Track dating

The commonest minerals dated using this method are zircon and apatite.Zircon is common in volcanic ash, and its crystals contain very small amounts of the uranium-238 isotope.Although it is not abundant in igneous rocks, it is sufficiently common to be used for the purposes of radiometric dating.It has two properties which make it useful for this purpose.

Different approaches may be best for different types of sample material.Close examination must now be given to the assumptions involved in fission track dating.The first of these, noted above, is that the induced track count is performed on identical material to the spontaneous track count.The Institute for Creation Research (ICR) has recently completed their multi-year project dealing with a scientific evaluation of the age of the earth and produced two book publications and an accompanying DVD.Within their research, the ICR research team makes many claims that geological evidence, including their findings dealing with dating rocks using the fission track dating method, provides substantial evidence for a young earth.

In this article we shall discuss the basis of the U-Pb and Pb-Pb methods, and also fission track dating.
