Which property of argon makes it useful for potassium-argon dating? It decays into potassium.

Is argon used in radiocarbon dating?

Argon–argon (or 40Ar/39Ar) dating is a radiometric dating method invented to supersede potassium-argon (K/Ar) dating in accuracy.

Is argon argon a chronometric dating technique?

The potassium-argon and argon-argon methods are used to date volcanic rock and ash deposits. Other chronometric dating methods not described here include uranium/thorium dating, oxidizable carbon ratio (OCR) dating, optically stimulated luminescence (OSL) dating, varve analysis, and obsidian hydration dating.

Which statements describes potassium-argon dating?

Which statement describes potassium-argon dating? Potassium-40 decays into argon gas over time. Argon breaks down into other elements and compounds. Potassium-40 becomes stable when trapped in rocks.
