Paleontology and Stratigraphy of Fossils

Amber samples of different provenance have been investigated by electron impact and fieldionisation mass-spectrometry. Whereas electron-impact mass-spectra are not specific enough, fieldionisation spectra enable one to identify amber from Baltic-, Sicilian-, Canadian- and Libanese areas. Fe, Na, B, Ca, Mn, Al, Ti, Cu, Cr, V and Si could be determined by emission spectroscopy. Baltic amber shows a smaller trace-element content than all other samples investigated. Canadian amber shows a higher manganese content.
