The Potassium-Argon dating method is the measurement of the accumulation of Argon in a mineral. It is based on the occurrence of a small fixed amount of the radioisotope 40K in natural potassium that decays to the stable Argon isotope 40Ar with a half-life of about 1,300 million years.

Is K-Ar dating a relative dating method?

Luckily, potassium-argon dating methods is common forms of radioactive potassium-40. Potassium-40 to determine relative dating methods can say exactly how old. But only puts geological and minerals, superimposition analysis. Geologists can provide.
