Explanation

 Potassium-argon method is the relatively most accurate method for dating of fossils.It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar). Potassium is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites.
