Complex geoarcheological investigation at the Székelyudvarhely-Kadicsfalva/Cãdiseni site (Romania)

Abstract Environmental historical analyses, including sedimentological, pedological, palynological, archeobotanical and phytolith analyses were carried out on samples derived from the Kadicsfalva/Cãdiseni archeological site. Our aim was to provide paleoenvironmental data to the archeological results in order to reconstruct the former milieu of the Gothic population, and to provide information regarding their environment management. At the end of the Pleistocene loess and alluvial loess developed from the eolian dust that accumulated on the wet surfaces of the Pleistocene sediments. The site provided favorable conditions to host a settlement and supports its long-term colonization owning to the riverside terrace surface location. The comparative analysis of the recent and the Gothic soil horizon proved that the recent soil horizon is over-utilized; its productivity can be maintained only by intensive fertilization and almost every one of its parameters is below the element and nutrient composition of the Gothic soil horizon

A Baláta-tó környezettörténete = The Environmental History of Lake Baláta

Sedimentary basins such as Lake Baláta in Southwestern Hungary provide information about the development of lake-bog systems, the climate change through time and about the environment of the surrounding area. The application of different methods, such as sedimentological, geochemical, macrofossil, pollen and charcoal analysis make it possible to reconstruct the climatic, vegetation and hydrological changes of this protected area for the last 3000 years. Lake Baláta is a sedimentary basin developed in a wind-blown yardang system. Due to its deeper location and the higher groundwater-level the boggy lake functioned as a sediment catchment basin. So by the analysis of samples derive form cores we get closer to the formation, development and the temporal changes of the environment of the lake-bog system
