New approaches to the study of the material composition and geodynamic evolution of the early Precambrian complexes

Geological interpretation of formation processes of Precambrian assemblages with a complicated structure (reconstruction of geodynamic formation settings of metamorphic rocks protoliths) requires approaches other than those applied in studying Phanerozoic objects. The current paper reports some new approaches to studying the material composition and geodynamic evolution of early Precambrian complexes. They are based on the authors’ techniques of identifying the original nature of metamorphites, statistic modeling of varied features of chemical compositions of Precambrian objects in regard to standards of geodynamic settings in the Phanerozoic and considering them in geodynamic reconstructions.
