Scanning of sediment cores from Lake Byszyno and Lake Rybackie

2015.07.14 -

The sediment cores sampled from Lake Byszyno and Lake Rybackie were analysed at the University of Bremen with an XRF core scanner for the content of individual chemical elements present in the sediments.

The method of X-ray fluorescence (XRF) has many advantages and is widely used for studying lake sediment cores. The method is non-destructive which means that samples are tested without physical contact with the measuring detector and thus are not altered by the analysis. The sediment core can be examined without sub-sampling and spatial resolution of analysis is very high (less than 1 mm), which is impossible with traditional sampling methods and analysis of individual samples.

The XRF scanning of the sediments from Lake Byszyno and Lake Rybackie will help in determining the rate and character of environmental change occurring during the Migration Period in the catchment of the investigated lakes.
