Abstract (in english)
   Contents of major elements determined by EPMA for Cheb, South-Bohemian and Moravian moldavites overlap. The trends observed in the Harker plots seem to differentiate several partial subgroups, some of them characteristic for Cheb tektites only. These results are also substantiated by cluster analysis. CI-normalized REE patterns for the Cheb tektites compare well with those for other moldavites. Discovery of a new moldavite strewn subfield around Cheb substantiates the theory that moldavites were ejected from the Ries structure in a fan-shaped jet. The chemistry of the Cheb moldavites indicates precursor material heterogeneity.
