Abstract

The principal geological periods from 19 to 37 Ma correspond to events during which the solar system crossed the spiral galactic streams of matter. The boundary of the Quaternary (1·5 Ma BP) was forming during the intersection of the arm of Orion-Cygnus with the solar system (2·7-0·7 Ma). There is a stable cooling trend and Matuyama-reversed epoch at that time. Oscillations with periods (TJ=0·75 2J/16y) under 2 Ma have been formed inside the solar system. The structure of rhythms with 16 periods in an octave has determined the cosmic, solar, and terrestrial processes. The laws of conservation of momentum create spectra: AJ=ST2Jwhere AJ is amplitude and S is the constant for a series of cycles. These regularities, which are very convenient for classifying cycles and land forms, permit estimation of the time of formation of geomorphological objects. Reconstructions for the last glacial period, and approximation and extrapolation of the last homogeneous part of the row, allow enhancement of the interpretation of the isotope series.
