Abstract

Abstract

When the limestone of Cambrian-Ordovician from North China is polished and painted, the thickness of its little layers is read with the help of the magnifier. Then Fast Fourier transform and spectrum analysis is made and the tide period records in day, fortnight and month is identified from the laminae in the limestone. It was found that there were 29.9 d for a lunar month in Cambrian and in Ordovician 29.8 d; that there were 384.5 d for a year in Cambrian and in Ordovician 381.7 d and that there were 22.798 h for a day in Cambrian and in Ordovician 22.963 h. It has also been learned that Earth-Moon distances in Cambrian was 58.76 Earth's radius, in Ordovician 58.96 Earth's radius and that the lunar retreat rates in Cambrian was 4.25 cm·a -1 year and in Ordovician 4.18 cm·a -1. The result shows that the velocity of the Earth rotation had been slowed down from Cambrian to Ordovician, and that the Earth-Moon distance had been increasing while the rate of lunar retreat had been decreasing.
