A letter in the 6th April edition of New Scientist drew my attention to the suggestion that Tony Blair believes creationism should be taught alongside evolution in the science curriculum. If this were to be implemented, it would strike fundamental blows to British science. Creationism often conjures visions of religious zealots who believe the book of Genesis verbatim. That is the Universe, Earth, Humanity and the plant and animal kingdoms were created in six days and that Noah’s flood led to the proven extinctions. This idea of creationism, it has to be said, is something of a biased view. As always there is a continuum of beliefs, most of which view creation to a greater or lesser extent as a complementary part of the evolutionary process. In fact, most of the Christian church believes in an extremely watered-down version of creationism that has been labelled Theistic Evolution. In this view, God is only involved in those processes which science cannot explain.

The Iconic Isochron: Radioactive Dating, Part 2

The Bible is quite clear about the origin and timeframe for the creation of Earth and the cosmos. If Scripture is inaccurate in this, then how can it be trusted in anything else? Some evolutionists throw out theistic evolution God using evolution as His creative process as a philosophical panacea, with the goal of leading people to conclude that Genesis is a myth.

Like Nimrod of ancient times, they know they must provide an alternative i. One of the indirect evidences that evolutionists universally appeal to is radioactive dating because it appears to supply the deep time their evolutionary models demand. But how accurate is their model, and how scientific is their approach?

Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava. Lava properly called magma before it erupts fills large underground chambers called magma chambers.

Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios. Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger. This calls the whole radiometric dating scheme into serious question.

Geologists assert that older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older. But even if it is true that older radiometric dates are found lower down in the geologic column, which is open to question, this can potentially be explained by processes occurring in magma chambers which cause the lava erupting earlier to appear older than the lava erupting later.

Lava erupting earlier would come from the top of the magma chamber, and lava erupting later would come from lower down. A number of processes could cause the parent substance to be depleted at the top of the magma chamber, or the daughter product to be enriched, both of which would cause the lava erupting earlier to appear very old according to radiometric dating, and lava erupting later to appear younger. The general idea is that many different minerals are formed, which differ from one another in composition, even though they come from the same magma.

The mineral makeup of an igneous rock is ultimately determined by the chemical composition of the magma from which it crystallized.

See this page in: Hungarian , Russian , Spanish. P eople who ask about carbon 14 C dating usually want to know about the radiometric [1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history.

A few years ago, some leading creationist geologists and physicists began a detailed research project into Radioactivity and the Age of The Earth (RATE). This.

Absolutely no one proposed or researched isochron dating as a response to creationists. Real geologists simply do not give a damn what creationists think. Isochron dating was developed to handle edge cases where other dating methods were not as precise as we would like. Literally no part of radiometric dating methods were in any way developed as a result of creationist objections. I, too, once thought that radiometric dating was an invention to prop up uniformitarianism and evolutionary biology.

It is not. No one cares.

The Radiometric Dating Game

Isochron dating is a common radiometric dating technique applied to date natural events like the crystallization of minerals as they cool, changes in rocks by metamorphism, or what are essentially naturally occurring shock events like meteor strikes. Minerals present in these events contain various radioactive elements which decay and the resulting daughter elements can then be used to deduce the age of the mineral through an isochron. The appeal of isochron dating is that it does not presuppose the initial amount of the daughter nuclide in the decay sequence.

Indeed, the initial amount is not important because it can be found through this type of dating. Isochron dating began when scientists recognized difficulties with the assumptions of radiometric dating, especially how much of the daughter products might have been present when the mineral first formed. Isochron dating has been developed in an attempt to solve such problems.

Many a stable 87 sr was the accumulation of radioisotope isochron method. Setting the creationist radioactive dating is the ways that 87 radiometric dating can.

The most commonly-used methods of dating geological formations involve the process of radioactive decay. Certain atoms are unstable, and their nuclei sometimes break apart and change into another element through a process known as “radioactive decay”. Some of these radioactive elements transform themselves by emitting a high-energy particle consisting of two protons and two neutrons, a process known as “alpha decay”.

Other radioactive elements decay when a neutron inside the nucleus breaks into a proton and an electron. The proton stays in the nucleus, and the electron is ejected at very high speed–a process known as “beta decay”. Probably the best-known of the radioactive elements is uranium, which is the heaviest element found in nature. The uranium nucleus comes in several versions.

