Sažetak
Residual soil samples were collected from the small, second order drainage basins at suitable sites above their alluvial plain and base of slope, where alluvium and colluvium are respectively deposited. The distribution of most elements in soil shows a pattern related to geology and/or mineralisation. A major geochemical dichotomy appears on the various maps between soil developed on crystalline and Palaeozoic basement rocks, and those on unfolded cover rocks that are naturally impoverished in most trace elements (except for areas of intense agricultural activity). Palaeocene and Eocene climates caused strong argillic and ferralitic weathering of some basement rocks, with a change in mineralogy, and a modification of vertical and lateral distribution patterns of most major elements. On crystalline bedrock, there is also a systematic difference between the glacial till area encompassing Fennoscandia and Scotland, and the rest of Europe.
