This is not only true for recent and young volcanics, but for ancient volcanics such as the Middle Proterozoic Cardenas Basalt of eastern Grand Canyon. In conclusion, the fact that all the primordial argon has not been released yet from the earth's deep interior is consistent with a young Earth.

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.

While the apparent ages might be slightly different, they are still excessive because of excess argon and are in the same ballpark as those listed above.

So the argument that excess argon produces erroneous apparent ages is still correct.

For the original sources of these data, see the references in A. Snelling, "The Cause of Anomalous Potassium-Argon ' Ages' for Recent Andesite Flows at Mt.

Ngauruhoe, New Zealand, and the Implications for Potassium-Argon ' Dating'," R.

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

Ar Analyses of Historic Lava Flows.” Nevertheless, this is no way changes the argument in question.

They rarely reach more than about 3 kilometres radius from the vent.basalt: volcanic rock (or lava) containing less than 54% silica, commonly producing more effusive, runny and less explosive lava [basaltic]basaltic andesite: a volcanic rock intermediate in composition between basalt and andesite, common in volcanic arcsbasement rocks: crystalline, indurated or metamorphosed rocks that underlie the softer sedimentary or volcanic cover rocks, and which are generally older than c.
