    Opis:
    Preliminary sulphur isotope data are presented for selected ore deposits and occurrences in the Karkonosze-Izera Massif, namely, polymetallic mineralization sites at Budniki, Ciechanowice, Izerskie Garby and Sowia Dolina, and the pyrite deposit at Wieściszowice. The data reveal two populations of δ34S values: from 2.74 to 3.95‰ (pyrrhotites and pyrites in Sowia Dolina, and some pyrites in Wieściszowice) and from 0.79 to 1.8‰ (pyrites in Budniki, Ciechanowice and Izerskie Garby, and some pyrites from Wieściszowice). All of the data are indicative of endogenic sulphur typical of hydrothermal mineralization despite the genetic differences between the sites.

    statistical evaluation
    Suoi Thau-Sang Than region
    Vietnam
    Opis:
    In Northeast Vietnam, Suoi Thau-Sang Than is considered as a high potential area of polymetallic deposits. 1,720 geochemical samples were used to investigate polymetallic mineralization; thereby polymetallic ore occurrences in this study region were discovered and the statistical and multivariate analysis helps to define geochemical anomalies in some northeastern regions, namely Suoi Thau, Sang Than, and Ban Kep. The statistical method and cluster analysis of geochemical data indicate that the Cu, Pb, and Zn elements are good indicators, and most of them comply with the lognormal or gamma distribution. Based on the third-order threshold, the geochemical anomalies of the content of the Cu, Pb, and Zn elements reflect the concentration of copper forming ore bodies in the mineralized zone, and clearly show the concentration in three distinct zones. The trend surface analysis which was employed to determine spatial variations and relationships among these good indicator elements and anomalous areas revealed relative changes in the content of the indicator elements, and they can be considered as regular. Moreover, the goodness of fit obtained trend functions of Pb and Zn, and Cu elements is a third-degree trend surface model. These results indicate that the models can be useful in studying geochemical anomalies and analyzing the tendency of the concentration of indicator elements in the Suoi Thau-Sang Than region. Additionally, it is suggested that the statistical analysis shows a remarkable potential to use the bottom river sediments in the region to investigate polymetallic mineralization. Moreover, geochemical data can help to evaluate geochemical anomalies of the pathfinder elements and potential mineral mapping of the Suoi Thau-Sang Than region in Northeast Vietnam.

    Opis:
    Chlorite-mica-quartz schist in the Gierczyn-Przecznica area in SW Poland contains polymetallic ores which were the source of tin and cobalt in the past. This mineralogical study revealed the presence of silver-bearing minerals including members of the tetrahedrite (Ag <3 apfu) and freibergite series (3 < Ag < 8 apfu), galena (0.26–1.48 wt.% Ag), and a phase with the chemical composition of Te-rich canfieldite Ag8Sn(S,Te)6. In Przecznica Sn-sulphides are represented by stannite while cobaltite is the most abundant host for cobalt, followed by Co-bearing arsenopyrite. Glaucodot, ullmannite and members of the löllingite-rammelsbergite solid-solution series (Fe,Ni,Co)As2 also contain cobalt but are scarce in the samples. An exposure in the “Psi Grzbiet” area is characterized by the presence of Ag, Ni, Sb and Te minerals accompanied by very small amounts of As-bearing phases (represented by arsenopyrite) while the mineralogical composition in the Przecznica area is characterized by an abundance of As phases and a lack of Sb minerals. Sulphur isotopes of sulphides from Przecznica are heavier than in most deposits related to the Karkonosze Granite intrusion, while their Pb isotope signature in galena suggests an Early Paleozoic pre-Variscan affinity rather than a Variscan one.

    Pieniny Mts.
    Opis:
    Geochemical prospecting was conducted in three areas of the Pieniny Mountains: Wżar, Jarmuta and Bryjarka regions. Rock samples were collected in the regular grid of 100 x 100 m. A total number of 786 samples were collected from these areas (449 samples near Wżar Mt., 256 samples from Jarmuta, and 81 samples from Bryjarka). Forty-one samples were taken from the Wżar and Jarmuta quarries. Thirty samples of aqueous sediments and pan concentrates were collected from streams of the study areas. The geochemical studies show elevated concentrations of Pb, As, Bi, Cd, Zn, Sn, Tl and K (Rb) in the south-western part of the Wżar Mt., and elevated concentrations of Pb, Bi, Cd, Cu, Ni, Sb, Zn, Fe, Hg and Mn in the vicinity of Jarmuta. Stream sediment samples from the Bryjarka area contain 0.358 and 0.291 ppm Hg (Ścigocki stream) and 0.037ppm Au (Szczawny stream). These anomalies suggest the presence of weak ore mineralization associated with hydrothermal processes due to andesite magmatism. Based on analytical data, it may be concluded that investigated areas of the Wżar, Bryjarka and Jarmuta Mt. are not prospective for ore deposits. The only zone that requires detailed studies is the northern part of Jarmuta, where increased concentrations of Ag within the limits of 7.0-88.0 ppm were found in slope-wash clays in 12 neighbouring samples. The studies of pan concentrates show the presence of detrital gold in the Szczawny stream (1 grain) and the Grajcarek stream (3 grains in 2 samples).

    Opis:
    Borehole Cianowice-2 was drilled several kilometers to the NW of Kraków. Under the Jurassic deposits, at a depth of 265.3-600.0 m, Ediacaran clastic sediments with polymetallic mineralization represented by a group of dozen ore minerals, mainly sulphides and sulphosalts were found. This is low-temperature, hydrothermal mineralization, which along with local metasomatic transformations indicates that the Ediacaran rocks are probably related to the nearby intrusion of acid igneous rocks. In order to locate this hypothetical intrusion, detailed gravimetric and magnetic tests were performed. As a result, a negative gravimetric anomaly was discovered with minima in the region of Maszyce and Pr¹dnik Ojcowski. An optimal borehole location for a further exploration was proposed near the Podmaszyckie hamlet at a depth of about 1000 m.

    polymetallic mineralization
    Opis:
    In the northern part of the Upper Silesian Block, there is a latitudinal structure, several kilometres wide, stretching from Zawiercie through Siewierz towards Tworóg, where Devonian carbonate formations occur directly under the Triassic overburden. This tectonically controlled elevated structure, redefined in this paper as the Brudzowice (Siewierz) elevation, is the effect of Variscan restructuring of the area, which was accompanied by magmatism carrying polymetallic mineralization, and by intense erosion reaching the Lower Devonian formations. The Bibiela PIG-1 borehole, drilled in 2016, revealed the presence of Ordovician and Ediacaran clastics under the Devonian, in which metasomatic changes and ore mineralization located within the range of low-temperature hydrothermal effects associated with an acid magmatic intrusion were observed. A complex ore association with Cu, Fe, Zn, Pb, and Ni and As minerals have been found. The presence of chalcopyrite extends the list of documented manifestations of copper mineralization in the Upper Silesian Block, so far observed in the late Paleozoic and Lower Triassic formations, thus indicating the prospect for further exploration in this area.
