This imprecision (and inaccuracy) is transferred to the secondary minerals used daily by the Ar age equation will become continually more refined allowing much more accurate and precise ages to be determined.

Potassium argon isotope dating

The method most commonly used to date the primary standard is the conventional K/Ar technique.

The primary standard must be a mineral that is homogeneous, abundant and easily dated by the K/Ar and Ar methods.

The isotopes the KAr system relies on are Potassium (K) and Argon (Ar).

Potassium, an alkali metal, the Earth's eighth most abundant element is common in many rocks and rock-forming minerals.

Argon can mobilized into or out of a rock or mineral through alteration Ar and potassium, there is not a reliable way to determine if the assumptions are valid.
