Soil formation and weathering in a permafrost environment of the Swiss Alps: a multi-parameter and non-steady-state approach
Spatially discontinuous permafrost conditions frequently occur in the European Alps. How soils under such conditionshave evolved and how they may react to climate warming is largely unknown. This study focuses on the comparison of nearby soilsthat are characterised by the presence or absence of perm...

Spatially discontinuous permafrost conditions frequently occur in the European Alps. How soils under such conditionshave evolved and how they may react to climate warming is largely unknown. This study focuses on the comparison of nearby soilsthat are characterised by the presence or absence of permafrost (active-layer thickness: 2–3 m) in the alpine (tundra) and subalpine(forest) range of the Eastern Swiss Alps using a multimethod (geochemical and mineralogical) approach. Moreover, a new non-steady-state concept was applied to determine rates of chemical weathering, soil erosion, soil formation, soil denudation, and soilproduction. Long-term chemical weathering rates, soil formation and erosion rates were assessed by using immobile elements,fine-earth stocks and meteoric10Be. In addition, the weathering index (K + Ca)/Ti, the amount of Fe- and Al-oxyhydroxides and clayminerals characteristics were considered. All methods indicated that the differences between permafrost-affected and non-permafrost-affected soils were small. Furthermore, the soils did not uniformly differ in their weathering behaviour. A tendencytowards less intense weathering in soils that were affected by permafrost was noted: at most sites, weathering rates, the proportionof oxyhydroxides and the weathering stage of clay minerals were lower in permafrost soils.
