Question: What category of dating techniques does potassium-argon argon argon dating belong to?

Argon–argon (or 40Ar/39Ar) dating is a radiometric dating method invented to supersede potassium-argon (K/Ar) dating in accuracy.

What category of dating techniques does potassium-argon dating belong to?

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. This dating method is based upon the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks; potassium-40 also decays to calcium-40.

What is the argon-argon dating technique?

Argon–argon dating is a radioisotopic method based on the natural, spontaneous radioactive decay of an isotope of potassium, 40K, at a known rate to produce an isotope of argon, 40Ar. This method is one of the most versatile, precise and accurate of all radioisotopic dating tools applied to volcanic materials.

Is argon-argon dating absolute?

The potassium–argon (K–Ar) geochronological method is one of the oldest absolute dating methods and is based upon the occurrence of a radioactive isotope of potassium (40K), which naturally decays to a stable daughter isotope of argon (radiogenic 40Ar, also known as 40Ar*).

What is the symbol for argon-40?

Ar Argon-40 | Ar - PubChem.
