The geomagnetic variations with characteristic times ranging from 0.4 to 15 ka are shown to be largely stochastic. Variations with different characteristic times appear during different time intervals and reflect accelerating and decelerating processes. The variations do not exhibit any predominant times. At the same time, almost periodic variations in the lithological characteristics are clearly seen in the wavelet dia grams of the parameters that reflect the changes in the composition (quantitative and qualitative) of ferrimag netic material; i.e., the changes in the conditions of sedimentation related to climate variations. The varia tions with periods of 5, 8.5, and 13 ka are concurrent with the similar variations in the paleomagnetic data, while the variations with a period of 3.5 ka are only observed in the magnetic parameters. We suggest that the first mentioned oscillations reflect the changes of the external (relative to the Earth) origin, whereas the changes with a period of 3.5 ka are caused by some terrestrial factors.
