Talkorigins radiometric dating How Good Are Those Young-Earth Arguments?

Talkorigins radiometric dating, claim cd010:

Rates of radiometric decay the ones relevant to radiometric dating are thought to be based on rather fundamental properties of matter, such as the probability per unit time that a certain particle can "tunnel" out of the nucleus of the atom.

Claim CD011:

Various attempts were made as far back as the s to scientifically estimate the age of the Earth, and, later, to use this to calibrate the relative time scale to numeric values refer to "Changing views of the history of the Earth" by Richard Harter and Chris Stassen.

Converting the 4 billion atoms to grams a nickel weighs 5 gramswe get 0. Thus, we have a rough check between varves in glacial lakes and radiocarbon dating. Two extensive K-Ar studies on historical lava flows from around the world 3179 showed that excess argon is not a serious problem for dating lava flows.

The numbers above are just summary values.

Current estimates of the dating of the Earth indicate that the crust contains about 1. Thus, we can dismiss this young-earth argument. A careful choice of samples will often minimize contamination. Look again at the isochron for the meteorite Juvinas Figure 3.

If the rock is heated or melted at some later time, then some or all of the 40 Ar may be released and the clock partially or totally reset. The fact that the process is probabilistic, and the exponential dependence on time, are straightforward consequences of quantum mechanics. Dalrymple does not provide a reference for his free online dating hong kong section values.

The most common form of this young-Earth argument is based on a single measurement of the rate of meteoritic dust influx to the Earth gave a value in the millions of tons per year. Background Stratigraphic Principles and Relative Time Much of the Earth's dating consists of successional layers of different rock types, piled one on top of another.

A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims

The young-Earth argument goes something like this: This conclusion was clearly stated by both Wasserburg and others and by Faure and Powell Since the decay rate is also unsettled, values of these constants are chosen which bring potassium dates into as close correlation with uranium dates as possible. If the requirements of the method have been violated, the data clearly show it. The correct radiometric age is, of course, the scientific value of million years. There was also an attempt by Slusher and Rybka to invoke neutrinos. Alpha decay occurs when an alpha particle a helium nucleusconsisting of two protons and two neutrons, is ejected from the nucleus of the parent isotope.
