What is radiometric dating of fossils

The precision of a dating method depends in part on the half-life of the radioactive isotope involved.

Fundamental to stratigraphy are a set of simple principles, based on elementary geometry, empirical observation of the way these rocks are deposited today, and gravity.The discovery of radioactivity also had another side effect, although it was several more decades before its additional significance to geology became apparent and the techniques became refined. This page was last edited on 4 Decemberat The radiation causes charge to remain within the grains in structurally unstable "electron traps". By combining multiple geochronological and biostratigraphic indicators the precision of the recovered age can be improved.One of the most common isotopes used in radiometric dating is uranium or U U is often trapped in the minerals of igneous rocks that crystallize from hot, molten magma.The three most common types of isotopes used in dating the rocks the age of the fossil is implied. In igneous rocks, the potassium-argon "clock" is set the moment the rock first crystallizes from magma.
