Datare radiometrically dating, the Radiometric Dating Game

This is taken as proof that the continents began separating about million years ago. We now consider whether they can explain the observed dates. And faster cooling could increase the ages by further large factors.

But it's not evident how much support this gives to radiometric dating. So it is difficult to know what would be a reasonable test for whether radiometric dating is reliable or not. Since we do not know whether or how much human judgment is influencing radiometric dating, error validating server certificate fo a double blind study is most reasonable.

Thus these ages, though they generally have a considerable scatter, are not considered as anomalies. The same applies to all nucleii, implying that one could get the appearance of age quickly. It seems to me that a single lava flow might not mix well, and thus the age obtained would be that of the magma and not the time of the flow. Or it could be that such a distribution of argon pressures in the rocks occurred at some time in the past.

Let's apply all known dating methods to Gi that are thought to apply to this kind of rock, and obtain ages from each one. Igneous rocks are particularly suited to K-Ar dating. For a lava flow, this could be the time of the flow. But anyway, I think it is important really to know what patterns appear in the data to try to understand if there is a correlation and what could be causing it. This will retain the isochron property, but will make the isochron look too old.

Suppose X is a parent substance, Y is its daughter, and Z is a non-radiogenic isotope of the daughter. It could decrease them, if they were regarded as flukes.

At the temperature or pressure, collisions with stray cosmic rays or the emanations of other atoms may cause changes other than those of normal disintegration. It seems reasonable that gas would collect at the top of these chambers, causing artificially high K-Ar radiometric ages there.

The next time is starting stop. Gentry also finds a variation in the haloes leading him to conclude that the decay constants have not been constant in time. This also makes data about percentages of anomalies less meaningful. He cites another reference that most igneous bodies have wide biostrategraphic limits. And it should not be restricted to just one or two well-behaved places, but should be as comprehensive as possible.

The following quote is from the article by Robert H. Measurements were later made in an excellent collection of samples with haloes. Models yield isochron ages that are too high, too low, or in the future, sometimes by orders of magnitude.

It could determine whether a point can justifiably be tossed out and the remaining points used as an isochron. Coffin mentions that fission tracks can survive transport through lava, for example. It had been noted that some minerals which yield such dates as beryl, cordierite, etc.

In general, the dates that are obtained by radiometric methods are in the hundreds of millions of years range. At the moment of formation, as two nucleii collide, the uranium nucleus will be somewhat unstable, and thus very likely to decay into its daughter element.

Back to top One often hears about K-Ar dates of the Atlantic Ocean bottom which increase from zero at the mid-Atlantic ridge to about million years at the edges. Samples giving no evidence of being disturbed can give wrong dates.

This was a reference by Hurley and Rand, cited in Woodmorappe's paper. These anomalies are reported in the scientific literature. Imagine a uranium nucleus forming by the fusion of smaller nucleii. Whole rock isochrons may also tend to be wimpy, for the same reason.
