Latitudinal Activation of Magmatism As a Response to Cyclic Tidal Evolution in the Earth-Moon-Sun System

摘要

The oscillatory, cyclic tidal evolution of the Earth-Moon system influences the stress state of the litho-sphere. The periodicity of the tidal evolution is close to the periodicity of Bertrand cycles, while the time intervals between peak deformations of the lithosphere 40-60 Ma ago correspond to Stille cycles. This regime was revealed during investigation of solar disturbances of the Earth's orbital motion around the Earth-Moon center of mass.
