The K-Ar dating technique was one of the earliest isotope dating techniques, developed soon after the discovery of radioactive potassium, and provided an important measured in several laboratories most often using an absolute method such as a McLeod gauge to measure argon concentrations. The first published K-Ar results by such a technique.

Radiometric Dating Methods

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 (K) into argon (Ar). Potassium is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites.

For the K/Ar dating system, this decay scheme to calcium isotopes is ignored. The remaining 11% of the 40 K atoms decay to 40 Ar. It is this scheme that makes the K/Ar method work. The buildup of radiogenic 40 Ar (40 Ar*) in a closed system can be expressed by the equation: The K/Ar Dating technique.
