Radiometric dating of rock strata

If this rock is above a fossil, that fossil can be dated as “older” than the volcanic rock above it.

article on “Archaeology” explains: “Potassium-argon dating provides approximate dates for sites in early prehistory.

Yet when you look into the technical papers on these discoveries, you find that these dates are often questionable and are sometimes clearly in error.

Several types of radiometric dating methods are used today. When a plant or animal dies, the carbon in it has a small amount of radioactivity.

Geologists use this method to date volcanic rocks that may be as much as 4 billion to 5 billion years old.

Potassium is one of the most abundant elements in the earth’s crust.

Evolutionary theories cannot do what is claimed for them, even when given long ages in which to do it. As noted in the preceding major article in this Encyclopedia (), actual human records reveal that past time has been very short.—pp. Instead, only those dates are used which nicely support evolutionary theories. Evolutionists need long ages in order to pretend that their theories are true. There are three primary radioactive dating methods: (1) uranium-thorium-lead dating, (2) rubidium-strontium dating, and (3) potassium-argon dating. Each of these dating methods can only be accurate if each of the following assumptions always apply: 1: Nothing can contaminate the parent or daughter products during the process.

Yet, as we found in , non-radiogenic dating methods show the moon to be only a few thousand years old.—p. Tens of thousands of tests, costing millions of dollars in salaries and lab time, have been discarded because they have been found to be useless. Of the 1,400 radioisotopes known to exist, only 75 have half-lives longer than 700 years.

Carbon-14 has a half-life of 5,730 ± 40 years—, half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. “It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.” There are also other radiometric dating methods that are used to date strata and fossils.

Yet, as we shall learn in this article, evolution teaches that, if given enough time, a cow (or some other mammal) will eventually swim out into the ocean and become a whale.—pp. 5: If any change occurred earlier in certain atmospheric conditions, this could profoundly affect radioactivity. 6: Any change in the Van Allen radiation belt would greatly affect the rates, and that could also have occurred.—pp. Each of these five problems is very, very likely to have occurred over past time, thus devastating the value of the computed dates: (1) Lead could originally have been mixed in with the parent substance.

(2) Part of the uranium and its daughter products could previously have leaked out.
