We conduct magnetostratigraphy and cyclostratigraphy on an eolian red clay sequence spanning 7 – 3.1 Ma in the eastern Chinese Loess Plateau. We pay more attention to the unconventional 173-kyr obliquity modulated cycle which is associated with the secular frequency interference of orbital inclinations between Earth and Saturn. Similar to the 405-kyr eccentricity cycles, the 173-kyr obliquity band proved to be an important orbital driving component by the latest astronomical findings, and can serve as a chronometer of terrestrial air circulation reconstruction back to 7 Ma. Comparison with magneto-cyclo-bio-stratigraphic timescales of another noted eolian sequence from the adjacent area, the 173-kyr cycle is exceptionally presented as a robust recognition of the cyclical sedimentary patterns for the East Asia monsoon deposits.
