Clay fractions and glauconite (clays) lose 30-80% of the 39 Ar produced by the nuclear transformation 39 K( n, p ) 39 Ar during irradiation in a reactor. As a result it has not been possible to date clays by the 40 Ar- 39 Ar step-heating technique. New observations on 39 Ar loss in clays are presented, and the transport behavior of the 39 Ar recoils in the elementary clay particle was simulated by the Monte-Carlo method. A new procedure for dating clays by the 40 Ar- 39 Ar step-heating technique is proposed. The use of an aliquot of the same clay, along with its K-Ar age, is suggested as a specific monitor of the irradiated sample, enabling stepwise 40 Ar- 39 Ar analysis. This specific monitor monitors, without changes in the experimental setup, the integral of 39 Ar production from 39 K during irradiation and its retention in the solid substrate. The new procedure was successfully demonstrated on the geochronological standard glauconite GL-O.
