    Opis:
    The study of new occurrences of Pb-Zn mineralization in the Lower Triassic rocks in the NE part of the Silesian-Cracow region was performer. Pb-Zn ore minerals occur in sandstones, gravels and oolitic dolomites and are represented by galena, sphalerite, pyrite, marcasite and an admixture ofchalcopyrite. Vein minerals: barite with celestite, calcite and partly anglesite were also found.

    Opis:
    The depletion of Zn-Pb ores in developed mining areas and the increase in metal prices have resulted in the need to search for new deposits which have not been exploited yet. A project of drilling new exploratory boreholes should be preceded by an interpretation of archival geological data. To obtain the most valuable information on the geological structure leading to its plausible interpretation, it seems to be purposeful and advisable to apply some geophysical methods that are reasonably cheap in comparison with others. The method of electrical resistivity tomography, which in this research uses two of many measurement protocols such as Schlumberger array and dipole-dipole array, is particularly useful. Computer interpretation of geophysical results allows a high resolution 2D and 3D geoelectrical model of rock mass to be created. The study was carried out using the multi-electrode Lund Imaging System manufactured by ABEM, Sweden. In order to evaluate the practical application of this method, Zawiercie Zn-Pb ore deposits were chosen as the area used in previous scientific research. Taking into account mineralization in its economic aspect, the deposits occur at relatively shallow depths of 50-120 m. In the investigated region, the Triassic carbonate formation overlays the Devonian rocks. The Keuper low-resistance clay, occurring on the surface, provides a very good electrical contact between an electrode and the soil. This is why there are favourable measurement conditions in this area. The boundaries between the Keuper, Devonian and Triassic formations are clearly noticeable in the resistivity cross-sections obtained. On the basis of the ERT results, it is possible to locate faulting zones as well as karst systems. One of the profiles clearly shows the occurrence of a low-resistance anomaly correlated with Zn-Pb mineralization, which was confirmed by borehole surveys. However, this early stage of the research with the use of the ERT method cannot unequivocally identify the ore body, particularly as it was conditioned by the limited depth of prospecting.

    Opis:
    The paper presents changes in groundwater chemistry of Triassic aquifer after zinc-lead mine flooding. Last stage of liquidation Zn-Pb “Trzebionka” mine has been started in July of 2010. Long lasting drainage caused oxidation of the sulphide minerals in hosted rocks of Zn-Pb deposits. Flushing of the extended unsaturated zone led to dissolving of weathering products. Those complicated processes caused significant increase in sulphates concentrations Prediction of consequence of mine flooding for water chemical composition is possible due to long term observation of the water quality in the “Trzebionka” zinc-lead ore. Currently water quality of Triassic aquifer is deteriorate.

    Opis:
    The Pomorzany mine, currently the only one Zn-Pb mine in Poland and one of the largest underground mines of this type worldwide (output 2.5 Mt/y) exceeded 40 years of operation on the MV-type deposit. In 1960, the first geological report on its resources based on drillings was issued. Data from this long period were used to analyse the resource management and evolution of reserve tonnage and quality due to changes in the economic and technical viability as well as to qualify different categories of mine reserves and losses due to the ongoing operation. The mine project was based on geological resource of 97.6 Mt ore averaging 4.12% Zn and 1.42% Pb. Resources extracted with documented low losses and those remaining in situ amount to 92.7 Mt averaging 4.18% Zn and 1.27% Pb. These figures indicate the high accuracy of the exploration results and cost-effective management of resources. The observed trend of ore reserve increase over the last decade gives hope of delimiting at least 3 Mt over the next three years. The mine, which was planned for a 30-year life cycle, has sufficient reserves until 2016, and under favourable market conditions, may extend its life up to 2018.

    Opis:
    Significant traffic congestion can lead to contamination of the soil and water environment within the range of its impact, i.a. with mercury, lead, cadmium, chromium and zinc. As a consequence of contamination of the subsurface soil layers, migration of metal ions into groundwater is possible, consequently leading to contamination of local aquifers. In 2015-2016 a soil test was conducted at a depth of 0.4-0.6 m below surface level in the vicinity of about a dozen kilometers from the southern ring road of Kraków. The total contents of mercury, lead, cadmium, chromium and zinc were measured in the collected samples (mainly medium and fine sands) and a leaching test was conducted using the classical batch test 1:10. The mercury content in the soil samples ranged between 0.02 and 0.06 mg/kg, cadmium 0.1 to 0.7 mg/kg, chromium 0.3 to as much as 116 mg/kg, lead from 3.7 to 26.6 mg/kg and zinc from 17 to 102 mg/kg. The conducted leaching tests have shown that in all samples the release of metal ions into the solution may be observed. The solubility of the compounds of the analyzed metals ranges from a fraction of a percentage point (0.01% for zinc) up to a few and even, as in the case of mercury, over a dozen percent (approx. 15.7%) of the total metal content accumulated in the soil.

    Opis:
    In the shadow of discoveries of large deposits of mineral resources in Poland after World War II, intensive exploration works were carried out, but the results of this research did not bring such spectacular effects. Exploration of Zn-Pb deposits conducted in the vicinity of historic deposits of Tarnowskie Góry and Bytom led to documentation of the Zawiercie, Goluchowice and Marciszów deposits. With some successes, exploration works of metal ore deposits in Paleozoic igneous and metamorphic rocks of the NE margin of the Upper Silesian Coal Basin were carried out. In this area, the Myszków Mo-W-Cu mineral deposit was confirmed, representing the porphyry copper genetic type. Moreover, in the area of Mrzyglód, the promising mineralization zone was found, requiring further geological research. The exploration of uranium and rare earth element ores did not lead to documentation of the deposits, nevertheless they made it possible to recognize all geological structures in Poland in terms of the possibility of occurrence of ore deposit occurrence of these metals. The prospecting works for these goals was carried out with a relatively small scale and were limited of the Sudetes, where exploitation took place on a fairly large scale in the past (Zloty Stok, Radzimowice, Klecza-Radomice, Wądroże Wielkie). The gold concentration occurring in the Zechstein Kupferschiefer formation and the porphyry copper mineralisation in NE margin of the Upper Silesian Coal Basin were also studied. The PGI participated in the exploration of mineral resources in marine areas, where besides the hydrocarbon exploration in the Polish economic zone, research on the Baltic polymetallic nodules was carried out, and within the INTEROCEANMETAL consortium the raw material potential of the Clarion-Clipperton Zone in the Pacific was studied.

    Opis:
    The paper presents results of studies on storm-generated surface runoff, a phenomenon belonging to the least known factors responsible for migration of pollutants to water environment. The results of determinations of pH, conductivity as well as content of Ca, Zn, Cd, and Pb are found to be useful as the main indicators of pollution spread by waters running from dam slopes of pond in which tailings from flotation of Zn-Pb ore are disposed. Rain water leaches fine fractions of carbonate-sulfate wastes (represented mainly by dolomite, 73%, and Fe sulfides – marcasite, up to 20%) which leads to change in character of surface runoff water to that of SO4-Ca hydro-chemical type. Among the leached metals significantly important for the environment are Zn, Cd and Pb whose concentrations exceed threshold values for surface and/or groundwater of IV quality class. Acceptable concentrations in waste waters are frequently exceeded by sulfates and incidentally by zinc. Variability of the analyzed concentration indices from the years 2008 and 2009 indicates influence of weather conditions on chemical composition of surface runoff water from slopes of tailings pond of flotation plant of MVT ores.
