Mount Mazama and Archaeological Dating

Members Portal. Young Earthers point to an infamous dating error as evidence that the Earth is only as old as the Bible says. Skeptoid Podcast March 24, Podcast transcript Subscribe. 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.

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.

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. To conclude that no geologist can perform the decontamination work is therefore entirely without warrant.

Henke criticizes Austin precisely because Austin failed to adequately use known techniques for decontaminating samples. Moreover, the contamination—to the extent it created any problem—may have added a couple million years to the Mt. Helens samples. This would scarcely be a rounding error for the strata used to date the dinosaur fossils Mary Schweitzer analyzed.

I appreciate that you are eager to amass evidence for very young life on earth, and you do so for honorable motives. In my opinion, though, the best way to honor the God of truth is to look carefully before we leap to conclusions that In any endeavor, whether theological or scientific or both, in this case , it is wise to consult with others who have expertise in the field s you are exploring.

I very much have the sense that you have not discussed your ideas about geological evidence with Ph.

Excess Argon within Mineral Concentrates from the New Dacite Lava Dome at Mount St. Helens Volcano

Although there are currently no active volcanoes in New Mexico, many extinct volcanoes are preserved in the state. Lava flows near Grants and Carrizozo are the youngest volcanic flows in the state about years old and years old, respectively. Shiprock is usually referred to as a special volcanic landform called a volcanic neck , which is the solidified feeder system of a volcano.

Steve Semken suggests that lava that makes up Shiprock interacted explosively with groundwater, forming a diatreme.

Briefly, Steve Austin collected a sample from the Mount St. Helens Also, how can this only be a problem with potassium/argon dating and not.

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.

Radiometric dating

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?

6 Potassium/Argon Dating. Results on dacite collected in at the extrusion dome of Mt St Helens (Washington, USA) from eruptions.

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. The rubidium-strontium and uranium-lead techniques are very difficult to use with such samples, because the slow decay rates of the parent isotopes have not allowed a significant increase in the daughter isotopes.

Commonly the ages of minerals from rather old rocks dated by the potassium-argon method are lower than the ages obtained by either the rubidium-strontium and uranium-lead dating. Moreover, many studies have demonstrated that argon escapes readily during metamorphic events when rocks become heated and partially crystallized. Dr Steven A. This sample had not been exposed to the argon in the air over the 10 years since it was formed. Mineral Sample 40 K. Therefore any 40 Ar measured was not radiogenic argon.

Showing Their Age

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,.

Dr. David Plaisted has written a “critique” of radiometric dating, which appears In his Mt. St. Helen’s study, Austin collected what he thought was a freshly Potassium-argon dates and the Cenozoic Mammalian Chronology of North America.

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. Various elements are used for dating different time periods; ones with relatively short half-lives like carbon or 14 C are useful for dating once-living objects since they include atmospheric carbon from when they were alive from about ten to fifty thousand years old.

See Carbon dating. Longer-lived isotopes provide dating information for much older times.

‘Ages’ obtained for the lava dome of Mt St Helens

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.

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. During this explosion, Mount Mazama also erupted an enormous ash plume. This is where archaeology ties in. The ash cloud was so immense that it stretched over nearly the entire northwest, as far north as Alberta, Canada. This ash layer, which soon cooled to a solid, remains an easily visible lighter layer of sediment throughout this whole area, providing archaeologists studying much of the Pacific Northwest with a definitive time stamp for relative dating.
