More Bad News for Radiometric Dating

Radiometric dating is based on index fossils whose dates were assigned long before radioactivity was discovered. This is not at all true, though it is implied by some young-Earth literature. Radiometric dating is based on the half-lives of the radioactive isotopes. These half .

Dating Methods Using Radioactive Isotopes

Prior to radiometric dating, evolution scientists used index fossils a.k.a. relative dating to ascertain the age of their discoveries. A paleontologist would take the discovered fossil to a geologist who would ask the paleontologist what other fossils (searching for an index fossil) were found near their discovery.

Isotope Systems Used for Radiometric Dating

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

How Is Radioactive Dating Used to Date Fossils?, Sciencing

Principles of Radiometric Dating. Other Uses of Isotopes. Radioactivity is an important heat source in the Earth. Elements like K, U, Th, and Rb occur in quantities large enough to release a substantial amount of heat through radioactive decay. Thus radioactive isotopes have potential as fuel for such processes as mountain building.
