Isotope used in radiometric dating

Radioisotope dating shows the earth to be billions of years old. T38, 4: What We Really Know about Dating Methods When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating. However, there are many methods that can be used to determine the age of the earth or other objects. The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.

Relative ages are assigned to rocks based on the idea that rock layers lower in the strata were deposited before rock layers that are higher. There is also a difference in the timescale used to explain the layers.

Determining the relative age of a rock layer is based on the assumption that you know the ages of the rocks surrounding it. Uniformitarian geologists use so-called absolute dating methods to determine the ages of the surrounding rocks. Certain types of rocks, especially those that form from magma igneous , contain radioactive isotopes of different elements.

It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in a rock, but the ratios are not dates or ages. The dates must be inferred based on assumptions about the ratios. Radiometric Dating Using ratios of isotopes produced in radioactive decay to calculate an age of the specimen based on assumed rates of decay and other assumptions. Carbon dating is another common technique, but it can only be used on carbon-containing things that were once alive.

The method of calculating radiometric dates is like using an hourglass. You can use the hourglass to tell time if you know several things: If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time. Using an hourglass to tell time is much like using radiometric dating to tell the age of rocks. There are key assumptions that we must accept in order for the method to be reliable.

Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements. The starting isotope is called the parent and the end-product is called the daughter. The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life.

If certain things are known, it is possible to calculate the amount of time since the parent isotope began to decay. For example, if you began with 1 gram of carbon, after 5, years you would be left with 0. The reason this age may not be a true age—even though it is commonly called an absolute age—is that it is based on several crucial assumptions.

Most radiometric dating techniques must make three assumptions: The rate of radioactive decay is known and has been constant since the rock formed. There has been no loss or gain of the parent or daughter isotopes from the rock. The amounts of parent and daughter isotopes present when the rock formed are known.

The major problem with the first assumption is that there is no way to prove that the decay rate was not different at some point in the past. It is true that radioisotope decay rates are stable today and are not largely affected by external conditions like change in temperature and pressure, but that does not mean that the rate has always been constant.

Recent research by a creation science group known as RATE Radioisotopes and the Age of The Earth has produced evidence of accelerated rates of decay at some point or points in the past. Creation scientists suggest that there are two possible times that God supernaturally intervened on a global scale—during Creation Week and the Flood.

It is not unreasonable to assume that God used the energy of accelerated radioactive decay to initiate and drive the major geologic changes in the earth that accompanied the Flood. Evidence for the period of accelerated decay is found in zircon crystals. Zircon crystals in granite contain radioactive uranium, which decays into lead over time. As the uranium decays, helium is produced in the crystals.

Helium escapes from the crystals at a known, measurable rate. If those rocks were over a billion years old, as evolutionists claim, the helium should have leaked out of the rock. The presence of lots of helium in the crystals is evidence in support of a young earth. Fossils and rocks do not come with dates stamped on them. The dates must be interpreted based on the evidence.

Biblical geologists start with the assumptions laid out in the Bible and conclude that the rocks must be less than 6, years old. Evolutionists reject the authority of the Bible and conclude that the rocks must be millions or billions of years old. Other important findings of the RATE project include detecting carbon in coal and diamonds.

If these substances were really millions or billions of years old respectively, there should be no carbon left in them. Carbon has a half-life of 5, years. With the most accurate mass spectrometers, the oldest calculated age of items containing carbon is about 80, years. Diamonds are assumed to be many billions of years old and should contain no detectable carbon as it would have all decayed to nitrogen long ago.

The same is true of coal which was supposedly deposited hundreds of millions of years ago, according to the evolutionary model. The presence of carbon in these materials clearly supports the idea of a young earth as described by the Bible. The assumption that there has been no loss or gain of the isotopes in the rock assumption 2 does not take into account the impact of weathering by surface and ground waters and the diffusion of gases.

