Geological formations and lithodynamic complexes
The author reviews the approaches of different researchers to defining geological formations. It is shown that tectonic and stage approach developed by V.Ye.Khain became outdated with the change of paradigm. Lithodynamic complexes used in geotectonics have nothing to do with geological formations. Formation analysis is being developed as a means of getting information by defining regularities in spatial and temporal distribution of rock association bodies which are united by material composition and internal structure.
