Radiogenic dating methods madison beer and cody simpson dating
Depending on what is being dated (what it is composed of, where it resides) some methods will be more effective than others.
On this page, you will find descriptions of several of the most popular and useful methods that exist today.
By far, the most well-known type of radiometric dating is method using the radioactive isotope of carbon, carbon-14.
Every living organism on the planet contains the element carbon.
This means that if the amounts of C-14 and N-14 in a sample are known, then its age can be calculated for a wide range of years.
Several half-lives can pass and still leave measurable amounts radioactive carbon present in the sample.
These two decay pathways have different half-lives that have been measured and recorded.
It is especially disposed to dating minerals such as Zircon.
Zircon is a fairly abundant mineral that exists in many forms in the environment, and because of its chemical structure Uranium is easily incorporated into its molecules.
When a life form is alive and undergoing some sort of respiration, it will be gaining C-14 at a relatively high rate (it will equilibrate with the C-14 in the atmosphere) and losing it to decay at a different rate.
However, when the life form dies and is buried or otherwise stops interacting with atmospheric gases there will be no further increase in the amount of radioactive carbon in the system.
Carbon-14 has two more neutrons than stable carbon, and thus has a mass that is greater by two.
