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.

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.

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. Lassen plagioclase, California (AD 1915) 0.11±0.03 Ma Sunset Crater basalt, Arizona (AD 1064-1065) 0.27±0.09 Ma; 0.25±0.15 Ma Akka Water Fall flow, Hawaii (Pleistocene) 32.3±7.2 Ma Kilauea Iki basalt, Hawaii (AD 1959) 8.5±6.8 Ma Mt.

First of all, the method is based on a simple fact about atoms—if it has too many neutrons in its nucleus, it is unstable and will change into a stable form.Etna basalt, Sicily (May 1964) 0.7±0.01 Ma Medicine Lake Highlands obsidian, Glass Mountains, California ( in the 1800-1801 Hualalai flow, Hawaii, resided in fluid and gaseous inclusions in olivine, plagioclase, and pyroxene in ultramafic xenoliths in the basalt, and was sufficient to yield "ages" of 2.6 Ma to 2960 Ma.Further confirmation comes from diamonds, which form in the mantle and are carried by explosive volcanism into the upper crust and to the surface. obtained a K-Ar isochron "age" of 6.0±0.3 Ga for 10 Zaire diamonds, it was obvious excess was inherited from the mantle source areas of the magmas. Snelling, "Discordant Potassium-Argon Model and Isochron ' Ages' for Cardenas Basalt (Middle Proterozoic) and Associated Diabase of Eastern Grand Canyon, Arizona," in R. Isotopic Fractionation is a physical separation of isotopes and a non-radioactive source of isotope ratios.

It can be caused by heating and cooling, water flow, contact between high and low concentration magma and just normal molecular motion.Therefore, to date a sample, scientist calculate how much time would be required for the unstable atoms in the sample to change into a stable form.
