Polska - Opis:
- The first Polish moldavites were discovered in 2012. This paper is a summary of the distribution and inventory of these Polish tektites. Up to the present, 28 moldavites have been described from seven different sandpits. These moldavites were deposited in the upper Miocene fluvial deposits of the Gozdnica Formation, as well as in the Pleistocene river terraces. Apart from a typical bottle green colour, moldavites also have other diagnostics features for this class of tektites, such as the presence of bubbles, inclusions oflechatelierite, as well as the same, homogeneous chemical composition. Fluvial redeposition was interpreted as the main process which determined moldavite distribution. Despite the most recent find of one moldavite specimen in Bielawy, all of these specimens indicate both Lusatian as well as sub-strewn Czech fields as their supply area.
