Potassium 40 dating

Argon 40, a gas held prisoner by lava the potassium-argon method is frequently used to date lava flows whose age is between a million and a billion years when an atom of potassium 40 decays into argon 40, the argon atom produced is trapped by the crystalline structure of the lava. K-ar dating calculation so maybe i could say k initial-- the potassium-40 initial-- is going to be equal to the amount of potassium 40 we have today-- 1.

Potassium–argon dating, abbreviated k–ar dating in these materials, the decay product 40 ar is able to escape the liquid (molten) rock. 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.

Potassium 40 (k40) decays to argon 40, which is an inert gas, and to calcium potassium is present in most geological materials, making potassium-argon dating highly useful if it really works potassium is about 1/40 of the earth's crust, and about 1/10,000 of the potassium is potassium 40.
