- Аннотация: Antarctica is considered the best place to assess the amount and composition of cosmic matter arriving at Earth. The unique conditions of Antarctica make it possible to collect samples and determine the type and amount of cosmic and other particles that got into the sample during the sampling period. The result of dust collection depends on the conditions and time of collection, including the trap's design. Dust collection using a trap made of NdFeB magnets at the Vostok station was carried out from 27.12.2023 to 23.01.2024. The microstructure and composition of 132 particles were analyzed by microscopic methods at the Borok State University, UrFU, and KFU. Iron-containing (magnetic) particles of cosmic dust (CD) or micrometeorites (MM) were found in the samples, similar to the same particles previously found by many authors who isolated them from various objects. A feature of the particles we found in one of the samples was the content of tin (Sn) (in metallic and oxide forms) and (metallic) copper (Cu). Considering that Sn is extremely rare in meteorites, and there were multiple finds in the samples, we believe they may be of both meteoritic and technogenic origin.
