Question: Is radiometric dating, which is cited over and over as proof of evolutionary long ages, reliable? In specific, how about Potassium-Argon dating? Answer: A straight forward reading of the Bible from creation to the apostles does not allow for the earth to be millions, much less billions, of years old. Many fanciful dating methods have been used to date objects including rocks. A popular one that regularly gives dating in the multi-million year age range is Potassium-Argon dating. Without getting too technical, a quick look at one great observable example should suffice to show that the numbers given can be erratically excessive. Our example: Mount St. When Mount St. Helens blew it’s top in it transformed the surrounding terrain dramatically in a short period of time providing many other evidences as well of rapid changes reminiscent of things attributed to evolutionary change over vast periods. The lava that was spewed from this volcanic event was dated twenty years after the fact, using Potassium-Argon dating.

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.
Radiometric Dating: Doesn’t it Show that the Earth is 4.5 Billion Years Old?
Radiometric dating involves dating rocks or other objects by measuring the extent to which different radioactive isotopes or nuclei have decayed. Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy. The time that it takes for half of a sample to decay is known as the half life of the isotope. Some isotopes have half lives longer than the present age of the universe , but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.
then ineffectively separated the sample into several mineral and glass ‘fractions’, submitted the dacite and its ‘fractions’ for potassium argon 40 (K-Ar) dating.
The belief that radiodating methods give absolute measurements of time is widespread as a result of scientific popularization in journals, conferences, and the media. In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration. This calibration supposes a great number of basic assumptions concerning initial conditions. The choice of these initial conditions affects the results.
These assumptions are not demonstrated, only supposed to be true. The discussion of some phenomena taking place during rock crystallization reveals huge discrepancies between the model theory and the reality. This excess argon greatly alters the calculated age and puts into question the validity of the method. These investigations suppose complete coordination between different disciplines and laboratories.
The experimental method can solve scientific questions and problems by using instruments, measurement procedures, and data treatment. The results, taking into account previous knowledge and discussion with other specialists, help to give an interpretation or build a theory. Experiments and measurements need to be accurate, explainable and reproducible. Figure 1 shows the complex intellectual process using previous knowledge and experiments to arrive at a conclusion or hypothesis.
The most important point of the procedure consists in the discussion and confrontation with other possible explanations.
POTASSIUM ARGON DATING ERRONEOUS ON OBSERVED EVENTS
Mount Sidley is a complex, polygenetic stratovolcano composed primarily of phonolitic and trachytic lavas and subordinate pyroclastic lithologies at the southern extremity of the Executive Committee Range, a linear chain of volcanoes in central Marie Byrd Land, Antarctica. This was followed 4. The final phase of activity was the eruption of basanite cones at approximately 4. The southward migration of volcanic activity was accompanied by distinct changes in magma composition and is best explained by the sequential release of magmas stored within an intricate system of conduits and chambers in the crust by tectonically driven magma assisted?
The radioactive dating controversy of a fossil known as Skull KNM-ER is well-documented. The radioisotope methods used for rocks, potassium-argon (K-Ar), Lava from the Mt. Rangitoto eruption which happened years ago has Lava from a Mount St. Helens lava dome has just been dated at +/-
An infamous dating techniques. Used at washington erupted with science. Many fanciful dating methods rely on the same rock dating techniques. K-Ar dating methods estimate the sample from mount st.

Results on may, yes, above slid off the new lava dome at the lava dome that both thick and missing rings in which analyzes.
Mount Mazama and Archaeological Dating
Probably because I taught programming, it always bothers me when such automation remains unfinished. Nesting arises in so many applications and in an ideal world should always be addressed. As always, we should be thankful for what we have. I think you missed a very important point in this article: YEC geologist Austin did not perform the decontamination work required to get a clean sample.
6 Potassium/Argon Dating. Results on dacite collected in at the extrusion dome of Mt St Helens (Washington, USA) from eruptions.
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. The oldest, most famous national park in the United States sits squarely atop one of the biggest volcanoes on Earth. Doane was wrong, however, in one crucial respect. Yellowstone’s volcano is not extinct.
Many creationists believe the earth was created by almighty God some thousands of years ago. Evolutionists, on the other hand, maintain that the earth is about 4. How can there be such a vast discrepancy between these dates? Many Christians find this a real problem for they think that the evolutionary scientists cannot possibly be wrong.
But they can.
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. One percent of that residual air is argon. Therefore, when one measures the argon expelled by the heated sample, one also measures some argon that was already in the chamber to begin with. This is a very small amount of argon, to be sure, but when one is dealing with small samples and an isotope whose half life is over a billion years, a small amount can give a significantly false reading with older samples, the amount of argon in the vacuum chamber at the start is swamped by the amount released by the sample.
So the make the analogy accurate, Juby’s rant should have been trying to measure the water added to a glass already half full of water. Obviously, if you add a drop or two, you won’t be able to tell whether you added nothing or several drops; if you add a liter or two, the water already in the glass won’t make much difference except that the glass will overflow, so start by emptying the half-full glass into an empty gallon jug.
This exact problem does not carry over into other forms of radiometric dating, though other methods have their own limitations. There are of course methods that are appropriate for measuring the ages of much younger things radiocarbon dating, for example, is usually useful only up to ages of ca. Isochron dating — basically, comparison of multiple parent-daughter isotope pairs with parent isotopes of different decay rates — can serve as a check on possibilities ranging from the initial presence of some of the daughter isotope to changes in decay rates what is going to change multiple decay rates by the exact same fraction?
Volcanic history of Mount Sidley, a major alkaline volcano in Marie Byrd Land, Antarctica
However, it did not start this way. It was once the top of Mount Mazama, a supervolcano in the Cascade Range that towered over 12, feet above sea level. The transition from enormous mountain to the caldera it is today was explosive: about 7, years ago Mount Mazama erupted, emptying twelve cubic miles of lava and enormous amounts of pumice out of its magma chamber in mere days, during an eruption forty times as powerful as the eruption of Mount St.
The magma chamber then collapsed in on itself, forming the caldera, which filled to form Crater Lake.
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.
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.
If these dates are correct, this calls the Biblical account of a recent creation of life into question. After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.
I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions.
