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.
