Radiometric dating sentences
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.

Roger C. Wiens has a PhD in Physics, with a minor in Geology. His PhD thesis was on isotope ratios in meteorites, including surface exposure dating. First edition ; revised version Radiometric dating–the process of determining the age of rocks from the decay of their radioactive elements–has been in widespread use for over half a century. There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.
A new tree-ring date for the “floating island” lava flow, Mount St. Helens, Washington
Just like a teenager wanting to be older, volcanoes can lie about their age, or at least about their activities. For kids, it might be little white lies, but volcanoes can tell big lies with big consequences. Our research , published today in Nature Communications , uncovers one such volcanic lie.
and radiocarbon methods of dating the eruption, according to new in magma under the Mount St Helens volcano before the eruption.
New analyses that use tree rings could settle the long-standing debate about when the volcano Thera erupted by resolving discrepancies between archeological and radiocarbon methods of dating the eruption, according to new University of Arizona-led research. Thera’s explosive eruption on Santorini more than 3, years ago buried the Minoan settlement on the island in a layer of ash and pumice more than feet 40 meters deep.
The effects of the eruption were felt as far away as Egypt and what is now Istanbul in Turkey. Archeologists have estimated the eruption as occurring sometime between and BC by using human artifacts such as written records from Egypt and pottery retrieved from digs. Other researchers estimated the date of the eruption to about BC using measurements of radiocarbon, sometimes called carbon, from bits of trees, grains and legumes found just below the layer of volcanic ash.
By using radiocarbon measurements from the annual rings of trees that lived at the time of the eruption, the UA-led team dates the eruption to someplace between and , a time period which overlaps with the date range from the archeological evidence. The current radiocarbon calibration curve that was developed over the past 50 years using tree rings extends 14, years into the past.
At that time, the scientists needed to use chunks of wood that combined 10 to 20 years of a tree’s annual rings to have enough wood to test for radiocarbon. Work conducted at the UA Accelerator Mass Spectrometry Laboratory contributed substantially to the radiocarbon calibration curve currently in use worldwide.
Now radiocarbon testing requires just slivers of wood, so Pearson and her colleagues could test the annual growth rings of trees from back to BC — before, during and after the time Thera was thought to have erupted. What fell out of that was that the old calibration curve wasn’t precisely correct during this time frame.
‘Ages’ obtained for the lava dome of Mt St Helens
You can see the mountain! Lloyd Anderson springs ahead of the small group of visitors he has been leading through Gifford Pinchot National Forest. Reaching a small observational clearing, he sweeps his arm toward the horizon and bounces with excitement as he waits for the group — Forest Carnine, a cattle rancher from Angora, Neb. It is one of those rare days when the weather in southwest Washington clears so you can see Mount St. Helens, which rises behind Anderson and his joyous grin.
The conventional K-Ar dating method was applied to the dacite flow from the new lava dome at Mount St. Helens, Washington.
Archaeological finds worldwide have helped researchers to fill out the story of human evolution and migration. An essential piece of information in this research is the age of the fossils and artifacts. How do scientists determine their ages? Here are more details on a few of the methods used to date objects discussed in “The Great Human Migration” Smithsonian , July :. In a cave in Oregon, archaeologists found bones, plant remains and coprolites—fossilized feces.
DNA remaining in the coprolites indicated their human origin but not their age. For that, the scientists looked to the carbon contained within the ancient dung. By definition, every atom of a given element has a specific number of protons in its nucleus. The element carbon has six protons, for example. But the number of neutrons in the nucleus can vary. These different forms of an element—called isotopes—are inherently stable or unstable. The latter are called radioactive isotopes, and over time they will decay, giving off particles neutrons or protons and energy radiation and therefore turn into another isotope or element.
Mount St. Helens
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.

In the past two months or so the dome-shaped formation of rock in the crater has been developing a large bulge, and frequent plumes of gas have been seen rising from the crater. These are clear signs of volcanic activity and they are very similar to what was seen before the eruptions of Latest reports tell of a steam plume rising passively and drifting south and south-westward over the crater rim. The plume occasionally contains minor ash, which falls in the crater and on the southern flank of the volcano, darkening the new snow.
Seismic activity remains low compared to that observed earlier, and is consistent with a slow but continuous rise of magma driving up the crater floor and feeding a surface extrusion of lava. The overall low rates of seismicity and gas emission suggest that the lava reaching the surface does not contain much gas. This is good news, since it means that highly explosive eruptions are less likely in the near future.

Mt. St. Helens Dating Methods
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.
In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze for example, Woodmorappe ; Morris HM ; Morris JD Only rarely does a creationist actually find an incorrect radiometric result Austin ; Rugg and Austin that has not already been revealed and discussed in the scientific literature.
The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.

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. The fundamental dating assumption ‘no radiogenic argon was present when the rock formed’ is questioned by these data.
