Most people assume that scientists really know how old the rocks are. The truth is, they don’t. The more you study about the various methods for determining the age of the rocks, the more you will realize how unreliable those methods are. The accuracy of these dates is important because they are used to establish the theory of evolution. If these dates are wrong, then the theory of evolution is wrong. This skull, very modern in appearance, was found in a layer of rock that was believed to be too old to contain a modern skull.
Carbon dating can not be much use to them since it is inaccurate beyond a few thousand years and is easily polluted, but radiometric dating seems to hold better promise. While it is true that radioactive elements decay at a predictable rate, one simply CAN NOT KNOW whether the “daughter” elements present in a rock sample were present during formation or are merely the result of the decay process. In other words, how do we know whether or not a sample had ONLY parent materials when it formed.
If the samples are not in a perfect ratio, it is fair to dismiss any age proposed by this method on that sample. This does NOT mean, though, that one can dismiss the idea of God creating the sample that way, so like it or not, we are still left with a choice which will be determined by our philosophical bias.
Claim CD The conventional K-Ar dating method was applied to the dacite flow from the new lava dome at Mount St. Helens, Washington. The whole-rock age was +/- million years (Mya).
However, rather than dealing with this issue and critically evaluating Austin’s other procedures including the unacceptable mineral and glass impurities in his ‘fractions’ , YECs loudly proclaim that the results are discrepant with the AD eruption. They then proceed to assault the validity of the K-Ar method. Therefore, it’s not surprising that some of Austin’s dates, such as the result for the amphiboles, etc.
Without properly referencing Bartelt et al. Obviously, Swenson, like many YECs, fails to realize that scientists can successfully unravel past events without witnessing them. Forensic scientists frequently send criminals to prison without eyewitness testimony. To be exact, the recent hideous actions of the Washington DC area USA sniper s illustrate how unreliable eyewitnesses can be and how important forensic science is in solving crimes and stopping killers.
In contrast to Austin et al. Circular Reasoning or Reliable Tools?
Mount St. Helens
Wikimedia 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. 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.
September 6, Helens foreground is so out of line with other young, active volcanoes in the Cascades range, such as Mount Rainier background. An ancient scar from past tectonic collisions sits under Mount St. Helens and may act as a conduit for deeply-buried magma. Helens is out of line. The volcano, part of the Cascades range in Washington state, sits about 40 miles 64 kilometers west of other young volcanoes in the region, like Mount Adams and Mount Rainier.
Now, researchers have figured out why: Deep in the Earth’s crust , a plug of cooled igneous, or volcanic, rock keeps magma from surfacing between Mount St. Helens and the rest of the volcanic arc. Meanwhile, the crust under the Mount St. Helens consists of an ancient scar caused by two continental plates slamming together. The scar is “almost like a soda straw, which is allowing these deeper magmas to preferentially ascend to the surface,” said Paul Bedrosian, a geophysicist at the U.
Helens is weird not just because of its westerly location, but also because it erupts thicker, stickier magmas than other Cascades volcanoes and because it’s the most restless mountain of the bunch, Bedrosian told Live Science.

The conventional K-Ar dating method was applied to the dacite flow from the new lava dome at Mount St. Helens, Washington. Porphyritic dacite which solidified on the surface of the lava dome in gives a whole rock K-Ar ‘age’ of ± million years (Ma).

Helens Really a Million Years Old? The best “proof” for millions of years of earth history in most people’s minds is radioisotope dating. But is the method all it’s cracked up to be?
These dating methods rely on a series of assumptions about the amounts of the parent-daughter elements, and a constant rate of decay. This is a real and common problem with radiometric dating techniques. Consider also: Mt. Etna – erupted years ago, but rocks were dated 25 million years ago. Mount St. Helens erupted in
This belief in long ages for the earth and the existence of life is derived largely from radiometric dating. These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio. This age is computed under the assumption that the parent substance say, uranium gradually decays to the daughter substance say, lead , so the higher the ratio of lead to uranium, the older the rock must be.
Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning. Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava.
Lava properly called magma before it erupts fills large underground chambers called magma chambers. Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios. Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger.
This calls the whole radiometric dating scheme into serious question. Geologists assert that older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older.

Radiometric Dating Does Work! Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds for example, Arndts and Overn ; Gill but such attempts invariably have fatal flaws see Dalrymple ; York and Dalrymple Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.
For example, when the fresh lava dome at Mount St. Helens was only ten years old, it showed a radioisotope age estimate of , years! 2 Many such examples cast doubt on the entire dating method.

Now, researchers have found that the scars of ancient crustal collisions explain the volcano’s position. Esteban Bowles-Martinez Researchers from the U. Geological Survey, Oregon State University and the University of Canterbury used a method called magnetotellurics to measure the electrical conductivity of rocks deep below the Earth’s surface.

Helens, located in southwestern Washington about 50 miles northeast of Portland, Oregon, is one of several lofty volcanic peaks that dominate the Cascade Range of the Pacific Northwest; the range extends from Mount Garibaldi in British Columbia, Canada, to Lassen Peak in northern California. Geologists call Mount St. Helens a composite volcano or stratovolcano , a term for steepsided, often symmetrical cones constructed of alternating layers of lava flows, ash, and other volcanic debris.
Composite volcanoes tend to erupt explosively and pose considerable danger to nearby life and property. In contrast, the gently sloping shield volcanoes, such as those in Hawaii, typically erupt nonexplosively, producing fluid lavas that can flow great distances from the active vents. Although Hawaiian-type eruptions may destroy property, they rarely cause death or injury.
The dating method Dr Austin used at Mount St Helens was the potassium-argon method, which is widely used in geological circles. often millions of years. The Mount St Helens lava dome gives us the opportunity to check these assumptions, because we know it formed just a .
K-Ar dates of dacite from Mount St. Helens are very old Talk. Origins From CreationWiki, the encyclopedia of creation science Jump to: Origins is a response to a rebuttal of a creationist claim published by Talk. Origins Archive under the title Index to Creationist Claims. The conventional K-Ar dating method was applied to the dacite flow from the new lava dome at Mount St.
The whole-rock age was 0. Ages for component minerals varied from 0. These ages show that the K-Ar method is invalid.
