The eruption of Etna A stream of lava at the time of the eruption of Etna.Ancient lava flows are dated using the Potassium- Argon method.Other techniques allow the dating of extraordinary very varied ages.For example, the Uranium-Lead method allows measuring the age of 4.5 million of years on earth, and that of Uranium-Thorium to evaluate up to several hundred of thousand of years of recent geological years like those of corals. In old rocks, there will be less potassium present than was required to form the mineral, because some. May 2015 - 5 min - Uploaded by upfront4u RADIOMETRIC DATING OF ROCKS..

Answer: Radiometric dating does not fit with the young earth view.

The dose of potassium-40 and argon-40 requires the use of refined mass spectrometry carried out in specialised laboratories.

This method allows the dating of lava and volcanic rocks whose age varies from between 100 000 years and 2 million years.

What are the best types of rocks to use for radiometric dating. Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.

Every age scientists expect you to trust based on radiometric dating (a). Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the. These radioactive isotopes are unstable, decaying over time.
