However, it's obvious from Dr. If there is a leaking part in the batch as indicated by the response of the leakdetector , the batch is divided and each division is retested. Humphreys has no excuse for either ignoring or incompetently misinterpreting the equations and data in Magomedov 1970. These fluids need not be close to magmatic temperatures 650°C and higher. I noticed that you mentioned that this article was published in the Journal of Creation. According to the trend line, the predicted magnetic moment for Uranus is 5.

Helium Diffusion Age of 6,000 Years

The semiquantitative at best nature of the helium Q results for samples 5 and 6 must be remembered when evaluating Humphreys et al. Equation 17 is simply a rearrangement of equation 14c and states: Because , Figure 8, p. In response to the possibility of extraneous helium in their zircons or claims by their critics that high helium concentrations could exist in the biotites surrounding their zircons, , p. Using the same logic, I could just as easily turn around and say that any claims made by evolutionist sources are not reliable either, since they are just as biased as creationists are. Nevertheless, what kind of a person believes that he can know the motives of a stranger by reading a brief book review and using the Bible as a crystal ball? The argument, presented in a creationist journal goes like this: The rock formation is radiometrically dated at about 1.

Careful observations of the actual zircon data in Humphreys et al. Humphreys never carefully read Harrison et al. Humphreys has an English translation of Magomedov 1970 , it's obvious that he did not carefully study the article and its equations. Ken Farley was not allowed to have a more prominent role in the efforts of Humphreys et al. As discussed below, there are numerous incidences where Dr. The diffusivity for the green curve the creation model was computed by dividing the difference in helium concentration by 6,000 years. That suggests the zircon and biotite were near equilibrium in sample 6, thus supporting our hypothesis.

I ran more steps, with a drop in temperature after the 500ºC step, to see if the phenomenon is reversible. The whole right side of the author's Table 1 is in parentheses, except for the deepest sample. Gary Loechelt and me , he continues to ignore that fact that my essay at Talkorigins was peer-reviewed by a number of scientists see the discussions below and the Acknowledgements of this essay for the names of some of the peer-reviewers. Rather than accepting that the assumptions in Gentry et al. Henke acknowledges eight peer-reviewers, and several others who helped with the manuscript. The crystal would have a small but non-zero helium diffusivity and zero solubility.

But how else can we describe the actions of? Additionally, the Fenton Hill borehole site is located only about one kilometer from the western boundary of the volcanic and helium-bearing Valles Caldera , p. Chemical data in Gentry et al. Humphreys' documents are important, there is a danger that all of us including Dr. The x-axis represents the increasing amount of parent element; the y-axis represents the increasing amount of daughter product. As is typical, these data are taken at higher temperatures and extrapolated down to the regime close to the closure temperatures and ambient temperatures at which the samples were found. After that, in the summer and fall of 2002, we tried several times to get lower-temperature data.

Helium Diffusion Rates in Zircon Crystals Prove a Young Earth

However, it is doubtful that such studies would support their Genesis agenda. Thus, they could not have been exposed to elevated temperatures during the last 6000 years. In that work, zircon specimens were obtained from the Gold Butte formation in southeastern Nevada near Lake Mead. There would be no change over time in a steady state mode. Feldspar from hottest parts of borehole lost some argon In the laboratory, the first argon emerging from a sample comes from the outermost parts of the crystals.

Table 1: Information on the Fenton Hill, New Mexico, well core from , p. Humphreys probably hopes that all of these errors would somehow miraculously cancel out and preserve his bogus creation date of 6,000 years. This is a pitiful way for any individual to live — full of terror and desperately seeking any excuse to smear science and the actions of anyone that dares to see the world differently. They then spread their delusions and slanders into the general population. Boyd Hebrew , Eugene F.

RATE's Ratty Results: Helium Diffusion Doesn't Support Young

So a few frightened fundamentalists will stoop to any libel to discredit people who have honestly been devout Christians and found it wanting. Humphreys' figure is not the stunning result as proclaimed by Humphreys 2005a and Humphreys 2008b. As shown in the following quotation, , p. The only measured dates for the Humphreys et al. Humphreys, but also astrologers, water witches, advocates of petroleum conspiracies, and medical quacks. That is consistent with ordinary diffusion: a high concentration of helium in the zircons diffusing outward into a much lower concentration in the surrounding minerals, and diffusing faster in hotter rock. These issues must be kept in mind when evaluating Humphreys et al.
