See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric  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. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days? Christians , by definition, take the statements of Jesus Christ seriously. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. We will deal with carbon dating first and then with the other dating methods.

Scientific dating has confirmed the long residence of Aboriginal people in Australia. A number of methods are used, all of which have their advantages, limitations and level of accuracy. Complex dating problems often use a variety of techniques and information to arrive at the best answer. Artefacts and other materials can be dated in relative terms by observing which layer of sediments they are found in.
This applies the geological principle that under normal circumstances younger layers of sediment will be deposited on top of older layers. This ‘law of superimposition’ works in the well-defined layers of the Willandra lunettes , but only dates objects as younger or older than adjacent layers.
If this is the case, then a number of implications follow.
Everything Worth Knowing About Scientific Dating Methods This dating scene is dead. The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. Sometimes only one method is possible, reducing the confidence researchers have in the results. Methods fall into one of two categories: These methods — some of which are still used today — provide only an approximate spot within a previously established sequence: Think of it as ordering rather than dating.
One of the first and most basic scientific dating methods is also one of the easiest to understand. Paleontologists still commonly use biostratigraphy to date fossils, often in combination with paleomagnetism and tephrochronology. A submethod within biostratigraphy is faunal association:

These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.
Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried. As a result, glauconite is used for dating only with extreme caution. The ages from the Coast Range batholith in Alaska Table 2 are referenced by Woodmorappe to a report by Lanphere and others
He has used an invalid analogy and come to an erroneous conclusion.
Dublin-based Karelian Diamond Resources has announced that an extensive work programme is underway to find the source of the green diamond discovered by the company earlier this year. In January the company confirmed that it had discovered a green diamond in Finland. The work programme follows on from the high kimberlite indicator minerals “KIMs” counts reported in September, which has considerably narrowed down the search area, a statement from Karelian said.
The objective of the programme is to locate the kimberlite body from which the green diamond originated. As a kimberlite body erodes over millions of years KIMs spread out to form a fan shaped train which may extend for many kilometres. The work programme is designed to identify the kimberlite train and follow it back to source.

Mode 3 technologies and the evolution of modern humans. Cambridge Archaeological Journal 7 1: While the archaeological record has been used to support or refute various aspects of the theories, and to provide a behavioural framework for different biological models, there has been little attempt to employ the evidence of stone tool technology to unravel phylogenetic relationships.
Here we examine the evidence that the evolution of modern humans is integrally related to the development of the Upper Palaeolithic and similar technologies, and conclude that there is only a weak relationship. The implications of this for the evolution of Neanderthals, the multiple pattern of human dispersals, and the nature of cognitive evolution, are considered.
Ground-water and erosional water movements could produce this effect naturally.
The isochron method Many radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughter-type isotopes already exists. These isotopes did not come from radioactive decay in the system but rather formed during the original creation of the elements. In this case, it is a big advantage to present the data in a form in which the abundance of both the parent and daughter isotopes are given with respect to the abundance of the initial background daughter.
The incremental additions of the daughter type can then be viewed in proportion to the abundance of parent atoms. In mathematical terms this is achieved as follows. This term, shown in Figure 1, is called the initial ratio. The slope is proportional to the geologic age of the system. In practice, the isochron approach has many inherent advantages. When a single body of liquid rock crystallizes, parent and daughter elements may separate so that, once solid, the isotopic data would define a series of points, such as those shown as open circles designated R1, R2, R3 in Figure 1.
With time each would then develop additional daughter abundances in proportion to the amount of parent present. If a number of samples are analyzed and the results are shown to define a straight line within error, then a precise age is defined because this is only possible if each is a closed system and each has the same initial ratio and age. The uncertainty in determining the slope is reduced because it is defined by many points.

He performed admirably in all three and Cheika even went so far as to say he was one of two standout Australian players across the three matches. An ankle injury late in the Super Rugby seasin halted Hunt’s momentum and he did not return for the Wallabies until the Wales match in Cardiff, off the bench.

This would make things which died at that time appear older in terms of carbon dating.
Preliminary papers in the late s suggested either Zhamanshin  or Elgygytgyn  as the source of the Australasian strewnfield. Povenmire and others have proposed the existence of an additional tektite strewn field, the Central American strewn field. Evidence for this reported tektite strewn field consists of tektites recovered from western Belize in the area of the villages of Bullet Tree Falls, Santa Familia and Billy White.
A limited amount of evidence is interpreted as indicating that the proposed Central American strewn field likely covers Belize, Honduras, Guatemala, Nicaragua and possibly parts of southern Mexico. It is speculated that the hypothesized Pantasma Impact Crater in northern Nicaragua might be the source of these tektites. Similar agreements exist between tektites from the North American strewnfield and the Chesapeake Bay impact crater and between tektites from the Ivory Coast strewnfield and the Lake Bosumtwi Crater.
How Old is the Earth
Carbon 14 is used for this example: This nullifies the carbon method as well as demonstrating that the earth is less than 10, years old. The above is offered as a simple fact of research. Knowing how faulty creationist “facts” can be, let’s do a little research of our own. One suspects that the scientific world would not be using the carbon method if it were so obviously flawed.
Lyell proposed that scientists build geological theories upon observable causes to reconstruct the past.

Then, two weeks after publishing his findings, he was fired. Now California State University at Northridge has paid Armitage a six-figure sum to settle his wrongful termination suit based on religious discrimination. The case of Armitage is the latest to show the mounting hostility Christians face in academics and other public arenas. The whole discussion of evolution ends if you show that the earth is young.

There are five stable isotopes 40Ca, 42Ca, 43Ca, 44Ca and 46Ca , plus one isotope 48Ca with such a long half-life that for all practical purposes it can be considered stable. The most abundant isotope, 40Ca, as well as the rare 46Ca, are theoretically unstable on energetic grounds, but their decay has not been observed. Calcium also has a cosmogenic isotope , radioactive 41Ca, which has a half-life of , years.
Unlike cosmogenic isotopes that are produced in the atmosphere , 41Ca is produced by neutron activation of 40Ca.

Everything Worth Knowing About … Scientific Dating Methods
Outlook Other Abstract U-Pb radioisotope dating is now the absolute dating method of first choice among geochronologists, especially using the mineral zircon. A variety of analytical instruments have also now been developed using different micro-sampling techniques coupled with mass spectrometers, thus enabling wide usage of U-Pb radioisotope dating.
However, problems remain in the interpretation of the measured Pb isotopic ratios to transform them into ages. Among them is the presence of non-radiogenic Pb of unknown composition, often referred to as common or initial Pb. There is also primordial Pb that the earth acquired when it formed, its isotopic composition determined as that of troilite in the Canyon Diablo iron meteorite.
More recently, it has been found that of all the grains present in a rock a very few still retain closed isotopic systems but only in their interior parts.
