Sažetak
Indium is a very rare element, which is usually not reported in geochemical data sets. It is classified as a critical metal, with important applications in the electronics industry, especially in the production of solar panels and liquid-crystal displays (LCDs). Over 4000 samples of agricultural and grazing land soil have been collected for the "Geochemical Mapping of Agricultural and Grazing Land Soil of Europe" (GEMAS) project, carried out by the EuroGeoSurveys Geochemistry Expert Group. Indium concentrations in soil have been analysed using aqua regia extraction followed ba ICP-MS. Median values of In for both land use types are nearly identical, 0.0176 mg/kg for agricultural soil and 0.0177 mg/kg for grazing land soil. The spatial distribution patterns of In in European soil are mailny controlled by geology and the presence of Zn and Sn mineralisation. The preference of In to accumulate in the fine-grained fraction of soil with hign clay content dominates the majoy anomaly patterns on the geochemical maps. In the Mediterranean region, secondary In enrichment is visible in karst areas. A notable feature of the In spatial distribution is the large difference between northern and southern Europe, with median values of 0.012 and 0.021 mg In/kg, respectively, suggesting that, in addition to lithology, weathering and climate are important factors influencing in soil enrichment over time.
