Аннотация: Latent periodicity in the phanerozoic isotope age-curves of delta(34)S, delta(13)C, and Sr-87/Sr-86 was established by spectral analysis method. The most representative periods are 1200-1500 Myr and 550-570 Myr that are trends and cycles with periods 200 and 150 Myr for curves delta(34)S and delta(13)C. Spectral composition of the Показать полностьюcurve Sr-87/Sr-86 differs from the curves mentioned above. Extremums of harmonics for the periods found coincide on time scale with boundaries of the stages of reorganization plate kinematics.
