Analysis of the Preservation and Conservation Treatment of Dendrochronological Samples from Archaeological Sites in the Republic of Khakassia

In 2021 and 2022, large-scale security and rescue works were carried out in the territory of the Republic of Khakassia. During the study of burial monuments of Minusinsk Basin archaeological cultures, burial set and wooden log structures were discovered. Parts of the logs and spiles were sent to the laboratory of dendrochronology. Researchers were unable to define annual rings, due to the poor preservation of the wood. Archaeological wood is a brittle structure with an altered chemical composition. Its physical characteristics are much different from healthy wood. The article describes the search for a solution to the problem of preliminary preservation of archaeological spiles. The criteria for analysing the preservation of wood material are presented. On the basis of the experiment, it is concluded that the main methods used by restorers for the conservation of dry archaeological wood are not suitable for the treatment of dendrosamples. The question of organising the preservation of spiles with optimal temperature and humidity conditions is raised. The application of the method of digital sample preparation of spiles to accelerate the process of dating archaeological monuments is proposed.
