Nowe znaleziska mołdawitów w Polsce

Moldavites represent tektites derived from the Ries impact structure ca. 14 Ma. in southern Germany. Approximately 36 moldavite specimens from Poland have been reported since 2012. Characteristic moldavites features, especially bubbles and inclusions of lechatelierite, are reported in all found moldavites. Almost all of them are genetically connected with the Miocene Gozdnica Formation. Only two have been found in Pleistocene sediments, which are part of the Nysa Łużyca river terrace sediments. In 2020, four more moldavites have been collected from Poland. One specimen was found in Gozdnica village, and the other three in Jaroszów village, which is located ~10 km east of Strzegom. Numerous moldavites are generally found in Poland, widely distributed based on the distance from the Ries crater, exceeding 500 km, experimentally determined based on the transport mechanism. However, the lack of the autochthonous tektites indicates that tektites investigated up to now, had to be redeposited in a fluvial environment, probably from the Lusatian area as well as from the Czech Republic.
