Question: What types of dating is there?

Are there different types of dating?

There are many different types of relationships, but the most common types are family relationships, friendships, romantic relationships, and business relationships.

What is dating and types of dating?

“Dating” means different things to different people, particularly across generations. At loveisrespect.org, we define “dating” as two people in an intimate relationship. The relationship may be sexual, but it does not have to be. It may be serious or casual, straight or gay, monogamous or open, short-term or long-term.

For since the fathers fell asleep, all things continue as they were from the beginning of creation. The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.

Far from being data, these dates are actually interpretations of the data. As discussed before, the assumptions influence the interpretation of the data. There are three main assumptions that must be made to accept radiometric dating methods. These must be accepted on faith in uniformitarian and naturalistic frameworks. Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.

Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem. A fear of and reverence for His Word is the beginning of wisdom. Starting with the Bible and developing a model for dating events in earth history will lead us to the truth. The Bible gives us a much more reliable history of the earth as it was recorded by God.

However, there are many methods that can be used to determine the age of the earth or other objects. What types of dating is there? 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 igneouscontain radioactive isotopes of different elements. It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in What types of dating is there?

rock, but the ratios are not dates or ages. The dates must be inferred based on assumptions about the ratios. Some of the common isotope pairs used are K-Ar, Rb-Sr, Pb-Pb, and U-Pb.

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-14 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 What types of dating is there?

What types of dating is there?

you know several things: the amount of sand in the top of the hourglass when it started flowing, the rate that the sand flows through the hole in the middle, and that the quantity of sand in each chamber has not been tampered with. 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 What types of dating is there? the parent isotope began to decay. For example, if you began with 1 gram of What types of dating is there?, after 5,730 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.

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. It is not unreasonable to assume that God used the energy What types of dating is there? 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.

What types of dating is there?

Zircon crystals in granite contain radioactive uranium-238, 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 6,000 years old.

Evolutionists reject the authority of the Bible and conclude that the rocks must be millions or billions of years old. If these substances were really millions or billions of years old respectively, there should be no carbon-14 left in them. Carbon-14 has a half-life of 5,730 years. With the most accurate mass spectrometers, the oldest calculated age of items containing carbon-14 is about 80,000 years.

Diamonds are assumed to be many billions of years old and should contain no detectable carbon-14 as it would have all decayed to nitrogen-14 long ago. The same is true of coal which was supposedly deposited hundreds of What types of dating is there? of years ago, according to the evolutionary model. The presence of carbon-14 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 What types of dating is there?

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. 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. What types of dating is there? assumptions used to interpret the data influence the conclusion. Starting with the Bible produces different conclusions than starting with evolutionary reasoning. 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 What types of dating is there? 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 What types of dating is there? 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 4:1 Does radiometric dating prove the earth is old? Riddle, Proponents of suggest that radiometric dating has proven that the earth is between 4. But what is this age based on? A straightforward reading of the Bible shows that the earth was created in six days about 6,000 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-lifethe age of the rock can be determined. However, there are several assumptions that must be made in What types of dating is there?

process. 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.

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. If radiometric dating techniques are objective and accurate, then comparing the single—sample What types of dating is there? to the isochron What types of dating is there? should give similar results. One volcanic rock layer from the top of Grand Canyon was dated 270 million years older than the oldest rocks below it near the bottom of the canyon.

The most reasonable explanation seems to be that the rates of decay have been different at some point in the past. This is supported by the presence of large amounts What types of dating is there? helium in some minerals. If there had been more than a billion years since the rocks had formed, the helium should have leaked out of the rocks by now.

What types of dating is there?

The presence of helium seems to support the recent accelerated decay of the isotopes, leaving a large amount of helium trapped in the rocks. The Bible presents a very different picture of the age of the earth when compared to radiometric dating using evolutionary assumptions.

Riddle, Radiometric dating is a technique that uses the change of one isotope, the parent, to another, the daughter, to determine the amount of time since the decay began.

Carbon-14 is supposed to allow dating of objects up to 60,000 years. If these dates were true, they would seem to discredit the biblical account of a young earth of about 6,000 years. Carbon-14 dating is used to date things that were once living. The unstable carbon-14 decays to stable nitrogen-14 as one of its neutrons is converted to a proton through beta decay. Carbon-14 is constantly supplied as high energy neutrons collide with nitrogen-14 in What types of dating is there?

upper atmosphere. This carbon-14 combines with oxygen to form carbon dioxide and is taken in by plants and then animals. Each living thing should have roughly the same ratio of radioactive carbon-14 to normal carbon-12. When an organism dies, it no longer takes in carbon-14, and the decay process begins. Assuming that the rate of decay and the starting amount of carbon-14 is known, this decay process can be used as a clock.

The plants and animals buried in the recent Flood could account for What types of dating is there? large change in the ratios What types of dating is there? demonstrate the false assumption of carbon equilibrium.

If these items were truly more than 100,000 years old, there should be no detectable carbon-14 present in them. These findings point to the age of the earth being much younger than evolutionary scientists would suggest.

Some of the findings are summarized below. The presence of fission tracks and radiohalos in crystals demonstrates that hundreds of millions of years worth of radioactive decay has occurred in a very short period. Because the Bible indicates the earth is young about 6,000 years oldthis large quantity of nuclear decay must have occurred at much faster rates than those measured today.

Using various radiometric dating methods to measure the ages of rock samples consistently produced ages that varied greatly. This may be explained by the different parent atoms having decayed at different rates in the past—an explanation not allowed by evolutionists. These changes in decay rates could be accounted for by very small changes in the binding forces within the nuclei of the parent atoms.

Research What types of dating is there? been done to demonstrate that many of the assumptions used in radiometric dating are false.

Starting from biblical assumptions regarding the Flood and Creation can provide a new framework for interpreting current scientific data. Native to the mountains of California and Nevada, the oldest tree has been dated at 4,600 years old.

By correlating the rings with dead wood found near the trees and beams from local buildings, a chronology of 11,300 rings has been suggested.

However, this does not necessarily correlate to years because multiple rings can grow in one year. The 4,600 year age of the oldest tree, named Methuselah, corresponds to the date of the Flood given by Ussher and others. If Methuselah began growing shortly after the Flood, then it stands as a record that confirms the Bible.

The layers of sediment are up to 400 meters thick and were supposedly laid down one layer at a time each year. Evolutionists assume the layers, called varves, roughly correspond to years based on assumptions about present processes. Varves are also used to date other lakes around the world to the time of the last ice age—supposedly 10,000 years ago.

Many other alleged varve deposits challenge the biblical timescale and must be reinterpreted within the creationist framework. The repeating layers should be referred to as rhythmites and simply represent successive deposits over time. These different layers can be deposited as particles of different size and density settle out of flowing water.

Studies at Lake Walensee, Switzerland, showed over 300 layers forming in 160 years. Different areas had different patterns and were not able to be correlated directly. Other studies have shown multiple layers forming as the result of light rainfall, increasing river flow, and increased snowmelt. Underwater turbidity currents are often interpreted as varves, but they form many layers rapidly. It is common, therefore, for multiple layers to form in a single year.

All of these layers can be explained within the Flood model as catastrophic melting and drainage events deposited many layers over a short period of time during localized residual catastrophism in the immediate aftermath of the Flood. Uniformitarian geologists assume the slow rate of deposition as observed today for the past. However, in many cases they really have not observed the present sedimentation rate, and in some cases where they have used sediment traps, not all the deposition has been recorded.
