Abstract
The methodological fundamental are suggested for investigating the transformation of geosystems of the Baikal Natural Territory characterized by different geodynamical regimes. The methodology has been developed with due regard for the openness, nonlinearity and coherence of the relationships of geosystems. The transformation of geosystems is considered in the contest of changes in its substantial properties as a result of the emergence of the transforming dynamics and evolution. It is established that the modification of geosystems of the region during the Late Cenozoic was largely caused by tectonic processes which deter mined changes in the composition of rocks, relief, climate, the pattern of the atmospheric circulation, and in the sedimentation environment. The study revealed the nonlinearity of the manifestation of the relationships of geosystems within pre-rift zones, the Angara-Vitim batholith and large faults with an increased influx of endogenous heat. It is established that an analog of the transformation of Pliocene geosystems is formed through a coherent enhancement in the natural trend of transformations in regions of intense economic activity.
