Abstract:
This bachelor thesis analyzes the soil development in a geological landslide area in the val- ley “Val Müstair”. The valley is located next to the National Park of Switzerland at the most eastern corner of Switzerland. Its climate is continental and dry. The research was carried out within the deposition area of the geological landslide which ranges from 1500 to 2000 meters above sea level. During investigations, carried out in 1998 in this area, soil character- istics were determined which were difficult to integrate into the existing soil classification sys- tem. The fine soil was bleached, nutrient poor and showed a low base saturation. Only spo- radically brown horizons could have been detected. The climate of “Val Müstair” is to dry to allow a podzolization which bleaches the whole soil profile.
With this bachelor thesis further research within the deposition area of the geological landsliede was performed by analyzing 12 soil profiles including the mineralogy of soil and rocks. The results showed the same soil characteristics as they were determined in 1998. Furthermore, the rocks within the geological landslide area were identified as ‘Verrucano’, which consists of Permian sediments. The mineralogical analysis of some of the collected rocks showed, that the rocks mainly consist of quartz and muscovite. The determined soil characteristic could be explained do to the lack of iron, magnesium and calcium within the mineralogy of the rocks. The sporadically detected brown horizons could be associated with the presence of local accumulations of ferruginous minerals in some rocks of the ‘Verrucano’. These minerals could not be detected with the applied mineralogical analysis, but it is as- sumed to be biotite or clinochlore (chlorite). The soil within the deposition area of the geolog- ical landslide can conclusively be described as raw soil with a beginning brunification in parts where ferruginous minerals are present in the rocks. Some areas which were not dominated by the ‘Verrucano’, showed a more differentiated soil development.
