low crystallinity and broad particle size distribution. All goethite particles from these three locations were one-dimensional (1D), but with different nano/microstructures. A very early precursor of limonite from Budapest and Ljubija locations was assigned to FeS2 (pyrite and/or marcasite) which oxidised upon ventilation (oxygenation) under hydrogeothermal conditions, thus producing FeSO4 and Fe2(SO4)3. In the next step limonite deposits were formed. The similarity between this limonite formation under hydrogeothermal conditions and the chemical precipitation of goethite from FeSO4 or Fe2(SO4)3 solutions at laboratory level was briefly discussed. The deposition of lateritic goethite at the Korçë location is presumed to be due to the chemical weathering (tropical conditions) of ultramafic rocks. Under the same conditions and a proper pH the transformation of goethite to hematite is possible. Alternatively, the oxidation of Fe 2+ in magnetite and its transformation to hematite via maghemite (γ-Fe2O3) as an intermediate could have taken place. The Mössbauer spectrum of siderite from the Ljubija location showed a quadrupole doublet with asymmetric spectral lines. This asymmetry could be assigned to the Goldanskii-Karyagin effect, however, the contribution of the crystallite texture to this asymmetry cannot be excluded. Hematite and a small fraction of siderite at the Vareš location (Bosnia-Herzegovina) are of metasomatic origin deposited in limestone that now form a series of greatly metamorphosed sedimentary rocks. Hematite particles were deposited in the form of laminates (2D).

This paper presents the results of sampling surveys carried out in order to evaluate the environmental impact of the Rude and the Sv. Jakob historical mining sites, NW Croatia. The studied polymetallic ore deposits differ in their mineralogical and geochemical features as well as in the host rock lithology. The Rude Fe-Cu-Pb-Zn-Ba deposit is hosted by Permian siliciclastic sediments. Siderite, haematite, galena, sphalerite, chalcopyrite, pyrite, barite and gypsum are the major ore minerals. The Sv. Jakob Pb-Zn deposit oecurs in the Middle Triassic dolostone. The most abundant ore minerals are galena, sphalerite and pyrite. Although the deposits represent potential sources of numerous toxic metals, no pollution of the drainage streams and associated stream sediments was recorded. The studied mining sites are characterized by high carbonate/sulfide ratios responsible for the alkaline character of the drainage streams (pH=7.3-8.7). Consequently, the mining sites have very low potential for both generation of acid mine drainage and for leaching of heavy metals into the drainage systems. Furthermore, the study revealed that the populated areas (stream waters with decreased redox potential, increased organic matter content, high NO3", NH4* and P04^" concentrations; stream sediments enriched in exchangeable Pb and Zn) and the Sava river alluvium (overflowing streams enriched in Hg) represent a greater environmental threat than the investigated polymetallic ore deposits.
