One of these isotopes, potassium-40 (40K), decays slowly, with a half-life of 1.31
billion years, into argon-40 (40Ar), an inert, stable gas—hence the name
potassium-argon dating. By comparing the relative proportions of these
potassium and ...

Quaternary
Dating Methods
Potassium—argon dating is based on the decay of the radioactive isotope of
potassium, potassium40 (40K), to the relatively unreactive argon isotope 40Ar
which is a gas. The technique was developed in the 1960s and has been used
largely ...

Archaeological Chemistry
Table 13 lists radiometric methods of dating that are widely used in
archaeological studies. Potassium—Argon Dating Potassium—argon dating is
the only feasible technique for dating very old rocks that include potassium in
their composition.
One system that has been very successful in dating the ages of fossils is
potassium-argon dating. Potassium is an extremely common element. Although
most potassium isotopes aren't radioactive, one of them is, and one of its decay
products ...

Geochronology and Thermochronology by the 40Ar/39Ar Method
2.1 Potassium-Argon Dating The Ar/ Ar method of dating rocks has its
foundations in the potassium argon (K'Ar) isotopic dating method, a widely used
technique for measuring numerical ages on minerals and rocks. Since the K/Ar
method was ...

Evolution and Prehistory: The Human Challenge
Potassium-argon dating, another commonly used method of absolute dating, is
based on a technique similar to that of radiocarbon analysis. Following intense
heating, as from a volcanic eruption, radioactive potassium decays at a known
rate ...

... released, the scientists can calculate the amount of potassium-40 that was
originally in the rock. This calculation helps the scientists determine the rock's
age. The advantage of this technique over potassium-argon dating is that only
one ...

Paleoclimatology: Reconstructing Climates of the Quaternary
Compared to radiocarbon dating, potassium-argon dating is used far less in
Quaternary paleoclimatic studies. However, potassium-argon and argon-argon
dating have indirectly made major contributions to Quaternary studies (Walker,
2005).
