Geosystems of the Barguzin Ridge

Abstract

The study of geosystems of geodynamically active territories and their mapping is one of the urgent tasks of modern geographical research. The long period of formation and development of the Barguzin ridge determined the specifics of geosystems and their components. The conducted research allowed us to identify five physical and geographical areas, each of which has its own unique features. Within the large tectonic faults, which are characterized by an influx of endogenous heat and hot mineral springs are common, there is the largest accumulation of Miocene-Pliocene relics that have been preserved here since the Pleistocene cold snap. The development of the dark coniferous taiga is confined to the areas of distribution of acidic granites. Currently, pyrogenic impact is of great importance in the development of geosystems of the Barguzin ridge, which is reflected in the spread of derived forests that have arisen in the places of large fires. Frequent fires can cause the disappearance of dark coniferous taiga, as the process of restoring geosystems will be replaced by their transformation. The specifics of geosystems and their current state are reflected in the medium-scale map of geosystems of the central part of the western macroslope of the Barguzin ridge, which is presented in the article. The map was made for the first time at a scale of 1: 200000 to the level of facies groups.
