5 assumptions of radiometric dating
Radiometric dating is a method of determining the age of an artifact by assuming that on average decay rates have been constant (see below for the flaws in that assumption) and measuring the amount of radioactive decay that has occurred.
Radiometric dating is mostly used to determine the age of rocks, though a particular form of radiometric dating—called Radiocarbon dating—can date wood, cloth, skeletons, and other organic material.
To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating.
Here I want to concentrate on another source of error, namely, processes that take place within magma chambers.Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.A nuclide of an element, also called an isotope of an element, is an atom of that element that has a specific number of nucleons.Most scientists today believe that life has existed on the earth for billions of years.This belief in long ages for the earth and the existence of life is derived largely from radiometric dating.
Lava (properly called magma before it erupts) fills large underground chambers called magma chambers.
