The calcium-potassium age method is seldom used, however, because of the great abundance of nonradiogenic calcium in minerals or rocks, which masks the presence of radiogenic calcium. On the other hand, the abundance of argon in the Earth is relatively small because of its escape to the atmosphere during processes associated with volcanism. The potassium-argon dating method has been used to measure a wide variety of ages.

Potassium Argon dating is equally controversial. it is also based upon decaying potassium into argon gas and the rate of decay. Same problems as with carbon dating. Interestingly, dating a substance with both K-AR and C-14 sometimes produces dates that are a hundred million years apart. (So one or both are wrong).

Potassium Argon dating . Doesn’t carbon dating or carbon-14 dating rests on If a date obtained by radiometric dating does not match the assumed

So although the potassium-argon method has been used for dating rocks for decades, the results it has produced have tended to reinforce the geological framework that already existed. At most it may have modified the framework a little. The scores of dates that have been produced have had a life like hens in a chicken coop.

Learn how potassium-argon isotopic dating works and how it is especially Andrew. "Potassium-Argon Dating Methods Review Carbon 14 Dating with This Sample

Potassium-Argon dating has the advantage that the argon is an inert gas that does not react chemically and would not be expected to be included in the solidification of a rock, so any found inside a rock is very likely the result of radioactive decay of potassium. Since the argon will escape if the rock is melted, the dates obtained are to the last molten time for the rock.

Discussion on the inaccuracies found using the Carbon-14 dating of carbon dating. Then there was a rise in 14 CO 2 with Potassium-argon 'Dating

Potassium naturally occurs in 3 isotopes: 39 K (93.2581%), 40 K (0.0117%), 41 K (6.7302%). Two are stable, while the radioactive isotope 40 K decays with a half-life of 1.248 × 10 9 years to 40 Ca and 40 Ar. Conversion to stable 40 Ca occurs via electron emission in 89.1% of decay events.
