Bruce Malone gave his life to Christ over 20 years ago, as the Lord miraculously preserved him through a close call with death. Since that time Bruce has looked for a deeper purpose in life and realized that rejection of Biblical truth, justified by belief in evolution, is the acid which is eating away at the moral foundation of our culture. Bruce spent 27 years working as a research leader for the Dow Chemical Corporation, has a degree chemical engineering, and is responsible for key innovations which have resulted in 18 patents. But his passion is sharing the relevance and evidence for creation, so he retired early to become full time Director of Search for the Truth Ministries http: Bruce has spoken extensively at Colleges and Charities in 12 countries. Since Bruce has spoken over times to more than 20, people and over 30, books have been distributed to students and prisoners.
Unreliability of Radiometric Dating and Old Age of the Earth
Herbchronology Dating methods in archaeology[ edit ] Same as geologists or paleontologists , archaeologists are also brought to determine the age of ancient materials, but in their case the areas of their studies are restricted to the history of both ancient and recent humans. Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.
It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others. Nevertheless, the range of time within archaeological dating can be enormous compared to the average lifespan of a singular human being. As an example Pinnacle Point ‘s caves, in the southern coast of South Africa , provided evidence that marine resources shellfish have been regularly exploited by humans as of , years ago.
Dating methods in geology chronological dating, or simply dating, is dating methods in earth science the process of attributing to an object or event a date in the past, dating methods in geology allowing such object south asian dating sites or event to be ://
Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. The final decay product, lead Pb , is stable and can no longer undergo spontaneous radioactive decay. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus.
Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus. A particular isotope of a particular element is called a nuclide. Some nuclides are inherently unstable. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide. This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture.
Another possibility is spontaneous fission into two or more nuclides. While the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life , usually given in units of years when discussing dating techniques. After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a “daughter” nuclide or decay product.
In many cases, the daughter nuclide itself is radioactive, resulting in a decay chain , eventually ending with the formation of a stable nonradioactive daughter nuclide; each step in such a chain is characterized by a distinct half-life.
The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods.
· However the development of more precise dating methods, such as radiocarbon-dating and dendrochronology, has meant that that aspect of pollen analysis has faded away. Stratigraphic Palynology: Palynology is the branch of science dealing with microscopic, decay-resistant remains of certain plants and
Dating techniques Photo by: Bastos Dating techniques are procedures used by scientists to determine the age of an object or a series of events. The two main types of dating methods are relative and absolute. Relative dating methods are used to determine only if one sample is older or younger than another. Absolute dating methods are used to determine an actual date in years for the age of an object. Relative dating Before the advent of absolute dating methods in the twentieth century, nearly all dating was relative.
The main relative dating method is stratigraphy pronounced stra-TI-gra-fee , which is the study of layers of rocks or the objects embedded within those layers. This method is based on the assumption which nearly always holds true that deeper layers of rock were deposited earlier in Earth’s history, and thus are older than more shallow layers.
Radiometric dating In , shortly after the discovery of radioactivity , the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead. Analyzing specimens whose relative geologic ages were known, Boltwood found that the ratio of lead to uranium did indeed increase with age.
After estimating the rate of this radioactive change, he calculated that the absolute ages of his specimens ranged from million to 2. Though his figures were too high by about 20 percent, their order of magnitude was enough to dispose of the short scale of geologic time proposed by Lord Kelvin.
First Published 30 Jan Can we rely on radiometric dating techniques? How accurate are they? First, I’ll start by referring you to an extensive article on the young earth creation science website Answers in Genesis , titled “What About Carbon Dating? No, they are not. Yes, I agreed with the young earther on this one. But that doesn’t mean the earth is young. I can look in my scientific journals and see apparent discrepancies in dating techniques.
Some may be discrepancies…some may just need a bit further explanation. If there are possible discrepancies, how can I accept these dates as reliable? The young earth creationism believer thinks that all we are relying on is the radiometric techniques.
We have been told that dating methods, such as the rates of decay of radioactive elements, force an honest observer to an old-Earth conclusion. One of the most glaring problems with such reasoning is that it is based on assumptions that have proven to be incorrect. For years, that assumption has been shown to have serious problems DeYoung , and recent findings have made that assumption even more glaringly false. The implications of such a discovery are profound.
Stanford professor emeritus of applied physics Peter Sturrock stated:
· Age dating the Earth (Geochronology) is the scientific study of the age of the Earth and the temporal sequence of events related to the formation of the planet and the history of life on Earth. The word is derived from Geo meaning Earth, and chronology, which is the study of time, or a record of events in the order of their occurrence (timeline)
Being awarded a fellowship to attend the seminar, which was jointly funded by the Andrew W. Mellon Foundation and the National Endowment for the Humanities, enabled me to take the time to read deeply in the literature of the profession, where I discovered that the failings I had been seeing in American archival institutions were not primarily a consequence of bad management, but of the fact that the best methods of the profession were inadequate to the task at hand.
Since , I have not pursued this research directly and the work has remained dormant. I have spoken about it publicly from time to time, but have not forced others or myself to deal with its conclusions. Increasingly I have felt that this is irresponsible of me, and am glad to be bringing it out for public scrutiny at this time. In the process, the first four chapters have been substantially rewritten, but the underlying structure of the argument, and its conclusions, have not been affected.
Although references throughout the text were updated to reflect recent literature, the modest amendments and refinements of archival methods and practices proposed during the past three years have not required me fundamentally to revise my premises. The first four essays address the four fundamental activities involved in the management of the physical record: Of each of these activities I ask whether our present methods are adequate and if not, how they can be adjusted within the practical limitations which cultural repositories face.

· This volume provides an overview of (1) the physical and chemical foundations of dating methods and (2) the applications of dating methods in the geological sciences, biology, and archaeology, in almost articles from over international authors. It will serve as the most comprehensive › Earth Sciences & Geography › Geochemistry.
Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters.
How does carbon dating work? Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen N into carbon C or radiocarbon. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C , and the old C starts to decay back into N by emitting beta particles. The older an organism’s remains are, the less beta radiation it emits because its C is steadily dwindling at a predictable rate.
So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. C decays with a half-life of 5, years. Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years. ICR creationists claim that this discredits C dating. How do you reply?
How Science Figured Out the Age of Earth
Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War. The Talmudic rabbis, Martin Luther and others used the biblical account to extrapolate back from known history and came up with rather similar estimates for when the earth came into being.
Within decades observation began overtaking such thinking. In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata.
· The generally accepted age for the Earth and the rest of the solar system is about billion years (plus or minus about 1%). This value is derived from several
