Potassium-argon dating , abbreviated K-Ar dating , is a radiometric dating method used in geochronology and archaeology . It is based on measurement of the product of the radioactive decay of an isotope of potassium into argon . Potassium is a common element found in many materials, such as feldspars, micas, clay minerals, tephra, and evaporites . In these materials, the decay product 40 Ar is able to escape the liquid rock, but starts to accumulate when the rock solidifies . The amount of . . .
The potassium-argon ( K-Ar ) isotopic dating method is especially useful for determining the age of lavas . Developed in the 1950s, it was important in developing the theory of plate tectonics and in calibrating the geologic time scale .
in the last video we gave a bit of an overview of potassium-argon dating in this video I want to go through a concrete example it'll get a little bit Matthew usually involving a little bit of algebra or a little bit of exponential decay but to really show you how you can actually figure out the age of some volcanic rock using this technique using a little bit of mathematics so we know that anything that is experiencing radioactive decay it's experiencing exponential decay and we know that we . . .
Apollo 11 mission, Ar - Ar provided a crucial dating technique . Some samples were dated using K-Ar and yielded ages in the broad range 3 to 4 Ga, testifying to the antiquity of the lunar surface, although this much had been estimated from crater densities . In contrast, the Ar - Ar dating technique provided a wealth of precise ages and thermal histories .
The method most commonly used to date the primary standard is the conventional K/Ar technique . An alternative method of calibrating the used standard is astronomical tuning (also known as orbital tuning), which arrives at a slightly different age . Applications . The primary use for 40 Ar / 39 Ar geochronology is dating metamorphic and igneous minerals . 40 Ar / 39 Ar is unlikely to provide the age of intrusions of granite as the age typically reflects the time when a mineral cooled through its . . .

DATE OF FORMATION: K-Ar . ASSESSED AGE : Haualalai (Hawaii) Basalt: AD 1800-1801: 1 .6 million years old: Mt Etna (Sicily) Basalt: 122 BC: 0 .25 million years old: Mt Etna (Sicily) Basalt: AD 1792: 0 .35 million years old: Mt Lassen (California) Plagioclase: AD 1915: 0 .11 million years old: Sunset Crater (Arizona) Basalt: AD 1064-1065: 0 .27 million years old
Potassium-argon dating is accurate from 4 .3 billion years (the age of the Earth) to about 100,000 years before the present . At 100,000 years, only 0 .0053% of the potassium-40 in a rock would have decayed to argon-40, pushing the limits of present detection devices . Eventually, potassium-argon dating may be able to provide dates as recent as . . .
For example lavas dated by K-Ar that are historic in age , usually show 1 to 2 my old ages due to trapped Ar . Such trapped Ar is not problematical when the age of the rock is in hundreds of millions of years . The dating equation used for K-Ar is: where = 0 .11 and refers to fraction of 40 K that decays to 40 Ar .
Problems and Limitations of the K/Ar dating technique . Because the K/Ar dating technique relies on the determining the absolute abundances of both 40 Ar and potassium, there is not a reliable way to determine if the assumptions are valid . Argon loss and excess argon are two common problems that may cause erroneous ages to be determined .

The common potassium-argon dating process makes use of the decay of 40 K to 40 Ar , even though much more of the 40 K decays to 40 Ca . The reason is that 40 Ca is common in minerals, and sorting out what fraction of that calcium came from potassium decay is not practical . But for special cases where the calcium content of the mineral is very low, less than 1/50th of the potassium content, it is sometimes useful to use potassium/calcium isochrons for dating .
