What type of rock is used for radiometric dating
He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.You can then infer that the dino must have lived some time between these two age dates. Wiens has a Ph D in Physics, with a minor in Geology.Radioactive elements decay at a certain constant rate and this is the basis of radiometric dating.
Sedimentary rocks may have radioactive elements in them, but they have been re-worked from other rocks, so essentially, there radiometric clock has not been re-set back to zero.Assuming a strictly literal interpretation of the week of creation, even if some of the generations were left out of the genealogies, the Earth would be less than ten thousand years old.Radiometric dating techniques indicate that the Earth is thousands of times older than that--approximately four and a half billion years old.Unfortunately, much of the literature available to Christians has been either inaccurate or difficult to understand, so that confusion over dating techniques continues.The next few pages cover a broad overview of radiometric dating techniques, show a few examples, and discuss the degree to which the various dating systems agree with each other.
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
