“…Neap-spring counting previously report- ed for the Elatina Formation has vielded a mean rate of lunar retreat from the late Precambrian to the present (6). The lunar orbital period has also been inferred from studies of intertidal Devonian corals and other biota (9).…”

“…W e compared three ligands-complexes of specific peptide and M H C molecules, complexes of the bacterial superantigen TSST (toxic shock syndrome toxin) and M H C molecules, and monovalent antibodies to CD3 (anti-CD3)-with respect to their ability to trigger TCRs and activate T cells (6). All three ligands induced a dosedependent T C R down-regulation, but the efficiencies and kinetics differed (Fig.…”

The tidal rhythmites in the Proterozoic Big Cottonwood Formation (Utah, United States), the Neoproterozoic Elatina Formation of the Flinders Range (southern Australia), and the Lower Pennsylvanian Pottsville Formation (Alabama, United States) and Mansfield Formation (Indiana, United States) indicate that the rate of retreat of the lunar orbit is dxi/dt approximately k2 sin(2delta) (where xi is the Earth-moon radius vector, k2 is the tidal Love number, and delta is the tidal lag angle) and that this rate has been approximately constant since the late Precambrian. When the contribution to tidal friction from the sun is taken into account, these data imply that the length of the terrestrial day 900 million years ago was approximately18 hours.

“…Recent studies of tidal rhythmites and bundles have contributed to the recognition of tidal environments and tidal cycles (e.g., Archer et al 1991;Williams 1991;Archer 1996). The tidal periodicities in rhythmites have been used to interpret orbital mechanics (e.g., Sonett et al 1988). Although harmonic analyses from drilled cores (Fig.…”

“…Thirty years ago it was widely discussed in the liter ature whether the varve thickness in the late Precam brian (~700 Ma) Elatina formation, South Australia, according to the Williams data (Williams and Sonett, 1985;Sonett et al, 1988) depends on solar activity (or on other factors). The author of the published series finally accepted the hypothesis that lamina size depends on tidal variations.…”

Prolonged variations in the duration of the Schwabe-Wolf (~11 years) and Suess (~200 years) cycles have been analyzed using different experimental data. It was shown that the duration of the Schwabe-Wolf cycle on a 2000 year time scale varied monotonically (on average, increasing) and cyclically (with a period of several hundred years); periods of 10.4, 11.0, and 11.4 years predominate on the occurrence fre quency histogram. The Suess cycle duration was 200-290 years during the Holocene and tended to increase in the past. This was accompanied by cyclic variations with a period of 2300-2500 years corresponding to the Hallstatt cycle. Arguments for the assumption that the Suess cycle duration decreased by a factor of more than 1.5 over the past half billion years are presented. This may indicate that the solar rotation characteristics and convection zone parameters varied on long time scales during the Sun's evolution on the main sequence.
