Ferrosilic Glass Samples from Vicinity of Tallinn

Abstract—Metal and glass samples discovered in 2019 in the vicinity of Tallinn are described. Their structure, composition, and properties are analyzed. In terms of structural and chemical parameters, the samples belong to the same parent body and differ from representatives of known groups of iron meteorites, technogenic ferroalloys, and industrial and natural glasses. Analogs of the material composition of samples are protvanites. The possible cosmic origin of samples is confirmed by surface regmaglypts, fullerenes, other carbon phases, and cohenite.
