Could the argon they measured have come from a source other than radioactive potassium decay? They then sent it to a laboratory run by the University of Arizona, where radiocarbon dating could be carried out. The mountain chain grew due to these processes and eroded due to other processes and so the whale fossils on the Andes come from the ocean originally. Bucha, who has been able to determine, using samples of baked clay from archeological sites, what the intensity of the earth's magnetic field was at the time in question. If you find 50 grams, the sample must be about 250 years old.

Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years. For example, for Carbon-14, it would take 5730 years for the 50% of the initial remaining to turn up to lose its capability in radioactive decay in order to have 50% of what has remained after the initial remaining to activate radioactive dating. This is the same as the initial amount it would not change if there were no parent isotope to decay. In other words, there was more initial argon than might be expected from a purely atmospheric source. Because Swenson does not provide a page number for his citation of Dalrymple 1969 , the identity of the volcanic glass with excess argon is uncertain. It is not about philosophical issues regarding conscience or morality. In any event, it is important to keep these anomalies in perspective.

. Eventually, all the radioactive nuclei in the mountain will decay. So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. And the result of this accepted method dates dinosaur fossils to around 68 million years old. Question: But don't trees sometimes produce more than one growth ring per year? Indeed, there is no known physical phenomenon that can yield consistent results in many thousands of measurements, year after year, except one: that these specimens really are as old as the data shows them to be.

Refuting Dating Methods Makes Untenable

The argon failed to degas from the minerals before the dacite solidified. Potassium-Argon 40K- 40Ar has been the most widespread method of radioactive age-dating for the Phanerozoic rocks, where most fossils occur. Austin simply assumes that the first explanation is correct and then he proceeds to use the 'presence' of 'excess argon' in his samples to question the reliability of all K-Ar dates on other rocks and minerals. If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them. One example would come from my book, the fourth chapter is available on the AiG page today and deals with that very topic.

Essentially all of these strongly favor an old Earth. Lastly, this is not the first time I've been called out for using ambiguous time-terms regarding the history of science. Yet, instead of seriously attempting to rebut them with up-to-date evidence, Barnes merely quoted the old guesses of authors who wrote before the facts were known. In other words, it rose in intensity from 0. Again, a K-Ar date on such an impure 'fraction' would be meaningless and a waste of time and money. If we are really just animals, living an existence for 60, 70, 80 years or more if we are lucky, what difference does any of this make? Answer: If anything, the tree-ring sequence suffers far more from missing rings than from double rings. Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.

And note that these dates are presented in this table on page 30 of the study—the specific page referenced by Eric Hovind as the source of this quote—so what is going on here? I knew I was forgetting something! I have witnessed God evidently at work in my life, my churches life, and my families life. It is just a matter of taxonomy. Christianity says that humanity has a body, soul, and spirit. Index fossils typically have a short stratigraphic or vertical range. Although the mineral concentrates are not pure, and all contain some glass, an argument can be made that both mafic and non-mafic minerals of the dacite contain significant 40Ar.

Young-Earth Creationist 'Dating' of a Mt. The most important point to make and understand is that there isn't just one dating method used in isolation; instead, there are a variety of dating techniques that are used—all of which serve as checks on one another and all of which yield the same results. Cohen, 1994, Introduction to Logic, 9th ed. In order to believe in the inerrency of Scripture and therefore be able to have full assurance in the Scripture being the Word of God, you must believe in everything in the scripture. Technical details on how these dates are calculated are given in. To confirm this, experiments were conducted on lava that erupted during historical time at Rangitoto, which had previously resulted in discordant K—Ar ages ranging from 146±12 to 465±11 ka McDougall et al. For me, this blog is a means to that end, as it challenges me to better understand each subdiscipline to respond to claims made within the Young-Earth Creationist movement.

Concluding remarks In this particular article, I think it is clear that Mr. It is not an answer to the meaning of life and does not pretend to be. This equals the length of time needed for 50% of a quantity of radioactive material to decay. Considering Contamination From : Carbon-14 is considered to be a highly reliable dating technique. No, nobody knows more about potential sources of error in radiometric dating than the people who regularly use these dating methods. Evolutionists assume that as soon as a crystalline rock cooled from melt, it inherited no daughter product from the melt.

The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using , at some age which is a lot below the 'usual' i. Likewise, people actively looking for incorrect radiometric dates can in fact get them. To estimate a radioisotope age of a crystalline rock, geologists measure the ratio between radioactive parent and stable daughter products in the rock. There are many different kinds of creationism, but all of them include a rejection of most parts of modern evolutionary biology. Other species of trees corroborate the work that Ferguson did with bristlecone pines. Only substances with much longer half-lives are used for dating the age of the earth, such as radioactive forms of Rb Rb-87 , which has a half-life of 48 billion years. The results from all of the laboratories were remarkably consistent with the measured ages ranging only from 64.

Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 N-14 into carbon-14 C-14 or radiocarbon. On top of that, the two samples were collected years apart! According to Christianity, when we are baptized in the Holy Spirit, we are given the power to overcome sin and our spirits are awakened. If the sample contained this ratio, then the rock would be declared 1. It is understandable that Miller et al. Introduction to the controversy Over the years, Answers in Genesis has committed to undermining the credibility of radiometric dating techniques.
