Mikrorelief Raummuster von Böden, äolischen Substraten und Flugstäuben im Hochgebirgskarst der Nördlichen Kalkalpen (Reiteralpe, Berchtesgadener Alpen)
Summary
The current study presents a unique and intensified interdisciplinary geo-ecological study in the Karst of the Northern Calcareous Alps. This is a study focussing on fundamental research. The investigation area in question focusses on the Reiteralpe in the Berchtesgadener Alps, in which a range of research methods, which in their choice and range have not been used to this extent before, are optimal for further adaptation in silmiliar ecological systems and environments.
The results of the study are elementary and moreover profound to the extent that mappings of outcrops have been identified which however have not been identified before by the scientists involved in researching this area over the past hundred years. It was possible to map outcrops of pleistocene loess deposits, holocene aeolian dust deposits and moreover laterite bauxite outcrops of the Gosau Formation thereby resulting in the production of new soil and diverse outcrop maps as well as presenting a new geological stratigraphy for the Berchtesgadener Alps. A combination of soil mapping techniques in combination with using geo-radar technology made it possible to identify a pleistocene glacial cirque and cirque threshhold at 1800m NN on a south slope which likewise had not been identified in the past.
An extenive soil mapping programme taking microtopographical elements of mountain terrains into consideration were extensively investigated mainly focussing on geology, aspect, slope morphology, vegetational cover and elevation. Loess derived soils and (pre-) tertiary soils and holocene soils have been identified in association with mineralgogical anaysis as a result of the mappings. Functions relating to soil depth, grain size distribution of soil horizons, clay formation and spatial distribution in a high altitude mountain karst geo system have been undertaken.The intensely enriced aluminium and iron content of the soils associated with the Gosau Formations were mineralogically analysed and the intensively weathered terra fusca soil formations investigated.
Precipitation sampling during summer months were analysed respective recent holocene aeolian dust deposits in quantity, quality, spatial distribution, silica grain size distribution and mineralogical composition. The results of which were transferred with a focus on the spatial micro topographical and gemorphological distribution. With this data, a correlation was made to organic horizons of polygentetcial soil formations.
