Seems a local researcher in Kutzown University in PA has been researching tides
from 3.2 billion years ago. Samples of un metamorphosed sand/mud stones from
deep South African Mines have lain undisturbed for these 3.2 billion years but
when laid down, the daily mud over sand accumulations are uniformly regular.
This shows a very circular lunar orbit and favors Impactor /eject a theory
versus the capture theory --which would have had a very elliptical orbit and
produced nonuniform bands of sediments.
Seems that the moon is slowly pulling away from the earth a little bit each day
and the tides are getting longer. If you do a reverse calculation one can see
that the moon was much closer to the earth in times past. Theoretically , only
a few meters around 65 million years ago. This may have been the cause of
extinction of the dinosaurs... well the tall ones anyway.......<G>
