Finding the origin of Polish Moldavites

Moldavite is a rare natural glass which was possibly formed as a result of the impact of a meteorite on Central Europe several millions of years ago leaving behind several small areas with this material (sub-strewn fields). The study of moldavites provides valuable information on the paleogeography and geological history of the area of impact.
A research group was interested in studying the origin of moldavites found in Poland. In particular, they wanted to find out if the moldavites were transported from the Lusatian sub-strewn field or if they were deposited directly at the time of impact forming a new separate sub-strewn field.
The TESCAN SEM VEGA3 XM was used to image the surface and polished thin sections of the moldavite specimens.
