In its simplest form, the geologist simply needs to measure the relative amounts of potassium-40 and argon-40 to date the rock. I thank my wife Gwen, and children, Carson and Isaac, for solo me in this work, and I thank God for giving us the intelligence to understand little bits and pieces of His amazing creation. This article radiometric dating christian perspective originally posted by Dr. Are we suggesting that evolutionists are conspiring to massage the data to get what they want. Furthermore, they may pan minerals that are rare in igneous or sedimentary rocks, such as garnet, cordierite, kyanite, and andalusite. Polar ice dating layers, counting back yearly layers, consist of the following: Summer ice has more bubbles christuan larger crystal sizes. Solid arrows represent direct decay, while dashed arrows indicate that there are one or more pan decays, with the longest intervening half-life given below the arrow.
There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn't know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10,000 years old. Radiometric methods measure the time elapsed since the particular radiometric clock was reset. Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead. It measures the time elapsed since death, but is limited in scale to no more than about 50,000 years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified. If that happens to be longer than 10,000 years, then the idea of a young-Earth is called into question. If that happens to be billions of years, then the young-Earth is in big trouble. As of January, 1999, The oldest rocks found on earth are 4. This is reported in the paper Priscoan 4. Williams; 134 1 : 3-16, January 1999. The previous record was 3. The putative age of the Earth, about 4,500,000,000 years is based on the radiometrically measured age of meteorites, and is also about 500,000,000 years older than the oldest rocks. But regardless of the accuracy of this age for the earth, the existence of rocks circa 4,000,000,000 years old puts the squeeze on a 10,000 year old Earth. So the natural response from a young-Earth perspective is to claim that radiometric dating is inaccurate or untrustworthy. Unfortunately, while the young-Earthers are long on criticism, they are short on support. It's easy to assert that radiometric methods don't work, but it's quite another thing to prove it. This the young-Earth creationist regularly fails to do. I am not going to try to write a web-treatise on radiometric dating myself, simply because much better qualified writers have already done a much better job than I could. This is a list of resources, some on the web, some not, which can be consulted by anyone interested in learning more about how radiometric dating is done, or in responding to arguments criticising radiometric dating. My purpose is to show, through these resources that young-Earth creationist criticisms of radiometric dating are inadequate at best. So long as radiometric dating stands as scientifically valid, then the assertion of a young-Earth is falsified by direct observation. The argument from radiometriic dating is the strongest scientific argument that can be brought to bear on this issue, in my opinion. There may be some sense of repetition, as there are a number of one-page, introductory type entries. But I put them all in anyway, figuring some readers would understand one more easily than the other. Kevin R Henke, Part 3 by Dr. David Plaisted was at the time a post doctoral fellow in the at the. He is now August 2005 a researcher for at the same school. It is an extensive collection of pro-creationist material that extends well beyond radiometric dating. So far as I know all of the material was written by Dr. Henke on the talk. Part 2 was provided by Henke; it is Plaisted's response to the critique with Henke's posted comments. Part 3 was provided by Plaisted, and are his remarks in further response to Henke. Look for this page to change, or for new responses to appear, as Dr. Plaisted continues his own research. There is also another copy of this page, though perhaps not as current as his own, as well. He is also a member of the is a pseudonymous pro young Earth creationist, and allegedly a scientist. He is the author of several books and papers; one of those papers, Radiometric Dating Reappraised is the target of Schimmrich's original critique. Woodmorappe responded to that critique, hence Schimmrich's additional response. Since Woodmorappe is a popular source for pro young-Earth creationists, this detailed discussion of his work by a qualified Christian geologist is a good reference source. Dave Matson is a mathematician and editor of his own. Radioisotopes and the Age of The Earth project, a program out of the ICR , one of the leading young-Earth creationist organizations see their , July 1998. Meert demonstrates the scientific weakness of the study. This is a well illustrated article that brings together stratigraphy, relative time scales, and the absolute chronometry provided by radiometric dating. It is a common assertion from young-Earthers that dating techniques are circular; that fossils are dated according to their strata and that the strata are dated according to their fossils. The assertion is flatly false. The majority of material is on radiometric dating, although some other faulty young-Earth age arguments are addressed as well. Data, results, and faulty methodologies are all addressed. Of particular interest is some tabulated data from Dalrymple's Age of the Earth see below. These data well illustrate the internal consistencies of radiometric dating methods. A well written article worth reading. But this is an urban legend, as Lindsay points out. Also see his page for much more material on creationism, including other radiometric topics. In the reliability section below, there is a discussion of how rates might be made to vary. But here Joe Meert explains the consequences we would expect today, if in fact decay rates were variable in the past. An Australian high school student asks the question, which was routed to Dr. A good, brief explanation of how reliable radiometric dating really is. Meert shows where different radiometric methods return concordant dates for a given sample or region. If radiometric dating really does not work, one would not expect different methods to return concordant ages. The page inculdes a chart of radiometric ages of the volcanoes in the Hawaiian chain. But the plot of age versus distance from is significant. It shows a clear linear slope, a strong, direct correlation between the tectonic motion of the Pacific Plate over the , and the age of the Hawaiian Island chain. Once more, a clear correlation between radiometric dates, and independent date indicators. In these two short items, Lindsay shows that absolute radiometric dates are consistent with relative geological dates, and that the various radiometric methods are consistent with each other. From 78 28 : 285,288-289 