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.
