| Summary: | Заглавие с экрана The work is devoted to the study of lamprophyres of the Altai-Sayan region. According to X-ray phase analysis, these rocks have a complex mineral composition. According to the TAS diagram, the petrochemical composition varies from alkaline picrites to trachytes. As the INAA shows, the studied samples are significantly enriched with thorium and uranium. Combining the method of electron microscopy and fission radiography (f-radiography), the occurrence forms of thorium and uranium were studied, therefore concentrating minerals were identified. |
