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.

Radiometric dating problems
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. - Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed.
Once you understand the basic science of radiometric dating, you can see Part 2 explains how scientists run into problems when they make.

Kevin Rogers submitted a comment to that article reproduced below, edited to focus on substantive issues , to which Dr Jim Mason replies. Andrew Kulikovsky spoke on one occasion and John Hartnett spoke on 2 occasions. However, we are a house 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.
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. Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger. This calls the whole radiometric dating scheme into serious question.
