Based on the methods of statistical and combinatorial analysis of more than 70 empirical geochronometric scales of the Phanerozoic, cyclic regularities were revealed with high reliability, which allowed us to calculate the parameters of the galactic orbit of the Solar System, to consider the connection of general planetary geological processes with the position of the Solar System in the galactic orbit, and to construct a global theoretical scale of the Phanerozoic, subdivided into ages and combinations of ages.
