Also, when samples of volcanic rocks are analyzed for K-Ar and Ar-Ar "dating," the investigators can never really be sure therefore that whatever K since their formation, or whether some or all of it came from the mantle with the magmas. Weis, "Helium, Neon and Argon Isotope Systematics in Kerguelen Ultramafic Xenoliths: Implications for Mantle Source Signatures," S.

This could even be the case when the K-Ar and Ar-Ar analyses yield "dates" compatible with other radioisotopic "dating" systems and/or with fossil "dating" based on evolutionary assumptions.

Furthermore, there would be no way of knowing, because the Ar not from radioactive decay, except of course by external assumptions about the ages of the rocks.

Thus all K-Ar and Ar-Ar "dates" of volcanic rocks are questionable, as well as fossil "dates" calibrated by them.

For more than three decades potassium-argon (K-Ar) and argon-argon (Ar-Ar) dating of rocks has been crucial in underpinning the billions of years for Earth history claimed by evolutionists.
