Addressing the issues of assessing and predicting environmental changes in regions is the basis of modern geographical research. It is based on identifying the direction of geosystem transformation consisting of a large number of variable components and their interconnections. The task is compounded by the need to study geosystems developing under climatic and geodynamic changes. The paper presents the research results of the transformation of geosystems of the Lena-Angara plateau, which is located on the southeastern outskirts of the Siberian Platform and is a pre-rift structure of the Baikal rift zone. The specificity of the spatiotemporal transformations of geosystems associated with the manifestation of neotectonic processes and climatic changes in the Late Cenozoic is revealed. It was determined that within the plateau there were four periods of irreversible transformations of geosystems caused by the synchronous manifestation of climatic and neotectonic processes. Changes resulted from neotectonic processes led to the formation of landscape boundaries coinciding with deep faults and blocks of the earth‘s crust.
