Argon–argon dating - Wikipedia

Argon–argon (or 40 Ar/ 39 Ar) dating is a radiometric dating method invented to supersede potassium-argon (K/Ar) dating in accuracy. The older method required splitting samples into two for separate potassium and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon isotopes. Dating - Dating - Rubidium–strontium method: The radioactive decay of rubidium-87 (87Rb) to strontium-87 (87Sr) was the first widely used dating system that utilized the isochron method. Rubidium is a relatively abundant trace element in Earth’s crust and can be found in many common rock-forming minerals in which it substitutes for the major element potassium. Because rubidium is ... THE K-AR AND AR-AR DATING METHODS Introduction Both K-Ar and Ar-Ar dating techniques are based upon the decay of a naturally occurring isotope of potassium, 40K to an isotope of argon, 40Ar (Fig. 1).

If you know the answer to this question, please register to join our limited beta program and start the conversation right now! Potassium-Argon Dating. 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.

Potassium-Argon Dating Methods: K-Ar and Ar-Ar Dating

Potassium-40 decays with a half-life of 1250 million years, meaning that half of the 40 K atoms are gone after that span of time. Its decay yields argon-40 and calcium-40 in a ratio of 11 to 89. The K-Ar method works by counting these radiogenic 40 Ar atoms trapped inside minerals. For example, potassium-40 is radioactive. The number (40) refers to the sum of protons (19) and neutrons (21) in the potassium nucleus. Most potassium atoms on earth are potassium-39 because they have 20 neutrons. ... Unlike rock-dating methods, carbon-dating tends to give the correct answer when tested on material whose age is known. Potassium-Argon (K/Ar) dating is a method that applies directly the dating of rocks. It is especially useful in determining the age of volcanic rocks which often contain potassium. Like carbon, potassium has three natural isotopes, one of which is radioactive. One of the primary decay products of K-40 is Ar-40--a stable and unreactive gas.
