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 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. First, it provides no evidence whatsoever to support their claim that the earth is very young.

Many people are under the false impression that carbon dating proves that dinosaurs and other extinct animals lived millions of years ago. What many do not realize is that carbon dating is not used to date dinosaurs. Carbon dating is only accurate back a few thousand years. So if scientists believe that a creature lived millions of years ago, then they would need to date it another way. But there is the problem. They assume dinosaurs lived millions of years ago instead of thousands of years ago like the bible says.
They ignore evidence that does not fit their preconceived notion. What would happen if a dinosaur bone were carbon dated?

Modern methods can detect essentially any Carbon , and therefore produce dates up to about , years. Methods A sample is taken and prepared by removing any extraneous material, and removing any inclusions from the sample. The sample is then crushed and dissolved.

But there is the problem. They assume dinosaurs lived millions of years ago instead of thousands of years ago like the bible says. They ignore evidence that does not fit their preconceived notion. What would happen if a dinosaur bone were carbon dated? The age they came back with was only a few thousand years old. This date did not fit the preconceived notion that dinosaurs lived millions of years ago.
So what did they do? They threw the results out. And kept their theory that dinosaurs lived “millions of years ago” instead. This is common practice.
10 Oldest National Parks in the World
Posted by Sam Patterson on October 11, Although seemingly insignificant in themselves, the anomalous K-Ar “model ages” for these recent andesite flows at Mt Ngauruhoe, New Zealand, lead to deeper questions. From where did it come? Answers to these questions in turn point to significant implications that totally undermine such radioactive “dating” and that are instead compatible with a young Earth. It shows how there was excess Argon in some andesite flows.
Mar 28, · Mount Ngauruhoe, North Island, New Zealand (Mount Doom!) Mount Ngauruhoe, North Island, New Zealand (Mount Doom!). Visit Radiometric Dating on Trial: How Reliable Is It? There are many techniques and lines of evidence for dating the age of the earth and of rocks and fossils.
Zircons found from grains in Western Australia are considered slightly older – 4. Geologists depend on radiometric age dating to give dates to different strata and the rocks and bones and artifacts found in those layers. Most will say that the dating methods have been confirmed over and over again, but there are questions about whether the dating methods used are reliable and whether they give scientists true dates – or whether they give dates that fit those secular geologists’ preconceived ideas.
During its history, the earth has suffered constant change. Erosion, volcanic eruptions, earthquakes, catastrophes change the surface of the earth, melting rocks, grinding them up and spitting them back out in different forms than they had when they started. Those who trust in radiometric dating methods point to G. Brent Dalrymple’s book The Age of the Earth, in which he lists the ages of various chondrite samples age-dated through several methods.
Samarium-neodymium Sm-Nd dating of chondrites gives a date of 4. Dalrymple lists other sets of samples and shows that the samples consistently date between 4. This looks like convincing evidence that the earth is truly about 4. Dalrymple’s results appear to be fairly consistent in giving the earth an age of well over 4 billion years. As we noted last week, however, the use of these dating methods depends on a number of assumptions.
When these methods give dates hundreds of millions of years apart, even without taking the margins of error into consideration, we can reasonably hesitate to put our full faith in them. Despite claims to the contrary, dating methods do not always give consistent dates, and can give widely different results for samples of rocks from the same layers.

Recent activity[ edit ] Ngauruhoe erupted 45 times in the 20th century, most recently in Climbers who suffer from asthma may be affected by the strong sulphurous gases emitted from the crater. Aerial photo of crater Ngauruhoe is no longer showing signs of any significant unrest and the Volcanic Alert Level has been reduced to zero typical background activity. A significant increase in earthquake activity in May prompted the alert level to be raised to one signs of volcano unrest.
Over the next two years GeoNet recorded an average of 5 to 30 earthquakes a day close to Ngauruhoe, though the maximum daily number was as high as Since mid the number of volcanic earthquakes close to Ngauruhoe has declined to the background level.

Putangirua Pinnacles — aka Path of the Dead Credit: Filming at the summit was not permitted because the peak is sacred in Maori culture; however, some scenes were filmed on its lower slopes. The drama can be reimagined on the hiking trails, starting from Tongariro’s visitor centre.

Fisher  investigated submarine basalt from a Pacific seamount and found “the largest amounts of excess 4He and 40Ar ever recorded” at that time. He then produced concentrates of the constituent minerals, which yielded anomalous K-Ar model “ages” of 0. Furthermore, the whole-rock “age” is very similar to the “age” of the plagioclase concentrate because plagioclase is the dominant constituent of the dacite.
Aug 10, · Carbon dating makes an animal living 4 thousand years ago (when there was less atmospheric carbon) appear to have lived thousands of years before it actually did. What was the original amount of Carbon in the atmosphere? Lava flows at Mt Ngauruhoe.
Potassium to Argon Dating 1. It is assumed molten rock contains no argon gas, because gas escapes from the liquid rock. When the rock cools and turns solid some of the unstable 40K decays into 40Ar. Mass spectrometry, or atomic absorption spectroscopy is used to measure captured 40Ar. Potassium-Argon dating can only be used to calculate ages of igneous rocks rock that used to be magma. It does not work on sedimentary layers because they are composed largely of smaller particles of other rock layers.
Samples from the dacite flow on Mount St. Helens, Washington, were K-Ar tested to a date of , years old! Ngauruhoe erupted several times in the past years, and several of these samples have been K-Ar dated to ages of , — 3, , years old! Molten zircon strongly rejects lead but allows uranium to mix. It is assumed that molten zircon contains no lead. When the rock solidifies the U decays into Pb through several steps releasing helium.
The amount of lead is measured and the age is calculated. Uranium-Lead dating can only be used to date igneous or metamorphic rock.
