The amount of Argon sublimation that occurs is a function of the purity of the sample, the composition of the mother material, and a number of other factors.

These factors introduce error limits on the upper and lower bounds of dating, so that final determination of age is reliant on the environmental factors during formation, melting, and exposure to decreased pressure and/or open-air.

And we know that there's a generalized way to describe that.

And we go into more depth and kind of prove it in other Khan Academy videos.

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 (K) into argon (Ar).

By comparing the proportion of K-40 to Ar-40 in a sample of volcanic rock, and knowing the decay rate of K-40, the date that the rock formed can be determined.K has a half-life of 1.248 billion years, which makes it eminently suitable for dating rocks.Potassium is chemically incorporated into common minerals, notably hornblende, biotite and potassium feldspar, which are component minerals of igneous rocks.In the last video, we give a bit of an overview of potassium-argon dating.In this video, I want to go through a concrete example.
