wider Carpathian Basin The use of metals in Central Europe developed mostly along the geology of ore deposits. Accordingly, the first ores used were those of the crop zone and the near-surface zone containing oxides-carbonates (cuprite, malachite

conditions 52 for oxidation. These soils are rich in clay minerals that provide easily available nutrients and have a good water retention capacity. Both the red-brown forest soils 53 and the red erubase soils of Tokaj-Hegyalja can be identified as
