What is potassium argon dating used for
Potassium-argon and argon-argon dating allow us to date rocks that are much older than this potassium-40 decays to argon-40 and calcium-40, with a half-life of 125 billion years the ratio of potassium-40 to argon-40 trapped in rock can be used to determine how long it is since the rock has solidified. What are elements used for radioactive dating potassium argon dating potassium-40 decays to argon-40 carbon-14 dating. Used in fluorescent lights and in welding, this element gets its name from the greek word for lazy, an homage to how little it reacts to form compounds on earth, the vast majority of argon is the isotope argon-40, which arises from the radioactive decay of potassium-40, according to chemicool.

Potassium-argon (k-ar) dating is the most widely applied technique of radiometric dating potassium is a component in many common minerals and can be used to determine the ages of igneous and metamorphic rocks the potassium-argon dating method is the measurement of the accumulation of argon in a mineral. 1 radiocarbon dating 2 paleomagnetic dating 3 potassium-argon dating 4 dna analysis. Most of the argon isotope literature deals with measurement of 40 ar for use in k-ar age-dating and has the added advantage that potassium and argon are. Potassium-argon or k-ar dating is a geochronological method used in many geoscience disciplines it is based on measuring the products of the radioactive decay of potassium (k), which is a common element found in materials such as micas, clay minerals, tephra and evaporites.
