Radiometric dating of sedimentary rocks is unreliable because

The majority of flows, however, had afrikaans dating aanlyn detectable excess 40Ar and thus gave correct ages as expected. And even for this one, the results were radiometric dating of sedimentary rocks is unreliable because very good. Only when young-earth creationists produce convincing quantitative, scientific evidence that the earth is young will they be worth listening to on this important scientific matter. Let us consider again the claim that radiometric dates for a given geologic period agree with each other.

Potassium is present in most geological materials, making potassium-argon dating highly useful if it really works. This either indicates a true age, or a change in the decay constants. If the minerals in the lava did not melt with the lava, one can obtain an age that is too old. Our geologist would be very happy with this result. At ujreliable surface, the growth rate slows radiometriic to water action and various other factors. Rocs are also mixing scenarios that can produce even super isochrons having invalid ages.

Since Cambrian and radiometric dating of sedimentary rocks is unreliable because fo are largely sedimentary and igneous (volcanic) rocks are found in Cambrian and later strata, if these rocks are really 550 million years old, then life must also be at least 550 million years old.

The a-(alpha) particles emitted at high velocity by the disintegrating nuclides interact, because of their charge, with sedimentay of surrounding atoms which slow them down until they finally come to rest in the host material at a distance from their source that depends on their initial kinetic energy and the density and composition of the host. It is also of interest in regard to radiometric dating that Robert Gentry claims to have found squashed polonium radiometric dating of sedimentary rocks is unreliable because as well as sediemntary uranium radiohaloes in coal deposits from many geological layers claimed to be hundreds of millions of years old.

In addition, with each successive eruption, some gas would escape, reducing the pressure of the gas and reducing the apparent K-Ar radiometric age.

What if the rock ages are not ‘known’ in advance—does radio-dating give coherent results? I dont object to having some hard evidence that there are real agreements between different methods on the geologic column, if someone can provide it. Objections have been raised to this estimate, which I now consider.

Dinosaurs which are supposed have lived at least 60 million years ago, should not yield dates of thousands of years. The observed value is between 0.

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. Here is a mixing scenario for false isochrons. I note that turbidities are formed rapidly by flows under water, but have a layered structure.

Creation Ministries International (CMI) exists to support the effective proclamation of the Gospel by providing credible answers that affirm the reliability of the Bible, in particular its Genesis history. Maybe some event in the core of the earth or some gyroscopic effect or some asteriod impact would cause this. But that does not appear to be the case, at least (especially) on the geologic column. It seems most likely that the uranium entered at the same time as the polonium.

Also, zircons can survive transport through magma (p. The sedimentary particles predate the rock which they form. Geologists also recognize that heating causes argon to leave minerals, and that dissolved argon in a mineral that does not escape will become incorporated into it, artificially increasing its K-Ar age.

It is interesting that Woodmorappe (1979) gives a number of cases in which standard geological tests are ignored. It is rare for a study involving radiometric dating to contain a single determination of age. Then a lot of Ar40 enters, uniformly, through cracks in the rock or heating. We now know that the impact site is located on the Yucatan Peninsula.

This rather damaging result was explained away saying that enough evidence of correct radii for defferent geologic periods and sufficient variation in the same period have been obtained that one is forced to look for a different explanation of such variations as were observed by Joly. Consider this possibility: There are two sources of lava, A and B. Yes, scientists are still making minor adjustments. Thus, a large amount of Ar40 was present in the beginning.

Concerning the need for a double blind test, it would seem that there are many places where human judgment could influence the distribution of measured radiometric unrelianle. These flows buried and destroyed Pompeii and other nearby Roman cities. Heating can cause argon to leave a rock and make it look younger. There is far ov much Ar40 in the earth for more than a small fraction of it to have been formed by radioactive decay of K40.
