Abstract.

 290 Million years old petrifactions from the Lower Permian Rotliegend of Chemnitz were examined by analytical X-ray microscopy to determine their chemical composition. Mappings show the inhomogeneous distribution of the involved elements, which may reflect the former plant anatomy, as well as some contemporaneous processes of permineralization (with silica and fluorite) and agate-formation. Most prominent advantages of the analytical X-ray microscopy are the low preparation expense of the museum samples, the analysis scanning range and the X-ray spot diameter suitable with the dimension of the fossil plants.
