Problems with radiometric dating of rocks, 22 comments
These books contain an exhaustive study of radiometric dates that do not fit the results evolutionists expect. Anyway, to me it seems unlikely that this chain of events would occur. I would have been perfectly happy to have an assumption of my final time deduced from the time for that first metres.
Mechanism of uranium crystallization and falling through the magma We now consider in more detail the process of fractionation that can cause dating profile good examples to be depleted at the top of magma chambers. I have no doubt that those who want to believe in an old earth will be able figure out a way to keep the overall story of problem with radiometric dating of rocks the same, regardless of how important this effect turns out to be, if that can even be determined to any reasonable precision.
Another problem with isochrons is that they can occur by mixing and other processes that result in isochrons yielding meaningless ages. Since fractionation and mixing are so common, we should expect to find isochrons often. Radioactive decay would generate a concentration of D proportional to P.
Key Articles Created or evolved? The Age of the Earth. All Snelling is doing is using language in which that particular audience would understand.
How bad are the overestimates? This can happen also if the magma is not thoroughly mixed when it erupts.
There are actually several isotopes of lead that are produced by different parent substances uraniumuraniumand thorium. The Enewetok Atoll in the Pacific Ocean is usually pointed to as an example. He is best known for the "Exploring Creation with True, this quote is frombut why should we believe scientists are any different today?
Error bars have their place, but you are correct in pointing out that they are often misunderstood not only by the general public, but by scientists who are not savvy in radiometric dating. A reply to scientific creationism.
US Geological Survey Bulletin He offers no scientific alternative. If he had data that uk cupid com dating withstand scientific scrutiny, he would publish it in scientific journals.
He offers some unrefereed papers by avowed creation scientists that there are broader problems, but even in those claims, there is nothing that questions the overall statistical accuracy.
Contamination and fractionation issues are frankly acknowledged by the geologic community. Those who promote the reliability of the method spend a lot of time impressing you with the technical details of radioactive decay, half-lives, mass-spectroscopes, etc.
Thus all of our scenarios for producing spurious parent-to-daughter ratios can be extended to yield spurious isochrons.
It is one thing to calculate a date. I think what you are missing is the chemistry involved. In fact, I think this is a very telling argument against radiometric dating.
Since then, geologists have made many tens of thousands of radiometric age determinations, and they have refined the earlier estimates. Search This Blog Search for: Bowen discovered that as magma cools in the laboratory, certain minerals crystallize first.
