геодинаміка

Significance of magmatism as a marker of geodynamic processes of the past geological epochs is considered. A scheme of phased studies of magmatic rocks is given as well as their generalization and connection to tectonic structures. On the basis of formation analysis and mineral-geochemical indicators of the Cainozoic volcanites it is proved that geological development of the Ukrainian Carpathians during Cainozoic go on a collision geodynamic regime type.

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. Lithosphere Ukrainian shield (US) presented of the mosaic blocks that have a different configurations in a different times and belong to different continental fragment in early Archaean probably. Geodynamic models are exist in the present time of the northwestern (Volyn, Bug, Rosinsk blocks) and central (Ingul block) parts of the US that are not related. Construction of a common model geodynamic development of the entire western part of the US is not yet possible in the Proterozoic that is important to solve paleogeodynamic issues in the Precambrian.
