How reliable is geologic dating?

Despite these, there are many other cases that illustrate just how inaccurate and unreliable radiocarbon dating can be. It seems they have not been accepted because they were not meaningful. He also never refuted my point that there is excess Ar in rock samples in which the source is not the atmosphere. The fact that dating techniques most often agree with each other is why scientists tend to trust them in the first place. He may suggest that some other very old material had contaminated the lava as it passed through the earth.

. Scientists have to assume that C-14 production has been a constant in order to calibrate their dating methods. Uranium Decay Equation Each individual atom has a chance of decaying by this process. Short-Period Comets Short-period comets orbit the sun in less than 200 years the Halley comet orbits about every 76 years. The age estimate could be wrong by a factor of hundreds of thousands. Even the method used for dating a sample can lead to dramatic changes in dates for an item.

Radiometric Dating — Is It Accurate?

These assumptions do not take into account the impact of weathering by surface and ground waters and the diffusion of gases. In broad terms this means the observed geological features are the result of slow geological forces of the same kind and intensity as those found today. It relates only to the accuracy of the measuring equipment in the laboratory. Does that make these studies fatally incomplete? The time required for half the original number of parent atoms to decay is called the half life. It is for this reason that creationists question radiometric dating methods and do not accept their results.

For this a batch of the pure parent material is carefully weighed and then put in front of a Geiger counter or gamma-ray detector. C14 is continually being created and decaying, leading to an equilibrium state in the atmosphere. Such drastic measures will help insure continued disbelieve in Gods existence. First, a bit of background information is in order. When we understand the science, we find that radiometric dating actually confirms the biblical account of history. A different god not having that property may still exist, but not the one originally claimed.

Similarly, If we discover a rock with 50% K-40 and 50% Ar-40, we know it has been solid for 1. Thus scientists are on very solid ground in asserting that rates of radioactivity have been constant over geologic time. Conclusions Radiometric dating has been demonstrated to give wrong age estimates on rocks whose age is known. Age is the concept of the amount of time an object has existed. The reliability of the dating is further enhanced by cross-checking in the same sample. And gas can indeed move through rocks, albeit rather slowly. We know they do because of the aforementioned tests on rocks whose origins were observed.

In any event, there is a simple way to see that the Earth must be at least 1. That proof is that the dates arrived by radiometry are verified by dendrochronology tree rings , varve chronology sediment layers , ice cores, coral banding, speleotherms cave formations , fission track dating, and electron spin resonance dating. Think of it like popcorn in the microwave. Since the method has been shown to fail on rocks whose age is known, would it make sense to trust the method on rocks of unknown age? Most physicists had assumed that radioactive half-lives have always been what they are today. However, there are numerous examples, but I only have limited space on this forum. The assumptions of initial conditions, rates, and closed-ness of the system are involved in all scientific attempts to estimate age of just about anything whose origin was not observed. Yet there are problems with this method also.

Animals and plants contain abundant carbon. And since helium is a gas, it can leak through the rocks and will eventually escape into the atmosphere. Con cites Bowman, a scientist who vigorous supports the accuracy of carbon dating. Note, for instance, that light coming to Earth from distant stars which in some cases emanated billions of years ago reflects the same patterns of atomic spectra, based in the laws of quantum mechanics, that we see today. That allows carbon dating to be used to cross-check, say, tree riings and coral growth rings. This is based upon the spontaneous breakdown or decay of atomic nuclei.

Creation 101: Radiometric Dating and the Age of the Earth

So, if you happened to find a rock with 1 microgram of potassium-40 and a small amount of argon-40, would you conclude that the rock is 1. Lee in the Anthropological Journal of Canada, said that artifacts found in the area of a volcano can give erroneous ages of up to 4,000 years. As it turns out, there is compelling evidence that the half-lives of certain slow-decaying radioactive elements were much smaller in the past. Contrary to the impression that we are given, radiometric dating does not prove that the Earth is millions of years old. We have clearly set out the worldview within which we are working: we believe the Bible is the true revelation of the Creator God who made this world.

If the earth were young this is exactly what we would expect. A fossilized baby mammoth nicknamed Dima, was dated by Dr. If we neglect this then our age-estimates will be inflated by a factor of ten or so. This is used to date volcanic rock to the time the volcano erupted. Scientific justification for this assumption is found for example in.

When he writes for his religious audience he denies them. In counting tree rings, very rarely, two growth rings can occur in one season. Explanations like time speeding up or physical laws varying don't work because time and physical laws would have to be different for each isotope and each physical dating mechanism to get them to all to agree. A less than 10 year old sample should have no measurable Ar. To deny even the possibility that the supernatural may have had some hand in anything is to contaminate science in the same way that atheists accuse creationists. How do we know exactly how much potassium was originally in the volcanic rock? Response: This is not true at all.
