Is Mount St Helens a case of radioisotope dating failure?

Originally published in Creation 23, no 3 (June 2001): 24. Is this dating failure from Mount St Helens an isolated case of radioisotope dating giving wrong results for rocks of known age? Certainly not!

How did the discovery of Mount St Helens change the world?

It also showed that radiometric dating is not necessarily accurate and that God gave animals and plants the ability to rapidly re-colonize barren land. And the improved seismic prediction techniques that Mount St. Helens facilitated have also increased scientific understanding of earths geologic activities.

What did Mount St Helens teach us about coal deposits?

And in a strange but profound way, Mount St. Helens offered a significant new interpretation of coal deposits. Many logs were transported by the blast to nearby Spirit Lake. As they jostled and shifted in the water, the bark rubbed off and sank to the bottom of the lake to form a sheet of waterlogged bark.

Is there enough argon in solidified samples for dating?

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

Is there such a thing as wrong radioactive dating?

Dalrymple, 1 one of the big names in radioactive dating [and a self-confessed intermediate between an atheist and agnostic], lists a number of cases of wrong potassium-argon ages for historic lava flows (Table A). There are many other examples of obviously wrong dates.

What was the impact of Mount St Helens in 1980?

On May 18, 1980, 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.

What did Mount St Helens teach us about coal deposits?

And in a strange but profound way, Mount St. Helens offered a significant new interpretation of coal deposits. Many logs were transported by the blast to nearby Spirit Lake. As they jostled and shifted in the water, the bark rubbed off and sank to the bottom of the lake to form a sheet of waterlogged bark.

Is radiometric dating reliable?

The results came back dating the rock to 350,000 years old, with certain compounds within it as old as 2.8 million years. Dr. Austins conclusion is that radiometric dating is uselessly unreliable.

What is the potassium-argon method of rock dating?

One of the most widely used dating methods is the potassium-argon method, which has been applied to ‘dating’ rocks for decades, especially igneous rocks that have solidified from molten magma. The attraction of the method lies in the fact that one of the daughter elements is argon which is an inert gas.

How is argon-argon dating done?

Argon-argon dating gets around many of the issues by measuring only multiple isotopes of argon. The trick is to irradiate the sample with neutrons along with samples of known age. Some of the potassium-39 forms argon-39 by an n,p reaction.

What is the advantage of 39 AR for potassium dating?

Because 39 Ar has a very short half-life, it is guaranteed to be absent in the sample beforehand, so its a clear indicator of the potassium content. The advantage is that all the information needed for dating the sample comes from the same argon measurement.

What is the physical procedure for 40 AR-39 Ar dating?

The physical procedure for 40 Ar- 39 Ar dating is the same except for three differences: Before the mineral sample is put in the vacuum oven, it is irradiated along with samples of standard materials by a neutron source. There is no 38 Ar spike needed.
