Scientists have conducted a new study of shale rings found in North-Eastern Europe.
Previously, the archaeologists who discovered these fragments of shale rings assumed that the rings broke into pieces naturally after burial.
To find proof it happeneddeliberately, the researchers matched pieces of jewelry from slate rings, analyzed their geochemical composition and looked for traces of use. So, it turned out that some of the halves were processed more carefully than others. Perhaps it indicates personal preference when using them.
The statement says that a large numbersuch fragments have been found throughout northeastern Europe, possibly indicating a large exchange network. Some of these "decorations of friendship" originate from Lake Onega in Russia and were transported to Finland. To find out, the scientists used X-ray fluorescence analysis. He helped determine the elemental composition of nearly 60 shale fragments.
