Badania mineralogiczno-petrograficzne właściwości sorpcyjnych węgli drzewnych z cmentarzyska z okresu przedrzymskiego w Babim Dole–Borczu, stan. 2, powiat Kartuzy

The paper presents a putative mechanism of metal sorption by reduced carbon. The sorption of carbon discovered in burials in Babi Dół-Borcz was tested. It was found that the primary material of funeral pyre were pine and oakwood. Chemical examination of charcoal performed using SEM-EDS methods showed presence – amongst other elements – Ca, Mg, Na, Fe, P, Cu etc. Elements were discovered in the tissue of burned wood. Examination of bronze microartefacts discovered in graves confirmed transfer of elements from bronze to charcoal. The described method of charcoal sorption examination may help in location of objects made of certain metals.
