Kevin Rogers submitted a comment to that article reproduced below, edited to focus on substantive issuesto which Dr Jim Mason replies. Andrew Kulikovsky spoke on one occasion and John Hartnett spoke on 2 occasions. However, we are a radioactive dating problems divided. It can be experimentally confirmed that molten Zircon rejects lead. This is highly significant, as it means that the initial conditions are known to a high level of confidence. Jim Mason made no reference to the Concordia line and I could not find any reference to the Concordia line on any articles on the CMI website, even though it is well known e. Jim raised the issue of Helium concentrations in Zircon.
To date rocks or other objects, scientists typically use radiometric dating. In short, the ratio of radioactive and stable isotopes in the sample are determined and the measured rate at which the isotopes decay is used as an indicator of the age of the sample. However, it is typically unknown and simply assumed whether these ratios of elements are the result of radioactive decay over time or other processes that have taken place in the rock. Sometimes different methods used on the same rock produce different ages. Furthermore, the same method can produce different ages on different parts of the same rock. Sometimes these are close but other times they are radioactive dating problems different.
Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava. Lava properly called magma before it erupts fills large underground chambers called magma chambers. Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios.

By GriffonDecember radioactive dating problems, in Physics. I've been poking about on the internet again as you do and found a whole load of stuff by creationists about the problems with carbon 14 radiometric dating. Specifically they report with some glee that coal has been found to contain measurable amounts of carbon14 which it should not of course because it is about million years old and dates from the carboniferous period. C14 has a half life of years and is only good to date objects to 50, years or so. Although I can find any number of references to this seemingly vital finding on the creationist sites, I can find almost no attempt to refute or explain this anomaly on serious science sites.
What was interesting though, was that the majority of the class came up with the same answer he did. His point in this exercise was to show how one mistake or one piece of missing information or one misperception or bias can cause you to come to the wrong conclusion or answer. His goal for us was to become critical thinkers and to question everything, including well known psychological theories. I just disagree with your conclusion: Emily, of radioactive dating problems I offered to do the cooking and prep for the people I invited.
How often do I apologize. Ask their wives and you may hear a different story.
But what people want when they visit are their sweet and savory crepes, whipped with wheat or buckwheat imported from France. Whether you are coming for breakfast or lunch, you will have a hard time choosing from the large number of fillings wrapped in light, delicious crepes.
