If there wasn't yet enough argon in the rock to be detectable, and the equipment that was used was not sensitive enough to detect any argon, how was enough argon found that such old results were returned?
Mount st helens eruption carbon dating
There are two possible reasons that the old dates were returned. The first has to do with the reason Geocron's equipment was considered useful only for high concentrations of argon. There would always be a certain amount of argon inside the mass spectrometer left over from previous experiments. If the sample being tested is old enough to have significant argon, this leftover contamination would be statistically insignificant; so this was OK for Geocron's normal purposes.

But for a sample with little or no argon, it would produce a falsely old result. This was undoubtedly a factor in Dr.
Austin's results. The second possibility is that so-called "excess argon" could have become trapped in the Mount St. Helens magma. This is where we find the bulk of the confusing complexity in Austin's paper and in those of his critics. The papers all go into great detail describing the various ways that argon-containing compounds can be incorporated into magma. These include the occlusion of xenoliths and xenocrysts, which are basically contaminants from existing old rocks that get mixed in with the magma; and phenocrysts, which are crystals of all sorts of different minerals that form inside the rock in different ways depending on how quickly the magma cools.
Mar 24, In June of , Dr. Steven Austin took a sample of dacite from the new lava dome inside Mount St. Helens, the volcano in Washington state. The dacite sample was known to have been formed from a magma flow, and so its actual age was an established fact. Dr. Austin submitted the sample for radiometric dating to an independent laboratory in. May 20, On May 18, , a tremendous landslide on the northern side of Mount St. Helens in Washington state uncapped a violent volcanic eruption, completely altering the surrounding landscape. It is the most studied volcano in history and has reshaped thinking regarding catastrophic earth processes. The Institute for Creation Research has studied the .
Summarizing both arguments, Dr. Austin claims that xenoliths and xenocrysts were completely removed from the samples before testing, and that the wrong results are due to phenocrysts, which form to varying degrees in all magma, and thus effectively cast doubt on all potassium-argon testing done throughout the world.
It's important to note that his arguments are cogent and are based on sound geology, and are often mischaracterized by skeptics. He did not simply use the wrong kind of radiometric dating as an ignorant blunder. He was deliberately trying to illustrate that even a brand-new rock would show an ancient age, even when potassium-argon dating was properly used. Austin's critics charge that he ignored the probable likelihood that the limitations of Geochron's equipment accounts for the results, just as Geochron warned.
They also charge that he likely did not remove all the xenoliths and xenocrysts from his samples. However, neither possibility can be known for sure.

Certainly there is no doubt that the test was far outside the useful parameters of potassium-argon dating, but whereas critics say this invalidates the results, Austin concludes that his results certify that the test is universally useless.
If we allow both sides to have their say, and do not bring a bias preconditioning us to accept whatever one side says and to look only for flaws in the other side, a fair conclusion to make is that both sides make valid points. Austin does indeed identify a real potential weakness in potassium-argon dating.
However he is wrong that his phenocrysts constitute a fatal flaw in potassium-argon dating previously unknown to geology. In fact, the implications of phenocrysts were already well understood. Yes they are one of the variables, and yes, in some samples they do push the error bars.
However, the errors they introduce are in the range of a standard deviation, they are not nearly adequate to explain errors as gross as three or more orders of magnitude, which would be necessary to explain the discrepancy between the measured age of rocks and the Biblical age of the Earth.
Such variables are also a principal reason that geologists never rely on just one dating method, with no checks or balances. That would be pretty reckless. For most rocks, multiple types of radiometric dating are appropriate; and in practice, multiple samples would always be tested, not just one like Austin used.
In combination, these tests give a far more complete and accurate picture of a rock's true age than just a single potassium-argon test could.
In addition, stratigraphic and paleomagnetic data can often contribute to the picture as well. From many decades of such experience, geologists have excellent data that guides proper usage of each of these tools, and they don't include gross misuse of potassium-argon dating. What Austin did was to exploit a known caveat in radiometric dating; dramatically illustrate it with a high-profile test using the public's favorite volcano, Mount St.
Helens; and sensationalize the results in a paper that introduces nothing new to geologists, but that impresses laypeople with its detailed scientific language. Occasionally scientists do actually make huge discoveries that everyone else in their field had always missed, but such claims are wrong far more often than they're right; and Dr.
Austin and his finding that radiometric dating has always been useless is a perfect example. Please contact us with any corrections or feedback.
