摘要: Abstract Factors involved in the measurement of K-Ar ages by the40Ar-39Ar method are considered detail. It is shown that technique applicable to rocks any arbitrary age provided a suitable choice made irradiation parameters, namely integrated neutron flux and sample size. The these parameters determined principally approximate be dated lesser extent K/Ca ratio. A graphical for selecting optimum presented.
