Where can they find a clock to measure these huge time periods?Or on a slightly smaller scale, where can paleontologists find a clock to tell the age of fossils, or how can archeologists determine how old ancient pottery and buried artifacts are? They are mostly empty space with a denser tiny area called the nucleus and a cloud of electrons surrounding the nucleus.For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.Create a model of radioactive decay using dice and test its predictive power on dating the age of a hypothetical rock or artifact. That is what we encounter in our daily lives, right?

Yes, radioactive isotopes present in rocks and other ancient material decay atom by atom at a steady rate, much as clocks tick time away.This chain eventually ends with the formation of a stable, nonradioactive daughter nuclide.Each step in such a chain is characterized by a distinct half-life.Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning.Here I want to concentrate on another source of error, namely, processes that take place within magma chambers.
