Why methods in general are inaccurate Back to top I admit this is a very beautiful theory. We can assume that the Precambrian rocks already existed when life began, and so the ages of the Precambrian rocks are not necessarily related to the question of how long life has existed on earth. This was a reference by Hurley and Rand, cited in Woodmorappe's paper. In a few cases, beste norske dating argon ages older than that of the Earth which violate local relative age patterns have even been determined for the mineral biotite.
Yes, radiometric dating is a very accurate way to date the Earth. This list is not exhaustive. They also pointed out that for the anomalies to be accounted for by excess argon, unreasonably high partial pressures of Ar during crystallization would have to be required. Ground-water and erosional water movements could produce this effect naturally.
For each geologic period and each dating method, we will get a distribution of values. In uranium-lead U-Pb dating of zircon, the zircon is found to exclude initial lead almost completely. The precision of a dating method depends in part on the half-life of the radioactive isotope involved. Whatever is making some of these dates inaccurate could be making all of them inaccurate. The thrid is radiometric dating, but if radiometric dating is inaccurate so will the age of the ice core.
These were then eroded and Sedimentary Rocks B were deposited. In general, in one half-life, half of the parent will have decayed. Pro is correct when he asserts there are different methods of decay. So these small particles of lava cool very fast.
He assumes therefore that Sedimentary Rocks A are the same age as the other rocks in the region, which have already been dated by other geologists. It's not as easy as it might sound. This suggests that what is occuring is some kind of a mixing phenomenon, and not an isochron reflecting a true age. The following quote is from the article by Robert H. Furthermore, google it is theoretically possible for radioisotope decay rates to have been accelerated as a result of changes to the strong and weak nuclear forces within parent isotopes.
Models yield isochron ages that are too high, too low, or in the future, sometimes by orders of magnitude. Most Speleotherms in modern caves are not growing. This would be less than one part in a trillion entering the rock each day, on the average.
Assuming we start out with pure parent, as time passes, more and more daughter will be produced. Scientists are trained to discover such problems and to avoid them. This will cause them to retain argon and appear too old. This is when the dinosaurs are assumed to have become extinct.
- The same applies to all nucleii, implying that one could get the appearance of age quickly.

Some nuclides are inherently unstable. When lava is hot, argon escapes, so it is generally assumed that no argon is present when lava cools. There has been discussion on this issue in Journal of Creation. Don't attack individuals, denominations, or other organizations. If a rock dates too old, stillwater hook up one can say that the clock did not get reset.
And faster cooling could increase the ages by further large factors. Other methods do not require knowing the initial quantities. However, he fails to see that the evidence he has presented has been uniformitarian-inspired, which is just a naturalistic philosophical lens through which all his data has been interpreted. How can something be accurate and yet wrong?
Samples are exposed to neutrons in a nuclear reactor. The method critics employ is like searching for broken wrist watches, and upon finding a dozen, then claiming that wrist watches are utterly useless for telling time. Where they finally stop to produce lattice distortions and defects there generally occurs discoloring or darkening.
More recent studies have been made by Robert V. Aside from the theory having no scientific foundation, it is contradicted by all the dating methods that cross-reference carbon dating. For the purposes of assessing accuracy, each of the methods is assumed to be applied in accordance with the established methods and technology.
Radiometric Dating Is Not Inaccurate
So if a rock has tiny cracks permitting gas to enter or escape or permitting the flow of water, the radiometric ages could be changed substantially even without the rock ever melting or mixing. Not infrequently such resetting of the radiometric clocks is assumed in order to explain disagreements between different measurements of rock ages. One common radiometric dating method is the Uranium-Lead method.
So, then, careful scientists have measured variations in halo radii and their measurements indicate a variation in decay rates. Has someone really reviewed the thousands upon thousands of tests to derive that statistic? How do we know that maybe all the rocks have excess argon? If the radiometric dating problem has been solved in this manner, then why do we need isochrons, which are claimed to be more accurate?
It is claimed that the argon that enters from the atmosphere or other rocks, is less tightly bound to the crystal lattice, and will leave the rock at a lower temperature. Putting the starting strength where it wouldn't melt the earth it could only be decaying for years. In general, the dates that are obtained by radiometric methods are in the hundreds of millions of years range.
Fluorine absorption Nitrogen dating Obsidian hydration Seriation Stratigraphy. For example, a problem I have worked on involving the eruption of a volcano at what is now Naples, Italy, occurred years ago with a plus or minus of years. This would make them appear old.
This debate has been configured to only allow voters who meet the requirements set by the debaters. This paper also discusses Mount St. If the decay rate had accelerated in the past the a-decayers would have been accelerated more due to their mode of decay, atomic weights, and half-lives. The process of radiogenic dating is usually done using some sort of mass spectrometer. This temperature is what is known as closure temperature and represents the temperature below which the mineral is a closed system to isotopes.
Debate Radiometric Dating is Accurate
No physical mechanism for that has been suggested and none demonstrated. Especially the gaseous radioactive decay byproducts such as argon, radon, and helium are mobile in rock. Other flows with wide biostratigraphic limits have weak restrictions on allowable dates. My opponent, therefore, sex dating one night must explain the substantial amount of C found in coalfields that are millions of years old and diamonds that are billions of years old.
- We now consider whether they can explain the observed dates.
- This could happen because of properties of the magma chambers, or because of argon being given off by some rocks and absorbed by others.
- Also, as the rock deforms under pressure, more cracks are likely to form and old ones are likely to close up, providing more opportunity for argon and other gases to enter.
- They can then look at a single mineral, and using an instrument called a mass spectrometer, they can measure the amount of parent and the amount of daughter in that mineral.
