For a long time I have had interest in cycles in all disciplines.
Many years ago I came across "Megacycles" which is the proceedings of a geological conference edited by G Williams and mentioning ~600, ~300, ~150, 74 and 37 million year cycles in geological formations. About 10 years ago I visited Russia and Crimea (Ukraine) where I attended several cycles conferences. There I met Geology Prof S Afanasiev of Moscow University. He gave me a copy of his book in Russian with translated title of "Nanocyles Method". Although I cannot read russian, I can understand the tables in the book and with a little help from a russian reading friend was able to make sense of it. His method is based on the changing period of the lunar nodal cycle which at present is 18.6 years leading to a 9.3 year cycle in weather and therefore varves. However this cycle interacts with the seasons because the same part of the cycle only happens at the same time of the year every 9.3/0.3 or 31 years. There are additional third, fourth and higher order interactions also which make longer cycles into hundreds and thousands of years. The periods of these longer cycles change much more rapidly than the main cycle and so allow very accurate dating if they can be identified. So his method is to identify cycles of short periods in varves and then look them up in a big table at 0.2 million year intervals back to 600 million years ago. He has a little data beyond that but at wider spacings. Anyway, Prof Afanasiev has determined a 586.24 million year cycle as a very important one and it appears to correspond to the mentioned ~600 million year cycle because repeated halving of the period gives 586.24, 293.12, 146.56, 73.28, 36.64 million years which agrees well with the figures in "Megacycles" and the shortest of these periods is also found in mass extinction series along with the more dominant 26.65 million years. Going even further, it is possible to identify the Elatina periods in his table at 658.28 million years ago which I think corresponds with the stated 650 to 700 million years. This would make the cause of the Elatina cycles be the interaction of the Lunar nodal cycle with the seasons. Williams originally speculated that the 12 year period was an ancient sunspot cyle, and others suggested that perhaps it was monthly varves not annual and the cycle of 12 was the year. I interpolated Prof Afansiev's tables which is at 0.2 MY interval to 600 MY and then at 4.0 MY interval, and 658.28 million years ago the cycle periods due to lunar nodal effects were 12.0769 years and 157.0 years. Note that 12.0769/0.0769 = 157.0 years, which is the period of the interaction of the nodal cycle with the seasons. These figures appear to be consistent with Williams' findings of 26 cycles in 314 years = 12.0769 years, though it is the 157 year cycle not the 314 year one that is tabulated. Another fascinating thing about the 586 million year cycle is that astronomers have identified a series of very large structures at regular spacings in space. The exact spacing is uncertain because the Hubble constant is not known accurately. However using the best estimate of the Hubble constant (71 km/s/MPc) it gives a spacing of around 590 million light years. This means that there is a wave structure in space which has a wavelength of 590 million years and so oscillates in 590 million years, in agreement with the geological cycle. Furthermore there are clear signs of further periodicities at 1/2 and 1/4 of the main periodicity in the galaxy distances also in agreement with the geological cycles. Of course the original Megacycles book mentions the connections with astronomical cycles, but it is great to see this manifesting in such a clear form.

First, no geological dating method has an accuracy of
0.01%. Four decimal place ages are ludicrous. They are just getting the KT and PC/C boundaries to about 1% ages now. Second, the length of astronomical cycles has changed considerably over the past several hundred million years. Everything was shorter back then- length of day, length of lunar month, and length of year. Identifying daily, monthly, and annular growth marks in some ancient fossils has shown this to be the case. Hard-body fossile parts only go back about 10% earth's history. Some people have claimed to seen some solar activity cycles in lake sediment patterns earlier (assuming solar cycles influence climate). |