July 15, 1997 , a weekly newspaper of geophysics from the. This evidence of strong agreement between disparate dating methods is another example of the consistency between radiometric dating and nature, and another demonstration of reliability. Hilgen is a professor in the at , Netherlands. The Hilgen et al. Here, I reference a paper that is a good example of concordance between radiometric dating and luminescence dating, a technique that takes advantage of electrons trapped in crystal lattice defects. It is a common creationist ploy to argue that radioactive decay rates either are, or can be, variable; since radiometric dating always assumes a constant decay rate, it is therefore unreliable. But in this item from the , we see how and why decay rates can and do vary. We also see that the variable decay rate argument is a dead argument. Not only does the variability not apply at all to most radiometric isotopes, but even in those cases where it does apply, the affect is at the less than one percent level, under conditions that are unrealistically extreme for any practical application to radiometric dating. Today he is a member of the at the in New Mexico. His article is hosted by the ASA. But Wiens and the ASA exemplify the fact that, even amongst Christians, the young-Earth is a minority position. Woolf describes himself as an enthusiastic amateur. But if you are looking for radiometric dating for dummies, or some such explanation, aimed at the general reader, this may be the one that does it for you. Gore Hosted by and ; Dr. Gore is on the faculty of Georgia Perimeter College. This is a brief tutorial introduction to the basic principles of radiometric dating, designed for community college students of geology. These are course notes for Dr. Grossman's , , at. These pages are part of , a USGS. There is a little about how radiometric dating is done, but really not much. The main value here is that the results of radiometric dating are well presented. Find out how radiometric dating is done from one of the other sites, and find out what it all means here. Isochron dating is a robust application of the radiometric principles which has the advantage of being insensitive to the initial concentration of daughter product. This is really an intermediate level article, designed for general readers, but it is not something to read lightly. He is the owner of. Introduction to radioactive decay and nucleosynthesis. Includes applications to palaeoclimatology. The entire set of notes for 37 lectures will give you a 273 page book on isotope geochemistry, free. Hosted by the , in the at , Ithica, New York. Here you will find a complete description of the basic principles, the applied techniques, and how dates are corrected for the known variations in atmospheric carbon abundances the use of tree ring calibration is important. Includes to various radiocarbon laboratories, and downloadable software. This proposal is an interdisciplinary initiative of archaeologists and nuclear physicists to substantially improve the absolute chronology of archaeologically interesting cultures in Austria and Central Europe by using 14C dating with Accelerator Mass Spectrometry AMS. An improved absolute chronology based on precise 14C dating would lead to a better understanding of the interactions between early cultures and would help to deepen our insight into the rich diversity of pre-historic life in Austria and adjacent countries. The 14C dating will be performed at the VERA , a new centre for AMS at the of the , which came into operation in 1996. The project description is in English and in considerable detail. This is a good example for those who want to see a detailed account of how it is all really done. Complete physical, chemical, thermodynamic, and even historic information on elements and isotopes. Not as much nuclear specific information as the table of nuclides listed below, but lots of additional stuff. This is where you look up things like decay modes, half life, decay energy, and so forth. It's easier to work your way through an entire decay chain using these tables, but if you want lots of info on one element, the page is better. Books You remember - what we used to read before computers I have included here only such books as I know of, or are recommended. Some I am aware of I have left off because they are out of print and I don't know much about them. Books included are both advanced and general, but all bear either directly or indirectly on the radiometric dating problem. For each book, the title is linked to an entry if there is one so far we are batting 100%. Authors are linked to their own homepages, or the functional equivalent, wherever I could find one. A long time veteran of the , he was Dean of the at , but is now retired, and an Emeritus Professor. Dalrymple is a well recognized authority in the field of radiometric dating. His book, published by the in 1991, is the only book I know of which deals directly and in detail with the age of the Earth. It is written for non-technical readers, but it is not lacking in content. This book is a must-read for anyone interested in knowing how we know the age of the Earth. It presents perhaps the strongest case against the idea of a 10,000 year old Earth. This book is not for general audiences, it is a technical book aimed at students of physics and geophysics. The book goes beyond an explication of the basic principles, and delves into the applications of radiometric dating. The link goes to the 1997 reprint; the original appeared in 1995. Dickin also makes available a. Like Faure's book, this is a physicists text, not intended for general audiences. Detailed explications of dating methods, as well as isotope geochemistry. Includes fission track dating, which was not covered in my 1977 edition of Faure. C Bowen Don't believe the Amazon typo, it was published in 1988, not 1899. In fact, with this title, it should be the 1997 2nd edition. Besides radiometric dating methods and isotope geochemistry, this book also deals with isotopic analysis and climate. Both authors are formerly from the , affiliated with , Münster, Germany. Mark Harrison Oxford Monographs on Geology and Geophysics 9, 1988;. Publication of a new second edition, again by the , is scheduled for June 1999. Berggren, editor December, 1995; Special Publication 54 of the. Currently out of print, but may be available through the society. The work doesn't treat the matter of isotopic geochemistry in general, but rather concentrates on a more complete and practical guide to dating methods. The first chapter collates general data and principles common to all methods. The following chapters present the possibilities and limitations of the different dating methods, along with the relevant analytical techniques and the preferred range of application. Includes two glossaries, isotope tables, a scale of geological times, and a chapter on radioactivity. Annotation copyright Book News, Inc.
