Abstract
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 met hod. 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 de lta(34)S and delta(13)C. Spectral composition of the curve Sr-87/Sr-86 differs from the curves mentioned above. Extremums of harmonics for t he periods found coincide on time scale with boundaries of the stages of reorganization plate kinematics.
