What type of rock works best for radioactive dating

In beta decay, a neutron turns into a proton by emitting a beta particle, which is an electron click for credit. As someone who has studied radioactivity in detail, I have always been a bit amused by the assertion that radioactive dating is a precise way to determine the age of an object. This false notion is often promoted when radioactive dates are listed with utterly unrealistic error bars. In this report , for example, we are told that using one radioactive dating technique, a lunar rock sample is 4, million years old, plus or minus 23 million years old. Of course, that error estimate is complete nonsense.

How can radioactive decay be used to date rocks?

Radioactive dating, or more accurately radiometric dating, is a method used in geology and archeology to date rocks and specimens based on the presence and amounts of radioactive elements or radioactive isotopes of elements. Knowing how fast a radioactive element decays allows us to determine the amount of original material present when the substance was formed. By knowing this, we can estimate the age of the substance. The best rocks to use for radiometric dating are igneous rocks. In this type of rock, the

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.
