摘要: The tidal rhythmites in the Proterozoic Big Cottonwood Formation (BCC) of Utah, Neoproterozoic Elatina Flinders Range Southern Australia, and lower Pennsylvanian Mansfield Indiana indicate that rate retreat lunar orbit has been approximately constant since late Precambrian closely matches present epoch value determined from Apollo lasers. Examination a new core leads to slightly revised length day (LOD) modified values for other Earth-Moon dynamical parameters, thus implying 900 million years ago, reported earlier by Sonett et al. [1996] should be ∼ 18.9 hrs.
