He assumes the coal beds were all laid down during the Flood, but I have already disproved that theory read here. Radiometric dating is not a simple topic. Before moving on, I must clarify one thing.
Robert Doolan of Answers in Genesis concluded that the K-Ar method is not a valid option in response to the above question. Introduction to the controversy Over the years, Answers in Genesis has committed to undermining the credibility of radiometric dating techniques. To us, this means be careful when dating lava!
- Have you ever wondered how the scientists knew the age of the bone?
- 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.
- This is an excellent example.
- Can we rely on radiometric dating techniques?
- Are we going to have clocks in heaven?
- We have a very clear bias and we found that on our understanding of the Bible and its authority.
- How do you date a New Zealand volcano?
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. 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. 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.
How Carbon Dating Works
That, of course, is a caricature. So did the original authors warn others to reject the K-Ar method and that it could never give us insight to the true age of rocks? Please read my guidelines and background posts before proceeding! This means radiogenic argon had been accumulating in those rocks for hundreds of thousands, speed dating o2l if not millions of years before it was incorporated into the erupting basalts.
The problems is
Questioning Answers In Genesis Has Answers in Genesis debunked K-Ar dating
The next section is Testing Radiometric Dating Methods. The next section is Other Radiometric Dating Methods. 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, dating or more samples that were dated.
My advisor once scolded me for calling chemostratigaphy a relatively recent discipline. Actually, any process used to find ages for things is based on assumptions, and so is not reliable. As you might expect, it is never that simple. Contamination can often be accounted for, along with the loss of argon.
The first reason is that the amount of initial Argon, while detectable, is very very small. Lastly, this is not the first time I've been called out for using ambiguous time-terms regarding the history of science. We have supplied this link to an article on an external website in good faith. To their credit, they have remained prolific, and optimistic about their findings, despite widespread ridicule from academia and the general public. Even the article we are directing you to could, in principle, speed start change without notice on sites we do not control.
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. These generate data that must be interpreted to arrive at a date. 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. 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. One example would come from my book, the fourth chapter is available on the AiG page today and deals with that very topic.
Creation Science Rebuttals
In fact, most fossils do not even contain radioactive minerals. Other scientists collected samples from cooled lava flows from Mt Ngauruhoe, in New Zealand. So now that you are better prepared, let's continue! As you should know, the models that AiG uses change as we recognize their shortcomings and new data comes to light. It is fairly concise, wrestling but in depth.
Sure, they exist, but are probably in the minority. Okay, we are both guilty of assumptions. Keep considering the rock layers, which can't be laid down in a global flood. This argon is potentially captured in the crystal structure of forming minerals, which would give it an anomalously old date.
But if the failure of the K-Ar dating method is so obvious, why do scientists still spend so much money on running samples? Are there scientists out there that will swear up and down that their dates are completely accurate? This lava is made of various elements. To test this method, some scientists gathered samples from hardened lava at Mount St Helens, which erupted most recently in the early s.
For any given rock, each kind of mineral will yield a different age, depending on how quickly the rock cooled. This process is obviously more important in rocks that solidify at the surface i. 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.
As documented in the McDougall paper, the excess radiogenic argon had to come partly from sedimentary rocks surrounding the magma chamber. The author gives a very good description of Carbon, except the flood part. Doolan provides a convincing case against the credibility of K-Ar dating. But whatever your passion for decaying metals and your level of chemical comprehension is now, I want to share my confidence that you can follow along just fine.
Most geologists understand the dating techniques, and accept their limitations. Radiometric dating techniques were rudimentary, in that they required large samples and a steady hand. 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.
Doolan has employed argumentation that is misleading, if not deceptive though I will grant the benefit of the doubt, and assume he is not intending to deceive anyone. Newer Post Older Post Home. Dates do not come from the isotope ratios directly.
The data is interpreted to produce dates. After all, to say that the lab did not contaminate the specimen proves nothing. As a result, more recent articles will reflect the current thinking. The authors found the method to be unreliable in isolation, but readily explained the discordant ages using thorough petrographic and geochemical analyses.
