The Świślina river valley structure at the Doły Biskupie site (Holy Cross Mountains, central Poland) – preliminary results

Abstract

The structure of the Świślina river valley (Holy Cross Mountains, central Poland) was the subject of research dating back to the 1950s. Returning to this place after the years in 2014 and 2020 made it possible to use new methods in the analysis of sediments building studied area. For this purpose, climbing equipment was used to get to hard-to-reach places. Samples were taken for grain size and geochemical analysis. The results of analyzes based on magnetic separation of microscopic slags were also taken into account. These results allowed to obtain new data about the structure of this part of the valley. Changes in sedimentation associated with natural processes as well as with the intensification of human activity in last centuries (metallurgical activity, flash floods) were captured
