Potassium-argon dating, method of determining the time of origin of rocks by measuring the ratio of radioactive argon to radioactive potassium in the rock.Potassium—argon datingabbreviated K—Ar datingis a radiometric dating method used in geochronology and archaeology.
Most of the chronometric dating methods in use today are radiometric.
Potassium-Argon (K-Ar) Dating - Internet ArchiveAdditional to the primordial. This is a bad contamination problem so ca 40 is not used in any dating calculations.
Potassium argon dating, (Book, 1966) [WorldCat.org]A dating technique based on the radioactive decay of potassium (40K) to argon (40Ar).Potassium-argon or K-Ar dating is a method used by archaeologists and geologists to ascertain the date of ancient mineral deposits.

How K-Ar dating can be used to date very old volcanic rock and the things that might be buried in between.The advantage is that all the information needed for dating the sample.

The Radiometric Dating Game - Computer ScienceInterestingly, 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 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.
The potassium-argon (k-ar) isotopic dating method is especially useful for.Accessibly written by a team of international authors, the Encyclopedia of Environmental Change provides a gateway to the complex facts, concepts, techniques.
CHW3M1 - Potassium-argon datingFossils are almost never dated by radiometric methods, since they rarely contain suitable radioactive elements.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.Geologists have used this method to date rocks as much as 4 billion years old.
