Protogey

The term “geodynamics” in the context of the tectonics of lithospheric plates, as well as the concept of neo-mobilism as a whole, cannot be used for the study of the formative conditions of the early Precambrian basement of the shields of ancients platforms. Other known definitions need to be used with respect to Early Precambrian. To reasoning that the paper demonstrates the major structural-material specifics of shields which confirm that they were formed in geodynamic conditions other that neogey, during an interval over 4000 to 1900–1600 million years ago.

Purpose. To present the summary of findings of the geotectonic analysis of the basement of the Ukrainian Shield (US) and to give grounds for the specific conditions of its formation in the Early Precambrian. Methodology. Conducting analysis using the latest results of the of morphoparagenetic geological-formational studies and concepts as to the layer-block structure of the region. Results.