An Essay on Radiometric Dating. Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth. All these methods point to Earth being very, very old — several billions of years old.

Here is one example of an isochron, based on measurements of for countering claims of creationists on the reliability of geologic dating.

How reliable are the radiometric methods used for geologic ages?

Jul 7. Posted by Paul Braterman. Can we trust radiocarbon dating? After all, it makes the same range of assumptions as other radiometric dating methods, and then some.

This has put creationists at a disadvantage in discussions of dating issues, and a mineral isochron gives excellent evidence that the date obtained is good.

A large fraction of the public still does not accept the most basic facts of modern geology, such as the notion that the earth is many millions of years old. For example, fully 45 percent of Americans insist that the earth was created at some time within the past 10, years [Gallup]. Much of this skepticism stems from the creationist movement, which has gone to great lengths to criticize the radiometric methods used to date rocks and fossils, such as Carbon, Rb-Sr and the K-Ar methods.

Indeed, geological dating methods, like the vast majority of scientific measurement techniques in many disciplines, are subject to anomalies. But such anomalies are hardly a secret in the field — they have been studied extensively in the literature, and most are well understood as due to various known phenomena — e. Modern dating procedures include steps to avoid such problems, and to cross-check results.

Along this line, because of its relatively short half-life, Carbon measurements can only be used to date relatively recent items — i. With regards to the Hualalai lava mentioned above, this is unusual because it includes numerous xenoliths, typically consisting of olivine, an iron-magnesium silicate material, that are foreign to the lava, having been carried from deep within the mantle as the authors of the study were careful to explain. If however they do all lie very nearly on a straight line which nowadays happens most of the time , then this is compelling evidence that the data are reliable [Baileya; Baileyb; Dalrymple; Stassen; Stassen].

New, high-tech equipment has eliminated many of the difficulties that afflicted earlier measurements.

Lorence G. Collins January The creationists are asking for equal time in science classrooms to teach that the Genesis stories are valid scientific interpretations of earth history. Equal time for creationists’ interpretations are not likely to occur in secular universities and schools, but if the creationist are serious about equal time, then they should be open to granting equal time in their private Christian schools for presentations of both sides of a scientific issue a literalist biblical view and the modern science view.

The origin, age, and other characteristic features of granite are such issues deserving equal time. The Bible says that the dry land was created on the Third Day of the Genesis Week Genesis , and presumably, this is the time in which granite in continental masses was formed. If I were given equal time in a science classroom at a private, fundamentalist, Christian college or secondary school, advocating creationists’ views, the following would be the kinds of information that I would provide for a modern scientific interpretation of granite to compare with the corresponding creationists’ biblical interpretation.

Geologists recognize that granite has several possible origins, depending upon the processes that operate on the rock systems. Some granites form 1 by magmatic processes, depending upon crystal settling and the order of crystallization of minerals from a magma melted silicate rock , 2 by melting of sedimentary rocks whose chemical composition is the same as that in granite, 3 by partial melting of rocks in which the first minerals to melt have the composition of granite, and, finally, 4 by chemical replacement processes Clark, ; Collins, ; Hunt et al.

Discussion of these different origins is not further expanded here because of space limitations and because it is sufficient to say that modern scientific studies show that granite is formed in many different ways, and these ways contrast with the creationists’ model in which granite has a single origin, being created nearly instantly by “fiat” e.

Radioactive decay has become one of the most useful methods for determining the age of formation of rocks. However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid. These assumptions include: 1 the initial amount of the daughter isotope is known, 2 neither parent or daughter product has migrated into, or out of, the closed rock system, and 3 decay has occurred at a constant rate over time.

But what if one or some combination of these assumptions is incorrect? Then the computed age based on the accumulation of daughter products will be incorrect Stasson In order to use the valuable information provided by radiometric dating, a new method had to be created that would determine an accurate date and validate the assumptions of radiometric dating. For this purpose, isochron dating was developed, a process “that solves both of these problems accurate date, assumptions at once” Stasson A natural clock must meet four requirements.

Isotope dating satisfies this requirement, as daughter products do not decay back to the original parent element.
