Tectonics and magmatism are inextricably interconnected phenomena of the single tectonic-magmatic process. Their scales must be a priori commensurate. However, in practice of geological work, small magmatic complexes often do not correspond to extended magma-controlling structures, due to the notorious complex creation that distorts the geological history, leads to genetic misconceptions and errors in forecasting and searching for mineralization. The urgency of the problem of correct identification of magmatic complexes is illustrated by examples on the materials of large tectonic structures of the Urals, Siberia and the Far East of Russia.

Keywords: tectonomagmatic processes, tectonic structures, magmatic compexes, distortion of geological history due to complex creation, errors in mineralization forecasting.
