Later, more of the crustal rock would be incorporated by melting into the magma, and thus the magma would be richer in uranium and thorium and poorer in lead. But have you ever thought about where you would get that information from, since you can't travel back in time to measure it? Then you have to remember that sometimes one has repeated melting and solidification, introducing more complications.
Thus geologists assume that the lead in zircons resulted from radioactive decay. Those who promote the reliability of the method spend a lot of time impressing you with the details of radioactive decay, half-lives, mass-spectroscopes, etc. Let N p be the concentration of some non-radiogenic not generated by radioactive decay isotope of D at point p.
It simply says such and such happened, then another day begins. Humphreys has produced a model that is a bit similar in that it involves a stretching out of the universe. As is often the case, there are problems on both sides. Light, spouting prophecies and claiming to know what will happen does not help anyone, my anxiety made least of all fellow christians.
This is a very interesing point, which i looked into more closely. Humans are not an exception to the laws of science. Using mother daughter methods it is possible to date rocks that solidified out of their molten state billions of years ago. This would require similar diffusion rates in cold meteorites as in warm crustal zircons.
However, there are other kinds of evidence for truth. The Bible answers those questions, of course, but is it true? Try not to use creationist source material, but physics textbooks.
The elements rubidium and strontium are found in many rocks. But evolution over millions of years is just a story, an assumption, a way of interpreting the evidence. It seems that your argument is that God stays the same and that science changes all the time, and thus science is better. If this happens, the isochron can be measuring an age older than the date of the eruption. Even though modern physics and logic suggest things that happened in the bible are impossible, I happen to believe that they did indeed happen the way bible said they did.
The relative concentrations of lead isotopes are measured in the vicinity of a rock. They focus on the technicalities of radioactive decay, etc. As the ocean floor sinks, it encounters increasing pressures and temperatures within the crust. He will simply say the assumptions about the past were wrong and then invent different assumptions to give an age that he likes. Hayes has brought it up, we can take it into account, right?
The fatal flaw with radioactive dating methods Biblical Geology

Thus we need to have an uneven distribution of D relative to N at the start. Without knowing the starting time it is impossible to establish the time for the race. The electric charge distribution would create an attraction between the uranium compound and a crystallizing mineral, enabling uranium to be incorporated. There are many other flaws in the arguments, but these are the most obvious. Eye witness accounts are essential to recording credible evidence of history.
It is also common to sometimes put our names near the begging of a business letter or a book, in the letterhead or the cover or front pages of a book. They assume that initially the magma was well mixed to assure an even concentration of lead isotopes, but that uranium or thorium were unevenly distributed initially. Two kinds of magma and implications for radiometric dating It turns out that magma has two sources, ocean plates and material from the continents crustal rock.
More Bad News for Radiometric Dating
Just recall that all such dating exercises are driven by the million-year worldview of the researcher. Look, I have no problem with anyone believing whatever it is they want to believe and I expect the same consideration to be given to me. We end up with part of an entire generation who fall behind their peers, are largely mocked by less ignorant cultures and contribute to the growing mediocrity of the U.
The fatal flaw with radioactive dating methods
Would it make any difference if the watch we were using was more accurate? There are also transitional fossils and organisms in the misguided definition of the word you are using. Are you telling me that he has been swimming at that speed for the whole race? That is, the more daughter product relative to parent product, the greater the age. Also your assumption that scientists collude is nonsense.
In which case the earth would have been too cold to have liquid water and allow life to survive. So we have two kinds of processes taking place. Scientists exclude what we think are anomalous data all the time. Such a high melting point would imply fractionation in the magma.
And isochron dating does not eliminate the need to know the original ratio. But I do agree with the creationists in this case because radiometric dating is seemingly unreliable. This is not necessarily a problem for radiometric dating, because it can be taken into account.
This reaction will continue until the last mineral in the series, biotite mica, is formed. This process is known as fractional crystallization. Although more than one rock type can be generated from a single magma, apparently other mechanisms also exist to generate magmas of quite varied chemical compositions.
We need to consider the implications of this for radiometric dating. Many people assume that the dates scientists quote of millions of years are as reliable as our knowledge of the structure of the atom or nuclear power. So the isochron can be measuring an older age than the time at which the magma solidified. Then provide empirical evidence of what the original state of the matter was and the math you used to arrive at the date you have established.

- Later on the magma is poor in iron, magnesium, and calcium and rich in uranium, thorium, sodium, and potassium.
- Such uncertainties are usually glossed over, especially when radioactive dates are communicated to the public and, more importantly, to students.
- Such a distribution would give the appearance of age.
- It is possible that the reason is that uranium-lead dates so rarely agree with the correct dates.
- Well, all the best and keep the interesting articles coming.
For example, carbon dating can be applied to manuscripts from ancient Egypt, and match up with the known dates of those documents. It depends how fast it happened. These values may be taken as an indication of the very low abundance of these elements in the mantle and crust of the Earth. Even if there was a life extinction event during that time there would still be evidence of civilization with a population that large.
But, is this test always done? This changes the chemical identity of the atom. Rb and Sr are still considered to be trace elements, even when incorporated into the lattice. It will enter later, dating harley riders probably due to melting of materials in which it is embedded.
This would be very interesting, and would cause geologists to have to re-write many books, but the general story of geology would stand. Scientists love nothing better than to tear some other scientists pet theories apart. Consequently, someone dating fractional crystallization can produce igneous rocks having a wide range of compositions. This will cause an apparent large age.
- Did you know that early christians thought that Nero was the anti-christ because of how he persecuted them and that the alternate spelling of his name, Neron, added up to the symbolical number?
- Separation of minerals by fractional crystallization.
- Rubidium readily substitutes for potassium in the crystal lattice of minerals, and strontium readily substitutes for calcium.
- Tradition would dictate that the creation account was revealed to Moses by God.
- The mineral makeup of an igneous rock is ultimately determined by the chemical composition of the magma from which it crystallized.
Every age quoted is based on assumptions. People can easily be convinced and believe something happened to them if they want to believe it, its basic psychology. The problem for long ages is worse than you think. Suppose P p is the concentration of parent at a point p in a rock.
