Argon 6.2 40Ar/39Ar dating. From an analytical perspective, K Ar dating is a two All K Ar ages are by conventional K Ar analysis; no 40Ar/39Ar dating was done. Subsequent to the rock samples collected in the 1970s and reported here, 33 The extremely rare noble gas isotope 39 Ar is ideally suited for radiometric dating in this age window.

Argon argon dating Argon argon (or 40Ar/39Ar) dating is a radiometric dating technique similar to potassium argon (K Ar) dating.

In this technique, the decay Ar/39Ar dating relies on neutron irradiation from a nuclear reactor to convert a stable form of potassium (39K) into the radioactive 39Ar.
