ANSWER: Sedimentary rocks cannot be dated directly using radiometric dating, which is based on the idea that when rocks are in liquid form, their radiometric clock resets. This technique is generally used to date igneous and metamorphic rock, which are rocks that were once melted due to extreme heat and pressure. Radiometric dating determines how long ago the liquid rock solidified into solid rock. Sedimentary rock on the other hand consists of sedimentary particles which were removed and deposited somewhere else by some sort of fluid generally wind and water. The sedimentary particles predate the rock which they form.

Radioactive decay can be used to date igneous rocks by assuming making some assumptions, finding the percentages of parent to daughter products and using experimentally determined half-lives. Start with the assumptions that the rock 1. That there have been no factors that have influenced the rate of radioactive decay during the "life" of the rock. Second determine the percentages of the parent to the daughter elements in the rock. The percentages can be be used to calculate the number or fractions of the half lives that have occurred to create the percentages.
Radiometric dating is a much misunderstood phenomenon. Evolutionists often misunderstand the method, assuming it gives a definite age for tested samples. Creationists also often misunderstand it, claiming that the process is inaccurate. Perhaps a good place to start this article would be to affirm that radiometric dating is not inaccurate. It is certainly incorrect, and it is certainly based on wrong assumptions, but it is not inaccurate.
