Representativeness of the funds of the A. A. Chernov Geological Museum for the study of bauxite formation on Timan

The A. A. Chernov Geological Museum compiled a representative collection characterizing the processes of bauxite formation in Timan. The funds include 12 corresponding collections with a volume of 871 storage units; the history of acquisition of the funds has been analyzed. The museum collection allows fully characterizing the lithological and mineral composition, tracing the formation of deposits from source rocks to the development of a weathering profile along them with the formation of the laterite zone of bauxite. The mineral types of bauxites and the paragenesis of accessory minerals in them are characterized. It was revealed that only 40% of museum collections reflect the complete inventory of the minerals that make up bauxite. A forecast of the results of new studies of museum collections is made, which can significantly expand knowledge about the processes of bauxite formation.