Dear Ray,
Your approach to Cycles is a very interesting one and quite appropriate indeed. However it does not apply to Earth since as you may not have been told of it, both the formation and destruction of its relief are not linear. In clear some great events occurred in the recent past and are marked in its forms. The Greatest Principle ( and unknown ) underlining all of our Universe is the one supporting the True Geology i.e. the Law of Universal Pressure ( UPL ) , whereby all alleged attraction and repulsion are in fact due to differential of Pressure. This approach to Understanding of what we are and where we live, is really mind-boggling for all the new perspectives it opens to Mankind. Your Cycles approach is on the other hand quite appropriate relative to Pandemics ( 40 years cycle ), also to some Earthquakes recurring following some very interesting patterns. I have visited you website and it indicates a very open minded & aware person. Hence my post to you to advise not to lose time on the alleged time scale presented by the present Gogology ( or Sci000nce of Gogos ) Everything is false indeed. You could in this regards visit Don Findlay 's site, and learn about the quite correct Earth Expansion theory, completely ridiculising the hilarious PT theory supported by the official Bougredanes ! That would be a step in the right direction. http://users.indigo.net.au/don/nonsense/drivel.html Best regards -- Jean-Paul Turcaud Australia Mining Pioneer Discoverer and Legal Owner of Telfer, Nifty & Kintyre Mines The Great Sandy Desert of Australia Founder of the True Geology ~~Ignorance Is The Cosmic Sin, The One Never Forgiven ! ~~ "rick++" a écrit dans le message de news: ...

Everything was shorter back then- length of day, length of lunar month, and length of year. This is not a reason for inaccuracy. This is what he uses to determine the dates. Take the last 0.2 million years. The lunar nodal period changed from 9.15 to 9.3 years (about). The cycle that interacts with the seasons varies from 9.15/.15=61 years to 9.3/.3=31 years in that period. If this secondary cycle is found and 10 cycles are measured then it might be say 46.0 years +/- 0.5 years. That will date the deposit to maybe 0.1000 M years ago with an uncertainty of only +/-0.0017 M years. The same accuracy is achievable in the distant past once the lunar orbit is established.

ISTR there's an Eastern Mediterranean dendro scale that goes back for 9000 years, which potentially gives you 0.011(...)% accuracy. Some people have claimed to seen some solar activity cycles in lake sediment patterns earlier (assuming solar cycles influence climate). Cycles in tidally-deposited sands too, demonstrating a different number of daily tidal cycles per monthly tidal cycle. My memory is that the cycle was demonstrated in a Carboniferous-age sandstone. But the paper is on my other computer and I can't be bothered to cross the room to turn it on. -- Aidan Karley, FGS Aberdeen, Scotland, Location: 57°10'11" N, 02°08'43" W (sub-tropical Aberdeen), 0.021233 |

JOL You don't need a 9000 YEAR OLD TREE. yOU'D NEED (FOR EXAMPLE) (bLOODY cAPSlOCK KEY!) 10 1000 year-long sections of trees, with a 100 year overlap between the oldest wood in one section and the youngest wood in the next section. So you start off with trees that were felled at a known historical date (or even are still growing, because you can extract sufficient ring samples with a coring tool which is not lethal to the tree), and go back to around 1000 AD. Then using timber from a building of (say) 1100 AD, you extend the ring sequence back to around 0AD ... and so on, ad nauseam. You do need to add more caveats. Dendro is based on the observation that different individual trees respond similarly to environmental stresses, so you can correlate the ring-width patterns between individual trees. (Note, this is an observational fact, not a theory. You could demonstrate this yourself with a good tape measure, a notebook and a present-day lumber yard.) But you have to be careful to be using comparable trees - of the same species (or species that behave similarly), in similar environments (in terms of altitude, temperature, rainfall). And ideally you need to be able to replicate your chronology, which basically means having several sets of wood specimens for getting from present-day trees to your unknown date in the past. That's why it's taken the best part of 50 years of dendrochronology work to get back to 9000 BP in one part of the world. That you can only apply dendrochronology within the lifespan of a single "Methuesula" tree is one of the commonest lies propagated by creationists, whether they be christian liars or muslim liars. If you've got this from some source you consider reliable, then you need to reassess that source's credibility. -- Aidan Karley, FGS Aberdeen, Scotland, Location: 57°10'11" N, 02°08'43" W (sub-tropical Aberdeen), 0.021233 |
