Examples of inaccurate radiometric dating. An index to creationist claims
It was already known that radium was an intermediate product of the decay of uranium.

Now, consider an intrusive flow, which cools within the earth. The only two quantities in the exponent of a decay rate equation are the half-life and the time.
This has been done for the "Methuselah of trees", the bristlecone pine trees, which grow very slowly and live up to 6, years. Then we can average them to get an average age for this rock.
Convective mantle and radioactivity InThomson had been made Lord Kelvin in appreciation of his many scientific accomplishments.
It was heralded as the missing link for about forty years, until when the Piltdown was exposed as a fraud. Now, several factors need to be considered when evaluating how often methods give expected ages on the geologic column.
It has been estimated that it would have taken less than years for the C to reach its present level of concentration. There are so many mechanisms that it is hard to know what pattern to expect, and one does not need to rely on any one of them such as more argon in the magma in the past to account for problems in K-Ar dating.
Also, they appear to have been covered over quickly. Another point to note is that even after it cools, the lava or magma may still have many cracks in it, permitting argon to flow.
F The process has always been uniform.
There are hundreds of skeletal examples of those listed above which prove only that there were apes and that there were men.
Suppose the partial pressure of argon 40 in the environment is p.
And such flows often have a large internal scatter of dates, but these dates are not considered as anomalies because of the unrestricted biostratigraphic limit. None of the dozens of processes indicate that the earth is more than half a billion years old, far short of the 4 to 5 billion years which is commonly taught.
Dendrochronology has produced master tree-ring indices off of the Douglas Fir and Bristlecone Pine in the south-west US that allows for the accurate dating of events and climatic conditions of the past years.
AroundWilliam Smith in England, who was a canal surveyor, noticed that he could map out great tracts of rocks on the basis of their contained fossils. The special theory of evolution is sometimes called horizontal variation. This article is intended to be an informative summary of the creation and evolution topics.
We now consider whether they can explain the observed dates. Why a low anomaly percentage is meaningless One of the main arguments in favor of radiometric dating is that so many dates agree with each other, that is, with the date expected for their geologic period.
It's not surprising that K-Ar dates often agree with the assumed dates of their geological periods, since the dates of the geological periods were largely inferred from K-Ar dating. Public Opinion Introduction The television, newspapers, and textbooks commonly proclaim, as though it were proven fact, that the earth is 4 to 5 billion years old.
Rejecting fossil data cannot be supported by proof. It supposes that all of the processes that we see in nature today, have always been occurring at the same rate that they do today.
By this law, incredibly complex life forms could never be formed from simple raw materials, even if you waited a trillion years. So to assume that the K-Ar dates, Rb-Sr dates, and U-Pb dates all reflect the age of the lava, one would have to assume that this lava had no Sr, no Pb, and that all the argon escaped when the beads formed.
I don't object to having some hard evidence that there are real agreements between different methods on the geologic column, if someone can provide it.
Online dating rarely works it is all based upon the beginning assumption that the general theory of evolution is correct and that any evidence to the contrary, no matter how vast, has to be wrong.
