Austin, Geocron Laboratories, was of a type sensitive enough to only detect higher concentrations of argon gas.

Geocron clearly stated that their equipment was only capable of accurate results when the sample contained a concentration of argon high enough to be consistent with 2,000,000 years or older.

Although the exact age can't be known, the probabilities be exactly calculated. Austin's sample was known to have solidified in 1986, its argon content was clearly well below the threshhold where an amount of argon sufficiently useful for dating could have been present.

In both events, the atomic mass remains unchanged, but the number of protons changes, thus turning the element from one to another.

Young Earthers point to an infamous dating error as evidence that the Earth is only as old as the Bible says.

by Brian Dunning Filed under General Science, Natural History, Religion Skeptoid Podcast #146 March 24, 2009 Podcast transcript Today we're going to point our skeptical eye at one of the key players in the debate between geologists and Young Earthers over the age of the Earth. Steven Austin took a sample of dacite from the new lava dome inside Mount St. The dacite sample was known to have been formed from a 1986 magma flow, and so its actual age was an established fact. Austin submitted the sample for radiometric dating to an independent laboratory in Cambridge, Massachusetts.

Potassium-argon dating is done by destructively crushing and heating the sample and spectrally analyzing the resulting gases.

The equipment in use at the time at the lab employed by Dr.

The 11% of the time that potassium decays into argon and not calcium is also a probability, so this contributes to the result having a known margin of error.
