| Abstract: | The studies on stromatolites occurring in the Mesoproterozoic Tieling Formation, Zhoukoudian, Beijing indicate that the thickness of bright-dark lamina pairs in the stromatolites shows periodic variations, which are interpreted as monthly and seasonal rhythms. On the basis of the S-shaped stromatolites, some preliminary paleo-astronomic parameters have been obtained as follows: In the late Mesoproterozoic (1000 Ma ago) there were at least 516±20 d, 12.9 ±0.5 months per year, 40 d per month and at most 16.99 ± 0.66 h per day, and paleo-obliquity of the ecliptic was 29.2°-30.6°. |
