Chronological Methods 9 - Potassium-Argon Dating Potassium-Argon Dating Potassium-Argon dating is the only viable technique for dating very old archaeological materials. Geologists have used this method to date rocks as much as 4 billion years old. It is based on the fact that some of the radioactive isotope of Potassium, Potassium K ,decays to the gas Argon as Argon Ar By comparing the proportion of K to Ar in a sample of volcanic rock, and knowing the decay rate of K, the date that the rock formed can be determined.

Potassium K is one of the most abundant elements in the Earth's crust 2. One out of every 10, Potassium atoms is radioactive Potassium K These each have 19 protons and 21 neutrons in their nucleus. With 18 protons and 22 neutrons, the potassium argon dating method has become Argon Aran inert gas.

K-Ar Processing Limitations on K-Ar Dating The Potassium-Argon dating method is an invaluable tool for those archaeologists and paleoanthropologists studying the earliest evidence for human evolution. As with any dating technique, there are some significant limitations. Dates obtained with this method then indicate that the archaeological materials cannot be younger than the tuff or lava stratum. As the simulation of the processing of potassium-argon samples showed, the standard deviations for K-Ar dates are so large that resolution higher than about a million years is almost impossible to achieve.

Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium into argon. Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the. Isotopes of Potassium and Argon But, for the purposes of the KAr dating system​, the relative abundance of 40K is. One of the most widely used dating methods is the potassium-argon method, which has been applied to 'dating' rocks for decades, especially.

*potassium–argon dating* A dating technique [1] for certain rocks that depends on the decay of the radioisotope potassium–40 to argon–40, a process with a half-life of about × years.
