The Thorium Lead Dating Method

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. We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points. Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.

The above and below videos are amazing videos by Creationists and I strongly advise that you take a look at them. Hovind explains what is the age of the Earth. Some of you, especially the evolutionists, may immediately object to say: What in the world are you and Dr. Science have proven this age a long time ago!

The Thorium Lead Dating Method. By Paul Nethercott. September How reliable is radiometric dating? We are repeatedly told that it proves the Earth to be billions of years old.

Jews in these regions used Seleucid Era dating also known as the “Anno Graecorum AG ” or the “Era of Contracts” as the primary method for calculating the calendar year. Jacob then put this question: How do we know that our Era [of Documents] is connected with the Kingdom of Greece at all? Why not say that it is reckoned from the Exodus from Egypt, omitting the first thousand years and giving the years of the next thousand?

In that case, the document is really post-dated! In the Diaspora the Greek Era alone is used. He [the questioner] thought that Rav Nahman wanted to dispose of him anyhow, but when he went and studied it thoroughly he found that it is indeed taught [in a Baraita ]: In the 8th and 9th centuries AD, the center of Jewish life moved from Babylonia to Europe, so calculations from the Seleucid era “became meaningless”. In the section Sanctification of the Moon The first year of the Jewish calendar, Anno Mundi 1 AM 1 , began about one year before Creation, so that year is also called the Year of emptiness.

A year earlier, the first day of AM 1, Rosh Hashanah 1 Tishrei , is associated with molad tohu new moon of chaos , so named because it occurred before Creation when everything was still chaotic — it is also translated as the new moon of nothing. The Septuagint was the most scholarly non-Hebrew version of the Old Testament available to early Christians. Many converts already spoke Greek, and it was readily adopted as the preferred vernacular-language rendering for the eastern Roman Empire.

The later Latin translation called the Vulgate , an interpretative translation from the later Masoretic Text a Jewish revision and consolidation of earlier Hebrew texts , replaced it in the west after its completion by St.

Creation Evidence and Evolution Myth

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way.

At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column.

Radiometric dating breakthroughs. by With the release of key peer-reviewed papers at the ICC (International Conference on Creationism), it is clear that RATE has made some fantastic progress, with real breakthroughs in this area. A young age for ‘ancient’ granites.

Hank Campbell In the latest episode of Cosmos we got some history regarding how science has tried to converge on the age of the Earth. With that, we also got another jab at religion. Why use yet another religious contrast from hundreds of years ago to show the awesome power of science now? Is there so little actual imagination in their Ship Of The Imagination?

It’s a short bit and so less grievous to our intellectual senses than the 25 percent of episode 1 they devoted to creating an alternate history of Giordano Bruno , but in this case what is interesting is not what they add in, but what they leave out. In , Archbishop James Ussher of Ireland calculated a date for the creation of the universe using the Bible as a reference.

I don’t know, people just did that kind of thing and still do. The Bible is as accurate a history as most ancient histories and mapping science data to history still happens today. If you watched the History Channel this Easter weekend, you know it was chock full of science-y explanations for everything in the Bible.

More Bad News for Radiometric Dating

This belief in long ages for the earth and the existence of life is derived largely from radiometric dating. These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio. This age is computed under the assumption that the parent substance say, uranium gradually decays to the daughter substance say, lead , so the higher the ratio of lead to uranium, the older the rock must be.

Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning. 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 often used to “prove” rocks are millions of years old. Once you understand the basic science, however, you can see how wrong assumptions lead to incorrect dates. This three-part series will help you properly understand radiometric dating, the assumptions that lead to.

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, 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, 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, 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, , The oldest rocks found on earth are 4.

Unreliability of Radiometric Dating and Old Age of the Earth

The assumption that the geologic column is a base from which to calibrate the C dates is not wise. With a half-life of only years, carbon dating has nothing to do with dating the geological ages! Whether by sloppiness or gross ignorance, Dr.

How radiometric dating works in general: Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is .

This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating – A Christian Perspective.

This is the crucial point: Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint. A full discussion of the topic must therefore include the current scientific challenge to the OE concept. This challenge is mainly headed by Creationism which teaches a young-earth YE theory.

Clocks in the Rocks

Calendar era It is not known who invented the World era and when. Nevertheless, the first appearance of the term is in the treatise of a certain “monk and priest”, Georgios AD —39 , who mentions all the main variants of the “World Era” in his work. He also already regards it as the most convenient for the Easter computus.

One of the very foundations of evolution and popular science today is the “geologic column.” This column is made up of layers of sedimentary rock that supposedly formed over millions and even billions of .

While there are numerous natural processes that can serve as clocks, there are also many natural processes that can reset or scramble these time-dependent processes and introduce uncertainties. To try to set a reasonable bound on the age, we could presume that the Earth formed at the same time as the rest of the solar system. If the small masses that become meteorites are part of that system, then a measurement of the solidification time of those meteorites gives an estimate of the age of the Earth.

The following illustration points to a scenario for developing such an age estimate. Some of the progress in finding very old samples of rock on the Earth are summarized in the following comments. It is a compound of zirconium, silicon and oxygen which in its colorless form is used to make brilliant gems. Samples more than 3. Older ages in the neighborhood of 4. The graph below follows the treatment of Krane of Rb-Sr studies of meteorite samples from Wetherill in order to show the nature of the calculation of age from isochrons.

Considering the relative scale of nuclei and atoms , nuclei are so remote from the outer edge of the atoms that no environmental factors affect them.

The Age of the Earth

This thing all things devours: Birds, beasts, trees, flowers; Grinds hard stones to meal; Slays kings, ruins town, And beats high mountain down. This riddle exemplifies how time normally results in decay and destruction. So, why are people so interested in the topic of time?

Uranium-Lead dating is a radiometric dating method that uses the decay chain of uranium and lead to find the age of a rock. As uranium decays radioactively, it becomes different chemical elements until it stops at lead. The reason for stopping at lead is because lead is not radioactive and will not change into a different element.

The first two-thirds of this essay deals with the rock formations of the Grand Canyon — what they are, and how and when they formed. This should be educational and understandable to readers without a science background. This essay is long. The low rainfall in the region reduces vegetative cover, so the colorful rock layers remain exposed to view. This deep gash in the earth provides a window into the geological past. Nearly all geologists understand these layers to have been deposited over the course of hundreds of millions of years.

This essay starts with a tour of the Grand Canyon, noting evidence that shows the Canyon rocks are indeed very old. YE creationists hold to a literal interpretation of the Bible, which does not adequately take into account the intent of the Scriptures or the historical circumstances of their authorship. YE creationists are convinced on religious grounds that the earth is only about years old, and that most of the sedimentary rock layers on earth including those in the Grand Canyon were laid down in the Noahic Flood around B.
