Abstract
Samples of metal and glass found in 2019 in the vicinity of Tallinn are described. The structure, composition and properties of the samples were analyzed. According to their structural and chemical characteristics, the samples belong to the same parent body and differ from representatives of known groups of iron meteorites, artificial ferroalloys, technical and natural glasses. The glass matrix of the samples contains “folds” and “stripes”. Metallic inclusions in glass predominantly consist of alpha iron with an admixture of troilite. Carbon inclusions predominate in the metal matrix of the samples. Analogues of the material composition of the samples are protvanites. The possible cosmic origin of the samples is confirmed by surface regmaglypts, fullerenes, other carbon phases and cohenite.
