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.
The ICR staff was made aware that our group would be visiting the museum, and they suggested an introductory lecture followed by a tour of the museum. The lecture was given by geologist Dr Steve Austin, who showed us a video which he said is also shown at the Mt St Helens visitor center. The Mt St Helens eruption was described in accurate detail, and there was a great emphasis on the velocities of the mudflows and the amounts of material that were removed and deposited elsewhere.
It was Austin’s intention to use the Mt St Helens eruption to convince us that catastrophes can cause rapid, large-scale changes on the earth’s surface.
The method used at Mount St. Helens is called potassium-argon dating. It is based on the fact that potassium (an isotope or “variety” of the element potassium) spontaneously “decays”, becoming argon (an isotope of the element argon).
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. Creation Ex Nihilo Technical Journal 10 3: Austin sent his samples to a laboratory that clearly states that their equipment cannot accurately measure samples less than two million years old. All of the measured ages but one fall well under the stated limit of accuracy, so the method applied to them is obviously inapplicable.
Since Austin misused the measurement technique, he should expect inaccurate results, but the fault is his, not the technique’s. Experimental error is a possible explanation for the older date. Austin’s samples were not homogeneous, as he himself admitted. Any xenocrysts in the samples would make the samples appear older because the xenocrysts themselves would be old.
Radio-dating in Rubble
Software About the Volcano Hazards Program The mission of the USGS Volcano Hazards Program is to enhance public safety and minimize social and economic disruption from eruptions through delivery of effective forecasts, warnings, and information of volcano hazards based on scientific understanding of volcanic processes. The USGS Volcano Hazards Program VHP monitors and studies active and potentially active volcanoes, assesses their hazards, and conducts research on how volcanoes work in order for the USGS to issue “timely warnings” of potential volcanic hazards to emergency-management professionals and the public.
Thus, in addition to collecting and interpreting the best possible scientific information, the program works to effectively communicate its scientific findings and volcanic activity alerts to authorities and the public. Volcano monitoring networks and scientific observation are basis for warnings, research, and situational awareness. Data collected by volcano-monitoring networks and extensive fieldwork surveys are indispensable; they help scientists interpret volcanic behavior, forecast eruptions, identify likely eruption impacts, and provide situational awareness — information relating to eruptions and unrest.
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.
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? Can we really trust it? The lava dome at Mount St. Helens provides a rare opportunity for putting radioisotope dating to the test. In August of , I had the exciting privilege of accompanying geologist Dr. Helens to view the lava dome. It was one of those experiences that was well worth every exhausting moment! It is composed of a volcanic rock called dacite and appears to an observer in the crater as a huge steaming mound of dark, blocky rubble.
Actually the present lava dome at Mount St. Helens is the third dome to form since the eruption, the first two having been blasted away by subsequent eruptions. The current dome started to form after the volcano’s last explosive eruption on October 17, During 17 so-called dome-building eruptions, from October 18, to October 26, , thick pasty lava oozed out of the volcanic vent much like toothpaste from a tube.
How do evolutionists explain the rapid formation of layers of the earth at Mt. St. Helens?
First Published August Mount Saint Helens has been one of the creationists main focus over the last 15 years. There are rebuttals for all of these issues, and you can check out some of them with the links at the bottom of this page. However, old earth creationists don’t need these rebuttals to show that Mount Saint Helens does not support young earth creation science. There are two sides to Geology.
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 When Mount St. Helens erupted 35 years ago, officials were ill-prepared for the magnitude of the emergency. Helens erupted 35 years ago Monday, killing 57 people and blanketing much of Central Washington in ash, officials were ill-prepared for the magnitude of the emergency. While the west side was dealing with mud and debris flows taking out bridges and roads, the prevailing winds pushed an estimated million tons of ash eastward, turning Sunday morning in Yakima into midnight.
We could have an eruption with a few days of warning; it could be years from now. Mount Adams, Mount Rainier, Mount Baker and Glacier Peak are also capable of producing destructive mud and debris flows, known as lahars, and spewing ash. Countless tons of it fell across much of the county during the eruption.
Problems from Unexplained Anomalies
Helens by Brian Thomas, M. 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. The Institute for Creation Research has studied the volcano over the past three decades, conducting research that has provided a suite of informative lessons with broad-ranging implications.
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).
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.
But even if it is true that older radiometric dates are found lower down in the geologic column, which is open to question, this can potentially be explained by processes occurring in magma chambers which cause the lava erupting earlier to appear older than the lava erupting later.
Earth’s Ancient Scars Explain Strangeness of Mount St. Helens
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
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 .
On average, we locate 4 to 14 earthquakes within 10 km of the volcano each week. Helens and the nearby St. Helens Seismic Zone occasionally produce swarms of many small earthquakes, but these are not usually directly associated with magmatic activity. An additional challenge on Mount St. Helens is that small rockfalls commonly occur on the steep crater rim. For lots of detail on the past seismicity at Mount St.
Helens see the seismicity page. Seismicity Seismicity at Mount St. Helens is quite variable depending on the volcano’s eruptive state. Most earthquakes are located at a shallow depth directly under the volcano; however there is a St. Helens Seismic Zone SHZ that extends north and south of the volcano on which some earthquakes take place. Seismicity changes character just before eruptions begin.
There is usually an increase in both number and size of earthquakes as well as a change in the character of the seismograms.
Mount St. Helens
The Radiometric Dating Game 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.
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.
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.