It is impossible to know to what degree the parent and daughter products have been added to or removed from the rocks over the alleged millions or billions of years. Also, samples taken a few feet apart can give ages that differ by many hundreds of millions of years. Many people do not realize that fossils themselves are usually not directly dated. Instead, layers that contain datable igneous rocks above or below a fossil-bearing layer are used to estimate the age of the fossil.

The age of the fossil can be estimated within the range of the layers above and below it. In some cases, the ages are correlated to other rock layers of supposedly known age or by using index fossils. These methods assume that the distribution of index fossils and the correlation of strata are well understood on a global scale. Another finding of the RATE team is very intriguing.

The team took samples of diabase, an igneous rock, and tested them using various radiometric dating techniques. If the dating methods are all objective and reliable, then they should give similar dates. The rocks were tested as whole-rock samples using K-Ar dating and also separated into individual minerals. The whole-rock and separated mineral samples allow a method known as isochron dating to be done.

This method is supposed to eliminate the assumption that the initial concentration of the daughter element is zero. The facts from the rock layers do not speak for themselves—they must be interpreted.

The assumptions used to interpret the data influence the conclusion. Starting with the Bible produces different conclusions than starting with evolutionary reasoning. Despite removing this assumption, the RATE team has shown that this method is not reliable. Dating the Cardenas Basalt, a layer near the bottom of Grand Canyon, and a volcanic layer from near the top of Grand Canyon produced an amazing result.

Based on the law of superposition, the lower layers in the canyon should be older than the upper layers unless there was an intrusion or other event that changed the order. Using isochron dating from a respected lab, the lower rocks were dated at 1. There is an obvious discordance disagreement in the data. Because these dates are based on methods with multiple assumptions, and are contrary to the Bible, we must reject that they are accurate. There are many other methods that can be used to establish ages for parts of the earth and the solar system.

These methods will be discussed in the following chapter. Regardless of what method we use, we must start with assumptions and interpret the facts accordingly. Understanding what those assumptions are is important. If we are not aware of the assumptions that are being used, we can easily be deceived. We should always start with the Bible, the ultimate source of truth.

Reference Article Summaries Riddle, www. But what is this age based on? A straightforward reading of the Bible shows that the earth was created in six days about 6, years ago. Radiometric dating uses ratios of isotopes in rocks to infer the age of the rock. Scientists use a mix of observational data and assumptions about the past to determine the radiometric age of a rock. Comparing the amount of a parent isotope to the amount of its daughter isotope and knowing the rate of change from parent into daughter known as the half-life , the age of the rock can be determined.

However, there are several assumptions that must be made in this process. The three critical assumptions are: The initial conditions of the rock sample are accurately known. The amount of parent or daughter elements in a sample has not been altered by processes other than radioactive decay.

The decay rate or half—life of the parent isotope has remained constant since the rock was formed. An hourglass can be used as an analogy to explain the assumptions. An hourglass can be used to tell time only if we know how much sand was in each chamber at the beginning, that there was no sand added or removed from either chamber, and that the sand falls at a constant rate. If any of these factors is not known, the time given may not be accurate.

The same goes for the dating of rocks using radioisotopes. Assumption 1 was proven false when scientists from the RATE group had rocks of known age dated. These rocks were dated at up to 3. How can we trust this method to tell us the age of rocks when the data do not match with observations?

Isochron dating is supposed to remove the assumption of initial conditions, but some different assumptions are necessary.

  1. These cool quickly and have small crystals and form basalt. There may be evidence of heating, but the date may be accepted, and there may be no such evidence, but a hypothetical heating event is assumed anyway.

  2. Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. In the atmosphere of the earth, Ar40 constitutes This is at least close to what I am looking for.

  3. Furthermore, some elements in the earth are too abundant to be explained by radioactive decay in 4. This is computed from the current quantity of parent isotope plus the accumulated quantity of daughter isotope. As for the other methods, some minerals when they form exclude daughter products.
