Uranium series dating

Attempts to date cave paintings illustrate the difficulties of radiometric dating, and also show evidence of a young earth. A recent article about U-series dating of Paleolithic art in 11 caves in Spain 1 contained some frank discussions about the wild assumptions that had to be made to date the paintings, and raised some interesting questions about the scientifically accepted age of the Earth. Although Paleolithic art has nothing to do with evolution, the article does give us an opportunity to talk about dating techniques in general, and U-series dating in particular. Furthermore, the measured levels of uranium isotopes are nowhere near what the Old Earth model predicts. All dating methods depend upon measurement of something that varies with time.

Radiometric dating or radioactive dating is any technique used to date organic and also inorganic materials from a process involving radioactive decay. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. The radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time.
Three of the most clever techniques utilize uranium, volcanoes, and trapped electrons. Did you know that scientists can tell how old a cave painting is by dating the rocks on top of or underneath it? Like radiocarbon dating , Uranium-series U-series methods rely on radioactive decay.
