Radio metric dating

Rated 3.91/5 based on 951 customer reviews

For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).

The object's approximate age can then be figured out using the known rate of decay of the isotope.

A few months ago I was speaking to a friend of mine, whom I first knew professionally and then became good friends.

In a separate article (Radiometric dating), we sketched in some technical detail how these dates are calculated using radiometric dating techniques.

Here is one example of an isochron, based on measurements of basaltic meteorites (in this case the resulting date is 4.4 billion years) [Basaltic1981, pg. Skeptics of old-earth geology make great hay of these examples.

For example, creationist writer Henry Morris [Morris2000, pg.
