Implications of lunar orbital periodicity from the Chaibasa tidal rhythmite (India) of late Paleoproterozoic age

Harmonic analysis of the sandstone foreset-laminae thickness series from the Chaibasa tidal rhythmite, India, clearly shows that a normal semidiurnal tidal system with synodic month of ~32 lunar days was in effect during the late Paleoproterozoic (2100–1600 Ma). The minimum number of solar days in a lunar sidereal month was ~31. Published quantitative tidal-rhythmite data of others in combination with data derived from the Chaibasa tidal rhythmite indicate long-term stability of the lunar orbit and progressive increase in the Earth-Moon distance during the Proterozoic.

Key Words: tidal rhythmite • tidal cycles • lunar orbital periodicity • Earth-Moon system • Paleoproterozoic • Chaibasa Formation
