Abstract

Cilj ovog rada bio je kreirati geokemijski prikaz prostorne distribucije elemenata rudarskog područja Rude, smještenog u zapadnom dijelu Zagrebačke županije. Geološka podloga obuhvaća formacije od paleozoika do kvartara, s bogatom mineralizacijom, uključujući žile siderita, polisulfida, barita i kvarca. Tijekom terenskog rada prikupljen je 21 uzoraka tla iz mreže u razmacima od 100x100 metara, s dubine od 25 cm. Na uzorcima tla određen pH, boja tla i elementarni sastav pomoću rendgenske fluorescencije (XRF). Podaci su statistički obrađeni, koristeći srednje vrijednosti, standardne devijacije i korelacijsku analizu. Pomoću GIS QGIS alata, kreirane su geokemijske karte za prostornu analizu, a interpolacija je izvedena metodom inverzne udaljenosti. Rezultati pokazuju varijabilne pH vrijednosti, s neutralnim tlom u području Ruda (medijan 7,06) i kiselijim tlom oko Classenbrucha (medijan 5,55). Geokemijske karte otkrile su visoke koncentracije Fe, Cu, Ba, Pb, Zn, Hg i As u blizini rudarskih i naseljenih područja.

Abstract (english)

The aim of this thesis was to show a spatial distribution of elements in the soil surrounding the Rude mining area, located in the western part of Zagreb County. The geological foundation includes formations from the Paleozoic to the Quaternary, with rich mineralization, including veins of siderite, polysulfides, barite, and quartz. During fieldwork, 21 soil samples were collected from a grid with 100x100 meter spacing, at a depth of 25 cm. The samples were analyzed for pH, soil color, and elemental composition using X-ray fluorescence (XRF). The data were statistically processed, utilizing mean values, standard deviations, and correlation analysis. Geochemical maps were created using GIS tools (QGIS) for spatial analysis, with interpolation performed using the inverse distance method. The results show variable pH values, with neutral soil in the Rude area (median 7.06) and more acidic soil around Classenbruch (median 5.55). Geochemical maps revealed high concentrations of Fe, Cu, Ba, Pb, Zn, Hg and As near the mining and residential areas.
