He concluded that Earth was born 20 to 400 million years ago.Today’s scientists believe that answer is incorrect, but Kelvin’s calculations were in being based on logical thinking and mathematical calculation.These assumptions include: 1) the initial amount of the daughter isotope is known, 2) neither parent or daughter product has migrated into, or out of, the closed rock system, and 3) decay has occurred at a constant rate over time.But what if one or some combination of these assumptions is incorrect?

In order to use the valuable information provided by radiometric dating, a new method had to be created that would determine an accurate date and validate the assumptions of radiometric dating. Isotope dating satisfies this requirement, as daughter products do not decay back to the original parent element.In other words, the magnitude of the radius of a pleochroic halo in a particular crystal depends on the half-life of the decay responsible for the alpha particle emission. the radii of pleochroic haloes corresponding to a definite decay in a particular mineral are ...(the same) size, then it can be safely assumed that the half-life of that decay is a constant.In the early part of the 20th century, scientists still weren’t sure how old Earth is.Nowadays, scientists use radiometric dating of various sorts of rock – both earthly and extraterrestrial – to pinpoint Earth’s age.However, not as well known is the fact that such methods have serious flaws which are often glossed over, or ignored when writing on, or discussing this subject in public. that (the) half-lives (of uranium-thorium-lead) are not constant but vary with time. comes from the study of pleochroic haloes which form in a rock in the following way.
