Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes . Radiometric dating is the determination of the date at which materials were formed by analyzing the decay of radioactive isotopes that were incorporated into the.

6 08 2009 - Radioactive dating is a method of dating rocks and minerals using radioactive isotopes . But the radioactive atoms used in dating techniques have been subjected to heat, .

a chemical element having the same atomic number as another (i.e., the same number of nuclear protons), but having a different atomic mass (i.e., a different. There are many applications of radioactive isotopes in various. Most absolute dates for rocks are obtained with radiometric methods.

Discover how scientists determine the age of fossils, rocks and other geologic phenomena by using the known half-lives of isotopes within each. These use radioactive minerals in rocks as geological.

As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.

Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.

In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.

Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.

The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.

Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.

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.
