 The proposed model of "Global Geodynamics", which, in contrast to global tectonics, includes an overview of all areas of the Earth and considers the thermal structure of the Earth as a single price. The advantages and disadvantages of the Tectonic map of Ukraine at a scale of 1: 1,000,000 and the proposed method of compiling a tectonic map of the Ukrainian shield at a scale of 1: 500,000 are considered. due to the state linear linear and rotational displacements of the lithosphere blocks and shear deformations along the fault zone. This confirms the nature of the development of the shield for the plate tectonic model. For the first time for the western part of the Ukrainian shield the stage of kinematic development of the earth's crust, which took place in the early Proterozoic 2.45; 2.30; 2.05; 1.99; 1.85-1.73 billion years ago, and which can be used for further geodynamic buildings. The nature of rock deformations and reconstructed paleon stresses of the Sushchano-State fault zone of the Volyn megablock of the Ukrainian Shield have been studied. It has been established that the Sushchano-Perzhanskaya fault zone has been identified in five stages. The formation of support contributed to the creation of diverse chipping zones, the relative age, which is set for the character in question L- and R-chips. A computer database of kinematic data has been compiled, designed with graphic material for the deformation mesostructures of the Sorokin zone and the Kryvyi Rih basin of the USh. Reconstructed pale-stressed states, selected stages of deformation within the central and northern parts of the Sorokin zone; installations, features, special character of deformation of rocks of the Surozh gold ore manifestation - conditions of pure horizontal shift. A tectonic model of the earth's crust and upper mantle to a depth of 400 km was constructed according to the profile of the Mlinets PES on the basis of synthesis of geological and geophysical information.
