Imagine what the ocean floor would have looked like 150 million years ago, when all the rocks younger than that did not yet exist.

How would things have changed by 80 million years ago?

In general, in one half-life, half of the parent will have decayed.

In two half-lives, half of the remainder will decay, meaning 3/4 in all will have decayed.

Therefore, my main concern is with rocks of the Cambrian periods and later.

Back to top Radioactive elements decay gradually into other elements.

However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over 500 million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.

We are told that of all the radiometric dates that are measured, only a few percent are anomalous.Many dating methods seem to give about the same ages on meteorites.Thus radiometric dating methods appear to give evidence that the earth and meteorites are old, if one accepts the fact that decay rates have been constant.Potassium is present in most geological materials, making potassium-argon dating highly useful if it really works.Potassium is about 1/40 of the earth's crust, and about 1/10,000 of the potassium is potassium 40.
