Geochronology and geochemistry of neo Archaean magmatic rocks of the Ukrainian Shield.

The report includes the results of mineralogical-petrography, isotope-geochemical and structural-geological studies of crystalline rocks neoarhean US. These data are the basis for justification and explanation of geodynamic conditions and material changes in the crystalline basement in the formation rocks of neoarhean with signs of magma formation. Shown that neoarhean rocks US with features for the genesis of magmatism is hybrid dislocation formations, because their formation occurred within several stages dislocation transformations Precambrian substrate. Most clearly, they recorded two pulses formation - 3.2 and 2.8 billion years ago. The final structure of massifs neoarhean age corresponds relic formation that formed in the total transformation of crystalline basement on paleoproterozoic time.
