This has a standard deviation, so it also contributes to the margin of error. So when my result says the sample was 2. The bell curve of probable age starts at about 1. So whether you call it an exact science or not is a matter of linguistics. Although the exact age can't be known, the probabilities can be exactly calculated. Austin's sample was known to have solidified inits argon content was clearly well below the threshhold where an amount of argon sufficiently useful for dating could have been present.

And even that threshhold applies to only the most sensitive detection equipment. 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.

Austin, Geocron Laboratorieswas 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, years or older.

And so, by any standard, it was scientifically meaningless for Dr. Austin to apply Geocron's potassium-argon dating to his sample of dacite known to be only six years old. But let's ask the obvious question.

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? 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. The second possibility is that so-called "excess argon" could have become trapped in the Mount St. 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. Page after page of chemical compositions, mineral breakdowns, charts and graphs, and all sorts of discussion of practically every last molecule found in the Mount St.

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.

Their film shows an explosion of steam followed by a second explosion of boiling rocks and people running away from the explosion. The clip continues in a snowcat, where a man holds a paper towel to stanch the bleeding from his head and hugs his wife. Authorities say about 35 tourists were on the volcano when the explosion occurred around midday, and that the guides who accompanied them helped bring them to safety.

The president of the Italian Alpine Club chapter in Catania, Umberto Marino, said he was traveling up the volcano in a snowcat when injured people started running in his direction. Snow-covered Mount Etna, Europe's most active volcano, spews lava during an eruption in the early hours of Thursday, March 16, None of the injuries was listed as grave. Italy's volcanology institute said the explosion took place at about 2, meters 8, feet above sea level, putting the tourists at more than meters 1, feet below the base of the newest southeast Mount Etna crater where the lava flow originated.

Among those present when the explosion occurred was a scientist from Italy's volcanology institute, Boris Behncke, who said on his Facebook page that he had suffered a bruise to his head. The BBC crew was shaken but physically OK despite having suffered cuts, bruises and burns, she wrote.

Morelle later showed the camerawoman's jacket on the air with a big hole in the back where the material had melted in the explosion. Morelle said the explosion was "a reminder of how dangerous and unpredictable volcanoes can be.
