Shylo Y. Earth's shape transformation modeling and its influence on geodynamic processes

The planetary dynamics of secular changes of the Earth’s shape that is determined on the base of approximation of the lithosphere surface heights that are changing during geological epochs by biaxial and triaxial ellipsoids are investigate in the dissertation. The computer modeling of lithosphere surface heights (DEMs) for different geological epochs was made on the basis of two geopaleoreconstructions models. The analysis of obtained DEMs shows at a qualitative and approximately quantitative level such results: the changes in flattening and the pole position in geological time; transformation lithosphere shape from a biaxial ellipsoid to a triaxle and vice versa as a result of action of gravitational-rotational and endogenic forces consequence in masses redistribution. The performed investigations of the Earth's lithosphere figure reorientation as a result of dynamic mass redistribution allow revealing certain regularities of structure-forming processes.
