K-Ar dating, also known as Potassium-Argon Dating, is a form of radiometric dating that measures the ratio of potassium-40 and argon-40 and radiogenic calcium-40 to potassium-40 in a mineral or rock to date the sample's age, since potassium-40 decays into both argon-40 and calcium-40 in minerals and rocks.[1]
