Radiocarbon dating can be used to date objects as old as, search form
Let me illustrate the circulation patterns of argon in the earth's crust. Thus, the available evidence is sufficient to validate the radiocarbon method of age determination with an Age limit for dating in california of about 10 percent for twice as long a period as the creation scenario calls for.
We have numerous reports in hand from respected Accelerator Mass Spectrometry labs providing Carbon test results on dinosaur BONE in the twenty to thirty thousand radiocarbon year range, well below the 55, year acceptable detection limit.
Additionally, a summary is presented of all 63 previously published results for iron-based materials and 29 new results that have not been published previously.
Slusher asserted that the best known value of the branching ratio was not always used in computing K-Ar radiometric ages. If a date is too old, one can say that the mineral did not melt with the lava.
Slusher and Rybka also propose that neutrinos can change decay rates, citing an hypothesis by Dudley 40 that decay is triggered by neutrinos in a "neutrino sea" and that changes in the neutrino flux might affect decay rates. Because of the chemical similarity of carbon and carbon, it is unlikely that such plants could deviate much from the ratio of C to C found in the atmosphere.
But that does not appear to be the case, at least especially on the geologic column. On page the author explains some of the professional care which stands behind his use of the carbon method.

In this way, sites that do not have radioactive or other materials for dating can be given a reliable age estimate. Survival is usually far shorter for the bones buried in warmer regions. Many dating methods seem to give about the same ages on meteorites.
Various living samples give very different ratios. Here is another quote from Woodmorappe about isochrons, since some people think that mixing scenarios or other age-altering scenarios are unlikely: Sanderson was amazed in to find that there was an accurate representation of the American dinosaur Brachiosaurus, which was almost totally unknown to the general public at that time.
I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions.
It wouldn't require many internal cracks to allow a ten millionth part of argon to enter. They are reproduced below.
Here is another way that K-Ar dates can be too old: We have found un-mineralized dinosaur bones. First, many igneous formations span many periods, and so have little constraint on what period they could belong to.
Chronological dating - Wikipedia
The problems are compounded because many of the parent and daughter substances are mobile, to some extent.
On February 12,the journal Acta Histochemica published a paper by Armitage describing the discovery of soft tissue in the triceratops horn.
As an example Pinnacle Point 's caves, in the southern coast of South Africaprovided evidence that marine resources shellfish have been regularly exploited by humans as ofyears ago. Contrary to creationist Barnes' totally discredited claims, which I've covered in Topic 11the earth's magnetic field dipole moment has, indeed, increased and decreased over time.
But if we really understand what is going on, then we should be able to detect discrepant dates as they are being measured, and not just due to their divergence from other dates. In addition, this would cause a gradient of Ar40 concentrations in the air, with higher concentrations near the ground.
