- Geologists have known about this problem since the K-Ar method was first put forth, and McDougall et al.
- Keep thinking about starlight, which traveling at the speed of light, took millions of years to get here.
- After all, to say that the lab did not contaminate the specimen proves nothing.
We have a very clear bias and we found that on our understanding of the Bible and its authority. Results seemed to show that Rangitoto was not a few hundred years old as it appeared to be. That brings me to my next point. Only human arrogance would insist on limiting God, an infinite being, to a finite hour day.
We have supplied this link to an article on an external website in good faith. It means the geologist has to do the best he can with the tools available to date the objects. Of course, the best method is to check the account of a reliable eyewitness, if one is available. Most geologists understand the dating techniques, and accept their limitations.
Please let me know if I ever fail to align my thoughts with His Word. This means radiogenic argon had been accumulating in those rocks for hundreds of thousands, if not millions of years before it was incorporated into the erupting basalts. This lava is made of various elements. Typically, one assumes that no argon or negligible amounts thereof was initially present, because argon is a noble gas and can easily diffuse out of minerals that are still hot. The data is interpreted to produce dates.
- On the other hand, while I disagree with the scientific conclusions of Mr.
- Can we rely on radiometric dating techniques?
- Coal is used next as an example.
- Doolan provides a convincing case against the credibility of K-Ar dating.
- Robert Doolan of Answers in Genesis concluded that the K-Ar method is not a valid option in response to the above question.
- However, the basic argument is the same, as you noted.
Please read my guidelines and background posts before proceeding! It measures the amounts of certain radioactive substances. So if scientists wanted to measure the age of a fossil using this method, they would look for a nearby layer of igneous rock e. Wow, there goes another million years! Stratigraphy alone implies an old earth.
Introduction to the controversy Over the years, Answers in Genesis has committed to undermining the credibility of radiometric dating techniques. But if the failure of the K-Ar dating method is so obvious, why do scientists still spend so much money on running samples? My hope is to convince you this is the case through the following example, and that AiG had prematurely discredited the K-Ar dating method. First, all radiometric dating methods are scientific models used to estimate the age of geologic events, provided a number of physical assumptions regarding the rock's history are met. The next section is Other Radiometric Dating Methods.
Questioning Answers In Genesis Has Answers in Genesis debunked K-Ar dating
Because although not perfect, it is the best tool we have. Okay, we are both guilty of assumptions. Keep considering the rock layers, which can't be laid down in a global flood. The authors found the method to be unreliable in isolation, meaning fwb but readily explained the discordant ages using thorough petrographic and geochemical analyses.
Actually, any process used to find ages for things is based on assumptions, and so is not reliable. Sure, they exist, dating ex again but are probably in the minority. How do you date a New Zealand volcano?
When they find one, they gather a sample of the hardened lava and send it off to a laboratory to test it for radioactive elements. As you can imagine, the chaos of Earth systems can produce both scenarios, so geochronologists have developed techniques to verify test each assumption. If there are possible discrepancies, how can I accept these dates as reliable? Xenolithic quartz was also found, indicating that the melt had incorporated foreign material during its assent.
However, even if we measured how much of A and B were in a sample of rock, could we figure out how long A has been changing into B, and therefore how old the rock is? In other words, this study confirms the use of K-Ar isochrons in older volcanic rocks since the true age would be within the uncertainty range of your model age. In fact, most fossils do not even contain radioactive minerals.
As a result, more recent articles will reflect the current thinking. The purified groundmass from this lava resulted in an age spectrum in which all but the highest temperature steps y ielded a zero age owing to negligible quantities of radiogenic argon. He dated meteorites, not earth rocks. They determined that according to the K-Ar method, the age of the volcano was indistinguishable from zero i. Contamination can often be accounted for, along with the loss of argon.
Dates do not come from the isotope ratios directly. Of course, I'm interested to address the more recent articles you mentioned at some point, but I thought this was a good place to start esp. Radiometric dating techniques were rudimentary, in that they required large samples and a steady hand. To us, this means be careful when dating lava! Using the uniformitarian assumptions, dates are calculated using various models.

This is an excellent example. This argon is potentially captured in the crystal structure of forming minerals, which would give it an anomalously old date. In this sense, it is much like estimating the origin of a cannonball in flight, using a set of physical observations and the laws of gravity.
The next section is Testing Radiometric Dating Methods. The Bible is such a record. The author gives a very good description of Carbon, except the flood part.
Overall, I only wish to encourage consistency in scientific arguments, especially when those arguments are aimed at more pertinent matters than historical geology. What we have to decide this issue is the evidence from God's creation, and not our assumptions. Feel free to check out more of this website. Geologists know that the dates are not perfect, that's why you will see research articles trying to determine the age of a rock, and there will be ten, twenty, or more samples that were dated. Okay, ost marriage not dating stop on with the article.
Have you ever wondered how the scientists knew the age of the bone? As you might expect, it is never that simple. In fact, I don't mind if you ignore all Carbon evidence. As you should know, the models that AiG uses change as we recognize their shortcomings and new data comes to light. Are we going to have clocks in heaven?
Creation Science Rebuttals
It is fairly concise, but in depth. Newer Post Older Post Home. My advisor once scolded me for calling chemostratigaphy a relatively recent discipline.
Only then will I know for certain. While the magma rises to the surface, it heats up the surrounding rock and argon is transferred to the melt. For any given rock, each kind of mineral will yield a different age, depending on how quickly the rock cooled.
Release of excess argon at high temperatures suggests the presence of contaminants within the mineral, and explains the anomalously old ages obtained by earlier studies. Remember, context, context, context. Nowhere in the Bible does it state that the days of creation are hour days. To test this method, some scientists gathered samples from hardened lava at Mount St Helens, which erupted most recently in the early s. Since it is the written Word of God, we can trust it to tell us the truth about the past.
How Carbon Dating Works
Such technology has been used in recent years to confirm early suspicions of geologists that tried to interpret discordant dates. The rest of the article is interesting, but not critical. You have an interesting perspective on history. When the cow dies, it stops taking in carbon for obvious reasons. So now that you are better prepared, let's continue!
The second reason is more profound, but before I elucidate, I would conclude that Mr. Concluding remarks In this particular article, I think it is clear that Mr. Anyone with access to a university library system can check whether this is true, megamates www but most AiG readers and I don't blame them wouldn't care to take the time to find a year old journal article.
