Excess Argon within Mineral Concentrates from the New Dacite Lava Dome at Mount St. Helens Volcano
All rights reserved. Update: Our new Yellowstone National Park stories may surprise you with pictures of Yellowstone’s remarkable animals. On August 29, , a year-old Army lieutenant named Gustavus Doane, part of an exploratory expedition in the Yellowstone region in the territory of Wyoming, scrambled his way to the summit of Mount Washburn above the Yellowstone River. Looking to the south, he noticed that something was missing from a stretch of the Rocky Mountains: mountains. For miles and miles, the only elevations were in the distance, forming parentheses around a huge forested basin. Doane saw only one way to explain the void. The lieutenant was right: Yellowstone is a volcano, and not just any volcano.

Radiometric dating is the measurement of the remaining amount of an unstable element, a radioactive isotope Potassium-argon dating of lava from Mount St. Helens “Mt Ngauruhoe, central North Island, New Zealand.

How Accurate is K-Ar Dating? Email: laurence unmaskingevolution. Webpage: www. Messel, “A Modern Introduction to Physics” vol. The radiogenic argon that builds up in potassium-rich minerals after they have crystallized, therefore, furnishes a good measure of the age of the sample.
Some updates to this article are now available. The sections on the branching ratio and dating meteorites need updating. Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.
We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.
Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate. However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.
Radiometric Dating: Doesn’t it Show that the Earth is 4.5 Billion Years Old?
Isotopes are atoms of the same element which vary by the number of neutrons in their nucleus. Some isotopes have so many neutrons that the nucleus is unstable and reduces its size by releasing either alpha or beta particles or gamma rays. In such situations, the isotope is termed radioactive. Radioactive elements are ubiquitous in soil, water and air. Each radioactive element has its own rate of decay, which has been established in laboratories.
So this method can be used to date volcanic rocks, such as the dacite lava dome on Mount St Helens. Potassium-argon dating works like this: Potassium (an.
A big problem for evolution is that it has never been observed, which is quite devastating since observations are vital for science. No one has ever witnessed one kind of animal in the process of changing into a totally different kind. Their answer for this is that evolution happens so slowly that no one can see it happening. Still, some sort of active transitioning should be visible today.
But not only that, there should be an abundance of evidence for this change in the fossil record. Unfortunately, the missing link is still missing,. If evolution were true, there would be billions of fossilized, transitional intermediate forms of one kind of animal changing into another. About years have passed. There are about million fossils in museums around the world. Evolution cannot correctly date the earth. In the early s, a volcano erupted on Mount St. But when these rocks were dated early in the year of , they were dated as high as 2.
The decay product measured, when doing potassium-argon K-Ar dating is argon This is the same isotope argon that is produced by the decay of potassium the radioactive isotope in contrast to, e. The vacuum chamber does not contain a perfect vacuum; a tiny amount of residual air remains.
The dating method Dr Austin used at Mount St Helens was the potassium-argon method, which is widely used in geological circles. It is based.
Anomalies of Radiometric Dating Logic and science dictates that if something which is assumed to have a uniform rate is shown in a single example to not be uniform, the theory must be abandoned as unreliable. The previous section showed that it is entirely possible for the uniform rates of radiometric dating to be very easily changed through enviromental conditions most have been documented by secular scientists. This section will provide 19 specific examples of this decay-rate-change having occured.
Rock from a dactite lava dome at Mount St. Helens that was formed in during the eruption there was dated using the Potassium-Argon [K-Ar] method at 0. A British Engineer, Sidney P. Clementson, studied a variety of modern volcanic rock.
How Old Is the Mount St. Helens Lava Dome?
Because radiometric dating utterly refutes their biblical interpretations, young-Earth creationists YECs are desperate to undermine the reality of these methods. As part of their efforts, YEC Dr. Austin et al.
At Mount St. Helens, the potassium-argon dating method incorrectly indicates that certain minerals hardened into stone , years ago, when in reality they.
Copyright by Creation Science Foundation, Ltd. All Rights Reserved. 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 0. Mineral concentrates from the dacite which formed in give K-Ar ‘ages’ from 0.
These ‘ages’ are, of course, preposterous.
