SUMMARY The interpretation of soil susceptibility measurements depends on knowledge of a reference value. This reference value will be influenced by the type of soil. In the present study, data of various soil types, which formed on diverse parent material, are analysed. As the same data set has been used in a soil pollution study, we are able to estimate and exclude the influence of pollution. Susceptibility values of unpolluted soils turn out to significantly depend on the soil type. Chernozem samples yield the highest susceptibility values of the analysed soil types (50–90 × 10−8 m3 kg−1). Cambisol displays intermediate values (20–60 × 10−8 m3 kg−1) and waterlogged soils have the lowest values (5–20 × 10−8 m3 kg−1). The enrichment of topsoil susceptibility (0–20 cm depth) compared to subsoil susceptibility (40–50 cm depth) depends more on the parent material than on the soil type. Given the comparability of soil type and parent material, the values of this study can be used to identify soils with unusual susceptibility values, which may be further analysed in order to pinpoint soil pollution.

This study concentrates on small intrusions along two important faults of the Giudicarie fault system, the Northern Giudicarie and the Meran-Mauls fault, summarised under the term tonalitic lamellae. Magnetic fabric analyses in combination with structural field data indicate dextral strike slip deformation along the NE-SW striking northern part of the Giudicarie fault system, the Meran-Mauls fault, overprinted by younger thrusting. The regional stressfield was oriented approximately NNW-SSE during Tertiary times.
